general faq's
This section deals with general frequently asked questions about ErgVideo and its operation or features. If you are having a technical problem or seeing an error message, scroll down to the next sections called "Technical FAQ". You'll probably find your answer there.


You will need an internet connection on the computer on which you use the product. We are finally breaking from supporting unconnected computers from here on forward.

It's to deliver the services people are asking for, with the level of convenience everyone expects today. When we started, people were leary about applications that automatically queried the web for account info. Our old model was built to satisfy that. Those concerns seem completely gone now, and customers want one-click convenience, features that are all "in-app" that have no interactions needed outside of the app. Fully 100% of major customer-requested features assume that an internet connection is present and fundamental to that feature. From downloadable content, to uploadable performance data to various services, to convenient license management, to the raft of cool things WE'VE conceived to deliver in the future: they all need a connection. We're calling an end to developing, testing and supporting feature variants that permit "no connection" functionality. Doing so basically strains resources just to prop up a diminishing segment, and it's now clearly unprofitable to continue down that road.

Finally, the present competitive environment of our application-space is loaded with mobile-capable, fully-connected, always-on applications. Clearly the market of users can bear the requirement for a connection, and we can leverage some neat new features that will emphasize our still-unique value prop. So we're going for it.

If you have no wifi or your pc is located too far from your home wifi node

Always best is running an ethernet cable to your router/modem. Finding a way to do that is well worth the modest expense. It opens up the possibility to download new ErgVideos on a fast link. Now, if there is no way to reach your home modem from where you ride whether wired or Wifi, let's use your cell phone and its data plan. Now, before I suggest this, be warned I DO NOT RECOMMEND you use this connection to download ErgVideos(!!) because you will likely exceed your monthly data quota in about 1/2 a video. But this suggestion will get you connected for the purposes of authorization and account login etc. for ErgVideo 4.5 features, and the data exchanged each time is a few kilobytes, less than a typical email of text.

  • If your PC has Wifi already: pair your phone to the wifi to bridge to your phone's internet data connection. Every mobile OS now supports "tethering" as this is called. Now you are connected and you can authorize.
  • If your PC does not have Wifi built-in, sSearch your favorite source for gadgets on "USB to Wifi adapters" and pick the $18-$25 unit you like. Now your PC has a wifi link that your phone can discover and pair to. Again, now you are connected well enough to use the new easy authorization features.

We have so many choices in ErgVideo™ content, this sort of question is the result. Those who ask will often try to describe the type of riding they do, and whether they have a competitive focus on road, or tri.  There are a ton of common workouts from which both roadies and triathletes will benefit, so as a first time buyer, a distinction need not be made. We've packaged two "starter packs" to address this question. They are selected to show the full breadth of the product's features, quality, and usefulness in your training. 

The "Starter Pack 3" shows you a full mountain climbing experience (often the very first thing that attracts a new ErgVideo™ customer), and a hard tempo training session that shows the full-speed group riding experience that ErgVideo™ can provide.  The third video in the pack is the most popular intervals session in HD, suitable for all cyclists. This one will get you hooked because it really shows how effective and fun interval training can be in the ErgVideo™ system.

Some people want to take advantage of deeper discounts available at the 6-pack level, even on their first purchase. The "Starter 6-pack" includes the same ErgVideos™ as in the "Starter 3-pack", and adds the Threshold Test ErgVideo™ to help you regularly, consistently, and accurately determine your threshold power to be used in ErgVideo™ sessions.  We add the 4-man TTT, an extraordinarily dynamic and fast session where you will feel the drafting effects...except when it's your turn to pull. It's an over-under workout like no other, and it's a huge hit with roadies and triathletes alike. Finally the pack adds one of our hardest races, the Grand Prix de Blaineville, held on a criterium-sized (and shaped) course, but with a massive hill every lap.  It's aggressive, dynamic, and hard, just like a real bike race. It shows how ErgVideo™ uniquely re-creates the racing experience to help you train for the real physical demands of such an event.

No, you don't absolutely need a smart trainer, and indeed we market this product for use with manual trainers. But the experience with a smart trainer is vastly different and superior compared to using a manual trainer. The key is that the trainers will automatically control the load to precise power levels according to the workout. With a manual trainer you will be adjusting the resistance by hand, frequently, as you ride. Even if you have a power meter on your bike, you will be watching it constantly, trying to meet the target power levels that ErgVideo™ will display. While it works and many customers are satisfied with this, having a smart trainer means all of the power-tracking is done automatically, keeping you always at the set-point power despite your speed or gear. All you really need to do is watch the action and keep pedaling. The end result is a workout that's always exciting, you can watch the ACTION and not the numbers, and you are always on-target for your training. It also pushes you to succeed and complete each interval or effort. With a smart trainer, you will get to watch the video more closely, involve yourself emotionally with the action, and your experience will be 10 times better than with a manual trainer, with or without a power meter.

The main difference is that ErgVideo™ is power-profile based, and other simulations are elevation-profile based. ErgVideo™ operates in what is known as "Ergometer mode", and products like RacerMate™ RCV operates in elevation profile mode, what I'll call "3d" in this discussion, to indicate it is the same mode in which RacerMate's 3D operates. The Erg mode and 3d mode are vastly different, and I'll try to explain.

Let's first begin by recognizing that modern, successful cycling training is based on power measurement: workout sessions are often prescribed and always analysed based on the actual power output by the athlete during the session, not how far or how fast she rode. We know that many factors affect how far and how fast. For example, a rider can cover far more miles, faster, in a strong tailwind compared to a strong headwind, at the SAME physical power output. If the power output is the same, the physical development of the athlete in the session is the same, and the speed and distance covered are irrelevant to the athletic development. If you care to argue about cadence, well, make it equal too, and my point holds. Your CompuTrainer™ or VeloTron™ is a great tool with which to measure (and regulate) your sessions in terms of power.

In 3d mode, the resistance you feel is computed from the estimated real-life opposing forces you would feel when riding on a road with the currently displayed slope, or % grade. The 3d simulation computes this from your weight and the current slope (accounting for gravity and rolling resistance opposing forces), and your speed (your air resistance opposing force is computed based on estimated size and whether you have set a windspeed in your course file). The point is that on any given road or slope, you can choose to go hard, say at 300W, or easy at 100W. On the same slope, you will go faster in the first case, as in real life, but you can certainly choose to go slower at 100W. So when you ride outdoors with a power meter, ride a manual trainer with a power-meter, or when you ride in 3D mode and you want to "hold" a target power (per the goals or prescription of your training session), it is up to you to constantly watch the power level to keep on target. If you slow down, or gear down, your power goes down. If you speed up, it goes up. If you hit a hill, a higher contribution of your power must go into overcoming gravity, and if you don't slow down, your power will have to go up. Holding a "target" on the road or in 3d mode requires a great deal of concentration, gear and speed changes, and almost total focus on the power output number, rather than on the other excellent visuals presented. You will spend most of your concentration on these things, and your rides will become all about following the numbers....that alone becomes boring and more work than it should be. Any targeted ride you do in 3d mode will only be about watching the data, and regardless of the visuals, they will seem very much the same. You will be back to the boredom you had hoped to avoid by getting a CompuTrainer or power meter!

Erg mode completely turns this aspect of "needing to watch the target" on its head. The CompuTrainer actually takes-over the task of tracking power for you! If you set the CompuTrainer™ to 300W (say in stand-alone mode or Erg Mode in the Coaching Software), it will always FORCE you to do 300W, or stop! In Erg mode, the CompuTrainer is a feedback control system with power output as the set-point controlled parameter. Power is proportional to torque times speed. The torque is proportional to the magnetic force exerted against your riding by the load unit. The CompuTrainer computes your power output at every moment using the press-on force of the roller determined in the calibration phase (to compute rolling resistance contribution of your power), the current speed, and the current magnetic drag-force being exerted. It adjusts this force every 30ms. When it senses your speed go UP (seen as your attempt to increase power above set-point), the CompuTrainer will AUTOMATICALLY adjust the magnetic drag force DOWN in a manner that restores you to the target. The torque will go down so that the set-point target power (=torque x speed) is restored. Likewise when your speed goes DOWN, the load unit will INCREASE the braking force to make your power settle back to the target. You CAN pedal slower...but you have to push harder. If the power setting is above your ability to provide it, it will feel progressively harder until the CompuTrainer just stops you. The CompuTrainer is very good at making you hit the target. It only fails at very low power settings, where the rolling resistance power dissipation exceeds the setpoint power. For example, if you are going at a speed where the (calibrated) rolling resistance against the roller contributes say, 120W, and you have set the CompuTrainer to 80W, then it just turns off the magnets. It could only bring your power lower if it could relieve the press-on force or drive the wheel as with a motor. None of this is really an issue, since it's at piddly-low power levels anyway. It becomes an issue if you have applied very high press-on force, and that will affect the power level at which the CompuTrainer turns off and lets you just roll against the tight roller, uncontrolled. The Erg mode is the best way to be sure you execute your workout prescribed. You can't get lazy.

ErgVideo uses the erg mode so that you are FORCED to follow the racing and training action on the screen, and to feel the large power transitions required in a bike race, just as in a prescribed training session. Most people are initially surprised at being forced to perform. They expect the ErgVideo ride to feel like any other trainer ride where they have the ability to ignore the instructor, or take it easy whenever they feel like it. ErgVideo™ simply won't let you, unless you stop. You CAN make threshold adjustments on the fly if the workout really is over your head, so you can always finish your sessions at a lower than expected level, if you find your initial settings were overly ambitious. ErgVideo is pretty good at uncovering those who boast and exaggerate their fitness; there is no hiding.

Finally, now that you sort of get it, let's consider a flat 4-corner criterium course in 3d, vs an ErgVideo of a 4-corner crit. Now you can see in 3d there is no incentive at all to ride as if you are really in a crit, with large surges out of each corner, chasing down attacks. You will eventually just ride steadily as if riding on a flat ribbon of endless road, and you won't feel the corners and their need for deceleration or acceleration, either. In a criterium ErgVideo, the power you ride is a scaled version of the actual power output of the rider in the race. You will have to jump out of corners, and chase down the attacks, just as the cameraman had to. As well, in a crit, if you want to stay in the race, you can't so easily pick and choose when to go hard or easy, you have to follow what the race does. So here is where the "power profile-based" simulation results in a far superior simulation and event-specific workout for you.

We published a great newsletter in 2014 where we covered all of these aspects in great detail. It's here and it's worth a read.

First, maybe read the answer to question 3 above, and come back here if you still have the question unanswered.

You have to output the watts, but you are wasting your focus "trying" to match your watts to the display at every second. The reality is, YOU HAVE NO OTHER CHOICE but to output the power, since Erg mode implicitly forces you to match the prescribed need not "try" with your mind, anyway...just the legs. Consider that watts is Force x speed. If you go "over" the setpoint, say by speeding up, the CT adjusts load force down until, at the new speed, you are doing the target watts again, and if you go under target by slowing down, it increases force to bring you back up to target. There is a short transient and a little bit of fluctuation around the setpoint. You will see it if you examine your data after an intervals ride. Now, you do have to watch the ErgVideo power-profile display to see the large, fast power transitions, since if you do not output the target power in time, you will feel a HUGE increase in force you may never overcome or "catch-up to". So you have to be ready to push when the surges come. I just spin-up real fast..and hold it through the surge. The only time the set point-power tracking fails is when the power due to rolling resistance already exceeds the target set-point. Then the CT can only turn off the force of the magnets. It shows you riding at say 120W when the set point is say 50W. This is because your rolling resistance is causing the whole load, and the CT can't automatically reduce that to get you down to 50W. The only thing you can do then is slow down to bring down your power "manually" . You may also experience a case where your own power CAN be maintained below the setpoint power, and it doesn't appear to track as expected. In all such cases, it is because you are below the minimimum wheel speed where Erg mode actually works, and that's about 12mph. Select a gear and cadence that ensures you pedal above 12mph, and you'll find the power will track. Below 12, the CT is actually turning on and off as you cross the 12mph speed. It's a burn-out safety feature built into your trainer. If you are pedalling and grinding under 12mph anyway, your setpoint is far beyond your ability, adjust it.

If you are having a hard time being convinced, let me suppose that your threshold power is 250W. So it should be quite easy for you to hold, say 225W steadily. Change these numbers proportionally for your particular case. Set your rolling force so that after calibration spindown, you are about 2.0 to 2.2. When the roller is too tight, the rolling resistance contribution to power is higher. Put the RacerMate Coaching Software in "Manual ergomode" mode, and adjust the step for 5W increments. (options...manual ergo options). Start a ride with Start..manual ergo mode. Set the load to read 225W, or proportionally about 90% of your threshold power. You will see your power out will fluctuate around the load point of 225. Now, go ahead and accelerate up to about 300W on the power display. Try to hold it. You will see your power indeed go up, but curiously, it will start to fall toward 225 again, and you will need to accelerate again to go up to will come down....and so on until the only thing you can do is go REALLY fast, and at 2.0-2.2 rr, the speed you would have to go to keep the CT reading probably can't do it.

Now, try the opposite. Set the erg for 275W. Now, CONSCIOUSLY TRY to ride at only 170W on the power display. You will feel the CT force get heavier, and you will work up toward 275 you slow to try to hit 170....the CT gets heavier, and heavier.... this is erg mode. It is adjusting so that if you just keep pedaling, you will be forced up to the target power. The CT sees too little speed, so it increases force. Eventually you will not be able to continue pedaling. Try this at 400W...for fun. Like I said, you don't have to try, except to stay pedaling and just ahead of the big spikes in power. The only exception is when the power is set well below the level dissipated in RR. Examine this by setting the erg to 50W. Then you will easily be able to ride at 120W on the power readout. The CT is actually "off" and is computing your watts strictly from speed and the calibrated press-on force. Now when you put the CT to, say 140W, and stay at same speed, the CT computes 120W is still going to rr, and it ADDS enough mag force so that, at that speed, you will be doing 140W.

So really, you don't have to "try" to match watts with your head. You just will, except at the low end, where all you have to really do is pedal as easily as it will allow. This allows you to enjoy the ErgVideo action itself, and not have to watch a bunch of numbers. You can just turn off your mind, and just don't get caught behind the big spikes!

We published a great newsletter in 2014 where we covered all of these aspects in great detail. It's here and it's worth a read.

Yes, it is right. Please read the answer to question 3 above, and come back here.

Two riders can have the same power output, but can have different wheel speeds. Your wheel speed is simply a function of your gear and cadence. Recalling that the load unit keeps torque x speed at the target power, then the slower rider will simply have a higher torque applied at his load unit, compared to the faster rider. They will both be working exactly as hard as one another when the power is the same. So you can see now why trying to cover more distance than your partner, is rather irrelevant.

ErgVideo is designed to allow you to enjoy your workouts with partners by ensuring you each get the same workout relative to your own threshold power level, while sharing a common display of the action, and a common workout duration. You always start and end together no matter how fast you ride or how high your threshold is set. There is no way to finish before your partner, as in a race over a common distance. You are doing a workout over a common time. If you combine the answers above for question 3,4, and this one, you can understand that racing with ErgVideo is not really possible. If you try to race by trying to covering more distance, recall that the distance you cover is actually irrelevant, since you can cover different distances at the same power level simply by changing gear or cadence. The CompuTrainer adjusts the torque so you adopt the correct power regardless of speed. In the extreme example, suppose you were trying to cover more distance or the same distance faster than your partner. The best way to win is to REDUCE your threshold power to say, 0w or something terribly low. This means the CT will not be providing any load, and you can ride very fast and very easily against the roller resistance, in a huge gear. It's unlikely you will hit the target watts. You may cover many miles faster than your partner, but the end result is that your workout in terms of power and energy is useless, being executed actually at very low power. Its like "racing" someone who is confined to an uphill while you have a downhill all the way. Of course you will win, but it doesn't provide you with a proper physical workout at all.

We published a great newsletter in 2014 where we covered all of these aspects in great detail. It's here and it's worth a read.

No and...probably if it will be standards compliant only. Please don't call for a schedule. Per item 9, I can't and won't say until it's available at least for trial. We promise small, deliver big, rather than the other way around. We aren't looking at supporting proprietary protocols anymore, now that there is a FE-C standard for trainers. Buy an FE-C compatible trainer.See this article at Pez

As a corporate rule, we never pre-announce ANYTHING. We never speak about what we are doing and don't make estimates on their availability. This helps make our message absolutely clear: whatever we ever talk about or expose on the website, is available NOW. This helps kill rumour mills and makes sure you aren't waiting for something we never actually promised. The brutal truth is, while we have a schedule and plan for everything, it gets swapped around when high-priority opportunities arise. We need this flexibility to make the opportunities happen and can't be held back because we publicly stated that some minor feature like "the changing of the background colors to the whole rainbow" would be delivered in June 2.

As another example, you might be waiting for a video from XYZ location. Reality is I can go there with a full crew of riders and it can rain all week. Or I can drop the drives on the pavement as I get out of my car. When any of that happens, your videos from XYZ won't be happening. If I made the public promise that videos from XYZ are coming, it doesn't really help any aspect of my business when things get delayed.

So, once again, don't ask what's coming, go see what's here, now, and I promise, you can always buy it today.

That's correct. Our discounts are limited to the single customer buying a number of distinct videos for themselves. We've been approached by coaches, for example, who want to buy 9 licenses to the same single video at the 9-pack discount rate, to resell them to their athletes at a different (or the same discounted) price. We don't support this "distributor" model. It leads to us footing the expense to support many people who haven't paid full fair price to us for the product or service. Multi-pack discounts apply to single purchases by a single customer of a set of distinct ErgVideo titles.
No. Discounts apply only for the quantity of your individual purchase at a single time of purchase.
No. Some people feel it is necessary for ask for deeper discounts, saying "Well I just had to ask". Sure I get it. Cool, so I just have to answer.

Dual layer DVD's are required for some titles, due to the file sizes of HD videos. If your DVD reader is not DL compatible, the DVD will appear to have no files on it and will not launch the installer. Insert the DVD into a very modern PC, looking for a small "DL" on the drive door. If you see the files in Windows Explorer, you know the DVD is not blank. you can get a compatible reader for less than $30 as an internal, and almost that same price for an external USB DVD reader/writer.

We don't ship on DVD anymore.

You can run your ErgVideos from any hard drive on the registered system. The trick is to leave the right files in the c:\users\public\videos\ErgVideo folder (I am going to use windows 7 speak on directory names). You MUST leave ErgVideolibrary.xml and ErgVideolibraryRM1.xml in that folder. If you have training plans in that folder, you need to have the ErgVideoplanTemplate.xslt in the same folder too. These are all small text files and take up negligible space.

You can move the ErgVideo to any place on any hard drive (including externals, but if you try to run the ErgVideos on an external drive on a different computer, they will lock down and no longer be useful), but you must have the .evr file and the matching .wmv or .avi video file in the same folder.

When ErgVideo installs it creates a folder with the same name as the .wmv and .evr files. So for example, if you have Threshold Intervals HD, then you will have a folder called ThresholdIntervalsHD and inside is a file ThresholdIntervalsHD.wmv and ThresholdIntervalsHD.evr. There may be other small ones left-over from ErgVideo 2 if you ever had that. You can delete them. I recommend you keep the wmv and evr files together in distinct folders for each video, for convenience and any future proofing against updates in the software.

So, on the drive that you want to move to, make a folder "ErgVideo" and copy the folders for each ErgVideo into it, from your old place c:\users\public\videos\ErgVideo. Be sure the folders have attributes 'Readonly' as unchecked.

You will not have to re-register the videos, as long as this new hard disk is secondary on the same system that you originally registered.

Here is the trick though: Your library file is now out of date and it is pointing to the videos in the old locations. No problem. Open ErgVideo 3. Options...library and training plans tab...and select one of the videos you moved. Keeping with our example Threshold Intervals HD, select it and click 'Remove'. THIS OPERATION DOES REMOVE ANY CUSTOM RIDES YOU CREATED for that ErgVideo. Making the move while preserving custom rides requires text editing n xml and we don't recommend it. Now hit 'Add' and navigate to the NEW PLACE on the NEW DRIVE where you put Threshold Intervals HD and select the .evr file.

That updates the pointers in your library file and ErgVideo will always find your Videos. Repeat this process for all of the ErgVideos that you relocate from their default place. Don't be fooled with the pointer, it will point at first to the OLD locations and some people think they are doing it right, not realizing they are not pointing at the new location.

You can delete the video folders in the c:\users\public\videos\ErgVideo when you are sure you have copied them to the new drive, to achieve the space saving you were after.

The license agreement is the legal document outlining the terms to which you agree in order to receive a license to use ErgVideo on a single computer. It is strictly worded and does not at all have an interpretation that says "a single computer at a time". You unlock once. We won't write or state anything that would or could be understood as extending to you different license terms than the ones outlined in the agreement. With copyrighted material such as ErgVideo, you get a limited license to use the material, not full copyrights to the intellectual property contained. Requests for any exceptions are dealt with on a case by case basis, and will always involve an audit of your account and usage history, including whether ANY unauthorized use or additional licensing attempts have been made. Exceptions, if they are ever granted, do not extend revised license terms to you. We reserve the right to refuse granting exceptions, since upon installation and unlock on a single computer, the license purchased has been completely delivered and accepted by you.

We do not grant free serial numbers or licenses to enable a second pc, and we don't grant exceptions to commercial users (multirider centers) under any circumstances.

Without going into detail, a few things currently stand in the way, and let's face it, ErgVideo is a two‑man company, and one doesn't code. Currently a second stream of development, or even to restart development on a platform-independent framework, for a platform still only winning a small share of the desktop/laptop space (don't confuse iMac desktop with iPad/iPhone) is presently a tall order, and we're more focused on delivering as much content as quickly as possible. Such development will distract, resource...from that progress. Instead, it's more expedient for you to run iMac with Bootcamp to run Windows. It seems to be the best Mac solution overall, compared to VMWare or Parallels, judging from discussions with customers. We've seen one customer stuck with a brand new video card configuration in his Mac, but a bug-ridden Mac driver (or firmware) for it, that definitely delayed his enjoyment until drivers were fixed by Apple/Nvidia. Most problems we've heard about revolve around aspects of the graphical technology not correctly implemented in VMware or Parallels. Most are just little things easily overlooked, but they may annoy you. We think you are best-off using the product Apple builds and supports, Bootcamp. We can provide authoritative support for ErgVideo only inside the Windows boundary. If you have trouble running Windows on your Mac, that's an issue for Apple to help you resolve as it is a value-prop well-promoted upon introduction of the iMac itself. We won't help you experiment with the multitudes of solutions for running Windows on your Mac, that's your thing solve with Apple. ErgVideo works best in Windows 7 or 8, it is an extraordinarily stable and secure OS, and we're told by every Mac fan that Windows works great on an iMac, too.
The output file format for the standard RacerMate txt file has this info included. These fields must be present with some numbers for compatibility. However, parameters such as age, HR bounds, sex etc. have no bearing or influence whatsoever in the ErgVideo experience. We believe making the user set this information is unnecessary hassle and seriously, it's for nothing. So we see that as adding to the user-interface just too much garbage and clutter that serves no real purpose. It makes it look more complicated than it needs to be. When you use the file in a data analysis tool, you have to input that info AGAIN into the analysis tool anyway (for whatever purposes they deem is useful), they never take the info from the RacerMate file itself...or they shouldn't. So it bothers us to make you enter it in ErgVideo (for no purpose) knowing you are entering it AGAIN and AGAIN and AGAIN elsewhere. Life is too short.

Please review, for example: Wiki on Calories and Wiki on Food Energy.

Read those and you will understand why I'll never put calories/Calories/kCalories into ErgVideo. With Calories/calories/kCalories, it is never clear what is real work and what is understood as food energy 'burned', while kjoules is a proper engineering unit for real work (energy) done, and nothing else. The argument hinges on the presumed 'efficiency' of burning food energy, and what is spent on sustaining body temp and functions. A quick example is that some will say if a person uses 100kJ of energy to do a task (as moving a mass using 100N through 1000m), convert that to calories, and THEN multiply by 4 or 5 claiming those extra were burned just to stay warm and alive. Now the argument about 4, 4.5, 4.987 or pi.

Next argument is the claim that a person with more lean muscle mass will burn more calories at rest than a person with less, but same weight. And thus efficiency must take account of this, and thus the calories computation must, and then the question is : how?

I won't engage in this kind of ambiguity and will present only Kj as work 'done' not calories = Work + a feel-good bonus for staying at body temperature. If I did, my next raft of emails would be arguments about whether I should use 25% efficiency or 30%, or pi/8 and on what authority I chose which number.

My very best answer is 'I didn't'.

Work(kj) = Power(W) x time(seconds) plain and simple. Well, indeed it is more complex, it is the time Integral of power from time0 to time1, but it is still precise and has no assumption on body fuel burning efficiency or what percentage is needed to sustain body temperature and life functions.

At the end of each ride, as long as you end the ride or hit the stop button, you performance data is ALWAYS saved. Of course, if you hit the red x at the top of the window, the traditional Windows cancel/close app button, your data will not be saved.

Upon correct end/stop, a browser opens to show you summary data. There is ALWAYS a link that says "Click here to open data folder" which will do just that. Your performance is in that folder (Documents\ErgVideo Data\Performances) and is given an informative name.

ErgVideo 3 stores only in the RacerMate legacy txt format. ErgVideo 4 saves in the Garmin FIT activity file format and has been tested against TrainingPeaks, WKO4, Strava, and Garmin Connect. If you have difficulties with any other analyzer, please take up the issue with that particular company. We won't modify the format to accommodate bugs or limitations particular to one analyzer or another.

Please go back and read items 3,4,5 and 6. It is there where you will discover that speed and distance covered is irrelevant in ErgVideo. Of course, that ISN'T TSS, so how is this related?

We observe people riding ErgVideo with "racing the other guy" in mind, and often they will run-up the distance covered during periods of 0W load. Their goal is to make the distance reading increase, and maybe exceed their partner's. It's irrelevant since it's no-load pedaling, and in fact there is SOME load due to the rolling resistance of the CompuTrainer roller. But more importantly, the rider is NOT resting while the session is SPECIFICALLY meaning to let the rider rest (such as between intervals). The act of runnin-up the distance is actually COUNTERPRODUCTIVE to your training session.

Showing TSS as well will CLEARLY exacerbate this problem, since people will fixate on running up that number, and similarly NOT resting when rest is prescribed.

The net result of both these "racing" behaviors is that a rider becomes too fatigued to finish a session, they can't "complete on-target" and they will surely have to reduce their threshold setting as time progresses in the session. They will be frustrated with the training outcome. So, we see showing TSS in this application to be a counter-productive feature. Maybe we'll make it optional, but MANY coaches at centers tell us they turn off the distance and speed displays, so I expect coaches will also, rightly, disable a TSS display.

There is much more to the problem than simply the resolution of 1920x1080 pixels to show. It's also about the frame rate and the bit-rate, and these parameters also set the quality of the final image. Youtube will stream frame, bit rates and resolution based on your connection speed, and they aren't of the same quality you are getting with ErgVideo 1080HD. We've chosen a bit and frame rate that is a good compromise that provides a high quality image and compatibility with even what are consider to be low end machines by todays standards. We always encode using Microsoft standard VC-advanced encoders so that you never have to load 3rd party codecs. The quality is superb, and these will work on Windows system that meet the performance specification, with nothing new to load.
It's in Documents\ErgVideo Data\Performances. After every ride a summary shows and there is evena link to click that will open this folder for you. ErgVideo 4 saves by default to the .FIT file format, which is suitable for uploading to online services of your choice. All services worth a look have a way to select and upload the file. We haven't made it automatic because frankly writing API-accessing code bits for every one of the buh-zillion or so services people will request just isn't presently a priority given that people are clamoring for more videos. And since there is a simple way to upload your file to all of them anyway, well, you currently have a solution. Also, this way ErgVideo doesn't need to collect/store/protect your credentials for your online services, further complicating your setup.
technical faq's

This section deals with general frequently asked questions about ErgVideo's behavior and issues that may look technical to you. If you are having a technical problem or seeing an error message, you might find your answer here.

If you have a problem, the very first thing you should do is install the latest ErgVideo software, and perform a Windows-update on your system, installing all offered updates short of a full upgrade (if you don't care much for that...but windows 10 is great, and ErgVideo works fine with it!).


This is seems largely handled by an update to your video drivers directly from the manufacturer of the video card. Driver support was an early issue with Windows 10 and various video card drivers including Intel HD integrated, Nvidia, and AMD.

older news: this is (was) an IntelHD driver issue. Many people have PC's on Gen3 and 4 CPU's for which intel was very slow to supply working drivers on Win 10. It seems fixed now.

NEVER EVER EVER EVER go surfing and be enticed by a web page that asks you to install some piece of "easy driver fixes" package of any sort from a place that is not MS or your card manufacturer. They are most frequently malware and will totally make a mess of your machine. They live to prey on users for this stuff. Don't do it.

Update to the latest version. The version is in the upper left corner of the main ErgVideo Application window. Not there? Then you don't have the latest version! Get the latest version at the downloads and updates page. We improved the diagnostic reporting and you will get a more specific error message telling what the problem is, as well as an error log. If you contact customer support about this issue, please provide the diagnostic log.

Next, or equally: Windows update! Accept all updates offered for your OS version, especially for .net framework 4.0, and the USB ANT+ drivers. Some people have driver updates disabled. Enable them and look for the Dynastream ANT+ updates offered. There is a known fix to the framework 4.0, applied a long long time ago, but people who don't update their computers regularly will have this left un-patched. Speaking as a developer, the days of forced updates can't come fast enough. Please do that and try again.

Still not working...then the issue relates to some of your system security and UAC settings and what options you chose when downloading and installing. Please right-click the ErgVideo icon and select "Run as Administrator". Some users have found after running once this way, it will always run fine without requesting Admin. Others just look at the properties and configure the program to always run as admin. This should actually not be necessary, but if you find it is necessary to run ErgVideo on your machine, please let us know, and show us an error log generated when you do not run as admin. Remember, cranky Steve in customer service will berate you if the log indicates you are not using the latest version!

Finally, your Ant+ stick may be too old and we're not supporting the units without 8 channels and controllable power levels. See our ANT+ page. So remove the stick, launch the program. If it gets past that point where it would shut down before, you found the problem. You need a more modern stick. Most systems with an old stick throw an exception and a clear diagnostic record in Documents\ErgVideo Data\ErgVideoErrors. If you are using the latest software, a diagnostic log will be generated. Provide it when you contact support.

Upgrade to the latest version.

See item #1 above regarding older unsupported sticks.

Also, if other processes have started and take ownership of the stick first, ErgVideo can't see the sticks. Garmin Express does this, and because it's so common, ErgVideo attempts to terminate Garmin Express. Now, it should work fine whether you are an administrator or not, but we have seen 1 case where a customer claimed Garmin Express did not shut down unless he launched as admin. Okay, I can't recreate that on any system, but perhaps your system settings are different enough to thwart all of this. Please close ErgVideo, and right click on the ErgVideo 4 icon, select "run as administrator". You can configure it to ALWAYS "run as administrator" by checking the option under the compatibility settings tab. This way double-clicking the icon will be all you need in future. We are interested in hearing from you if you do require Admin privileges to run ErgVideo. It shouldn't be necessary, but send us the log generated when you don't. THERE IS NO NEED TO RUN ERGVIDEO IN ANY OF THE OS COMPATIBILITY MODES. It works fine on Win7, 8, 8.1 and 10, and setting a compatibility mode for win 7 when you are running win 10 may introduce more unknown issues.

If you are running other programs that have "owned" the stick first,(such as other applications that talk to your devices or Kickr), ErgVideo makes no attempt to terminate them, you will have to do that yourself.

Update to the latest version. It has a diagnostic for the case where you do not configure any trainers to stations. Please review the instructional videos. At the bottom of the page are specific use cases simplified, pick the one that matches your situation. You have not dragged and dropped the trainer icon (in rightmost table labeled "Trainers") to the STATION where the actual trainer is in your studio/home. They default to a manual trainer. Drag and drop the icon to assign the trainer to a station, and its data, along with the data from all devices assigned to the user at that station will show in the riding screen. You have to also drag and drop the rider, as well as any new ANT+ devices you want to show for that rider.

Please review the instructional videos. The error message is telling you about a configuration requirement needed to proceed. For example, in the case of "rider has not been assigned", it means you have not dragged the name of any rider to an active station, so basically...nobody is riding, and ErgVideo doesn't see much point in going forward. It's about riding, you see! Drag and drop a rider's name onto a station in the configuration screen. Similarly, the pop-up will point out other drop-dead configuration errors and try to steer toward fixing it.

Update your ErgVideo version.

This error is due to a problem in an early release of .net framework 4 and has long been fixed by Microsoft. Please do a windows update and apply all recommended updates, especially to .Net 4.0. You haven't been doing updates regularly enough. We guarantee that this is the fix. All case of this problem arising have been proven caused by the lack of update that MS issued years ago. By not updating your system, you leave your machine and data more vulnerable to nasties like viruses and malware.

Update to the latest version. It should throw a specific error that you do not have the right version of Windows Media player, and that can only happen on non-updated versiosn of Win XP and Vista. This error comes from your system's inability to read the media files with the correct codec, or you are using Windows XP and have not installed the current Windows Media player. For XP, the highest version available is 11 and you get it by opening WMP and click Help...Check for updates. After installing, restart ErgVideo. Please install the latest ErgVideo version available on the downloads page. Note that Windows XP is no longer supported by MS and you should be upgrading to 7 or 8. Future versions of ErgVideo will not even be tested on XP.

If indeed you find you are out of date on WMP, it's likely you haven't been applying windows updates either. You should do a full update of your Windows installation.

This error should never show on Windows 7 or 8, unless you have added some components that have displaced and harmed the standard video playback codecs or drivers.

If you have loaded 3rd party Codecs such as VLCplayer, DivX, or a codec pack such as "K-Lite codec pack" or "Media player codec pack", you have a new set of problems. The codec packs are REAL problems and often carry broken open-source components that may require you to re-install windows completely if you don't take special care in uninstalling them.

We built ErgVideo specifically to avoid the need for ANY 3rd party codecs. We encode the videos using MS-standard encoders that have guaranteed compatible decoders installed with Windows and Windows media player. We did this specifically to avoid "codec hell" that has evolved from 3rd party and open-source codec proliferation. Often the codec packs you install come with malware to the extent they can't be uninstalled without ruining your normal Windows OS video playback functions.

If you installed VLCplayer: This is probably the best media player of all short of WMP, and you can configure it to not playback .wmv files in VLCplayer's settings. Do that. Windows should use it's own codecs to play wmv and ErgVideos, if you haven't installed other garbage.

Divx: uninstall with it's supplied uninstaller. It's always broken for .wmv files >4Gb.

K-lite and Media player codec packs, or ANYTHING that installs "Media player Classic" as a feature: Uninstall using the provided uninstallers. Do not use the "control panel...remove programs". You will hose your system, and only recovery is full re-install of Windows from scratch. Back up your data files and programs, you will lose them all when you have to re-install windows from scratch. You gave these open-source programs permission to do whatever they did when you installed them. Beware. Please see the topic below on codecs before taking this drastic action.

If the problem continues, you have a video card driver that is not compatible with the newer technology ErgVideo uses. Go to the website of the video card manufacturer and get the latest driver and control software package. Install it, reboot and try ErgVideo again. After all of these steps are executed, if further issues persist it may indicate your system is below spec for ErgVideo. Please review the system requirements page.

We use .wmv files that do not require 3rd party codecs. If you have installed VLCplayer, Divx, K-lite codec pack, Media player codec pack or any other codec pack, please see the special topic on codec packs.

We have also seen that MANY video editors will corrupt a wmv file especially if they are >4GB. Typically the symptom you will see is a full freeze of video playback at some random point in your ride. If you ever opened the wmv file in an such editor, it probably re-saved the file with an error. We've even seen this with video cards from AMD with the option to "re-encode video for devices" enabled. We recommend turning that option off. You best bet is to get your original ErgVideo DVD or the backup you made upon downloading (as you were encouraged to do) and drag-drop the video file found in the folder that carries the video title. Drop it in the same folder where you installed the video (default is c:\users\public\Videos\ErgVideo\(insert videoname here)\(insert video filename here).wmv) Make sure you tell the OS to replace the file.

We use .wmv files that do not require 3rd party codecs. If you have installed VLCplayer, Divx, K-lite codec pack, Media player codec pack or any other codec pack, you need to uninstall or reconfigure them very carefully.

For more information have a look at the following Microsoft Windows article link:

If you installed VLCplayer: This is probably the best of all, and you can configure it to not playback .wmv files in VLCplayer's settings. Do that. Windows should use it's own codecs, if you haven't installed other garbage.

Divx: uninstall with it's supplied uninstaller. It's always broken for .wmv files >4Gb.

K-lite and Media player codec packs, or ANYTHING that installs "Media player Classic" as a feature: Uninstall using the provided uninstallers. Do not use the "control panel...remove programs". You will hose your system, and only recovery is full re-install of Windows from scratch. Back up your data files and programs, you will lose them all when you have to re-install windows from scratch. You gave these open-source programs permission to do whatever they did when you installed them. Beware.

Now scan your system with MS security essentials, or malware bytes if you like that. Then clean your registry clean with ccleaner by piriform software (download directly from their servers only).

Also be sure your system is set for full hardware acceleration in windows media player options, and in the display control panel.

Reboot and try again.

Before giving up, try the Sfc /scannow tool to try to recover the default codecs. I must say that a truly damaged system just needs a new image of Windows installed. That's why I call Codec packs "malware". They get permission from you to replace system files they should never touch.

This is about the ONLY problem class where I have had to recommend full re-install of windows. So please, avoid the codec packs. Oh, yeah, and a Windows install with no codec packs ALWAYS works, too.

You have managed to have the library 'point' to the dvd or some non-writable area of your hard drive.

DO THIS. If you did a default install, your ErgVideos should be in (Vista, Win 7, 8, 10) c:\users\public\videos\ErgVideo\your_video_title_here (they can be in a different spot, as long as it is a spot where you have read and write access, and not back on the dvd. I can't guess where you put it so I assume the default was used). Please check there is a wmv and .evr file in that folder with same name. If not, you did a non-standard install, and some people try to point the installer BACK to the DVD. You cannot run ErgVideo from the dvd, we do this specifically because you will wear it out, and dvd drives are notorious for random read errors in the presence of wear or dust.

So, now assuming you installed to some area of your HDD/SSD, go and make sure that folder and files are not checked as 'read only' in their properties (right click the folder and files to get the properties). The install procedure specifically sets these options, and the only way to avoid that is to not let the install complete or if you tried to install without using the installer.

Now, open ErgVideo...options...library and trainingplans...and select the entry (your_video_title_here). A correct install will have this showing. Click 'remove'. Now click 'Add'. Now navigate the dialogue to c:\users\public\videos\ErgVideo\your_video_title_here or {wherever_you_installed}\your_video_title_here and click 'open'. You will be asked to unlock, and as long as those files are not checked as read only, the unlock process will work fine. Guaranteed. You can update the library manually in "Options...Library and Training Plans...Add", and the common mistake people make is to point the file-open dialog to the DVD drive and not the image installed on your hard disk. Point to the latter.

We suspect what you will see upon the click of 'Add' is the dialog box is pointing to the DVD. That is incorrect but we see people trying that when they try to bypass the install and try to point only to the dvd, hoping they can play the ErgVideo from dvd without installing. We require the install to HDD, and then the dvd becomes your defacto backup that sees little use and little chance for wear and damage.

When it appears ErgVideo cannot find your CompuTrainer, generally you have done something wrong, misconfigured something, or there are broken wires. First verify that you are using FTDI-based USB-serial adapters. Instructions here.

Second, make sure the connections are per Racermate instructions from PC to handlebar unit. Be aware that you cannot run ErgVideo while other programs accessing the serial port are running. You must shut down rm1 or any other program that claims to 'speak' to the CT. 2 processes cannot access the same port. A bunch of people think ErgVideo must run with RM1 or other programs. That is false. You probably ran RacerMate One and ErgVideo together. After you do this and try to shut down RM1 to run ErgVideo correctly (on its own) a vestige of the RM1 MAY be stuck in memory preventing ErgVideo from accessing port until you reboot. (this doesn't happen on normal operation of either program, only when you mistakenly try to run them together).

Do this: Remove the USB-serial adapter. Reboot (full hardware reboot). When the pc comes back up, insert adapter and be sure the driver loads and it is FTDI. If it is anything else I can't help you. It is clearly stated on website that none other is supported. Check in the Windows device manager. If you see 'prolific' drivers assigned to ANY com port, I advise you to uninstall them. If your pc seems unreliable and you still get bluescreen crashes (ever), it's likely these prolific drivers. Thank me later. Anyway, once FTDI is verified, open ErgVideo (alone, no RM1) and be sure your options...general settings are set to scan for racermate devices (there are three choices: scan for ANT+ and Racermate, ANT+ Only, or Racermate only. Default is the first choice.). A scan will happen. The computrainer will appear in teh "trainers" list on the right side. You must assign it to a station with drag and drop. When all set, you MUST hit the okay button after assigning a port to a bike; hitting the red x in upper right is "cancel" and it will unassign your port. It works. It always does. Your problem is solved somewhere in the above, it always is. If you don't see the okay button in the lower right corner, configure your display to normal fonts so the window fits on your screen and you will see the okay button in lower right corner, or resize the window to bring it into view.

Update to the latest version. All panels are now scalable. ErgVideo requires a minimum resolution of 1280x768, when using font sizes "normal" in your display settings. Using larger font sizes can make screens larger but they may run out of space on your screen. Increase resolution or set font-size to "normal". ErgVideo 4 features fully scalable windows and controls. Grab the lower corner with your mouse and drag. It will work with all font settings available in Win 7, 8 and 10.
Update to the latest version. If the problem persists, please send the diagostic log to customer support.
Update to the latest version, and send us any diagnostic that is generated. Perhaps you probably did nothing, but your antivirus may have detected a false positive and is blocking ErgVideo from starting. This is most common with free anti virus like AVG (the worst offender), Kaspersky, Avast, PCTools and PCDoctor. We recommend that you install the most up-to-date version of ErgVideo software available at the downloads page. We recommend Microsoft Security Essentials as the catch all anti malware and virus detection package. It's built into windows 8 and 10 as windows defender, and it is all you need.

Update to the latest version. If the problem persists, please send us the diagnostic log generated. What follows is the old work-around that should not be necessary. If you read it and still need to try it after upgrading your software, please first save the diagnostic logs and send them to us, and let us know.

OLD WORKAROUND: You probably had a second screen connected via hdmi and you were running that window in full-screen mode. Then you disconnected the screen or had it turned-off when you ran ErgVideo again. ErgVideo wants reappear in the same state as last time, so you don't have to adjust your windows every time. When the second screen is missing, ErgVideo should come back on the main screen in the default size, but I've seen some cards not respond correctly. Definitely update your video card drivers from the manufacturer's website. That could fix it. Otherwise, some settings used to restore the environment to same state as before are making it crash, and it is because your second screen is now disabled, disconnected, or reconfigured in some way. Unfortunately just re-enabling it is not always possible (you have moved location) or even that doesn't cure it anymore.

So do this: 

  1. Show hidden files and folders in your windows explorer. 
  2. Now you can see hidden folder Documents\ErgVideo Data\Settings.
  3. Delete the file Documents\ErgVideo Data\Settings\ErgVideoUISettings.xml It will be recreated and set-up again with defaults. 

Next time you start ErgVideo, use the same multi-monitor configuration, or never use the maximized mode on an second screen. Just size the window almost the full size of the screen.

Dual layer DVD's are required for some titles, due to the file sizes of HD videos. If your DVD reader is not DL compatible, the DVD will appear to have no files on it and will not launch the installer. Insert the DVD into a very modern PC, looking for a small "DL" on the drive door. If you see the files in Windows Explorer, you know the DVD is not blank. you can get a compatible reader for less than $30 as an internal, and almost that same price for an external USB DVD reader/writer.

We don't ship on DVDs anymore.

DVD media and drives aren't created equal, and bad burns can happen. Even with good burns, some drives have trouble reading them. It's usually a firmware-matching-media issue. Every DVD that is sent out is verified in the burner that burned it, so chances are that when I get this dvd back, it will be readable in a machine here. But I would like to see and test it, ultimately, and maybe my blank-dvd supplier will have some answers or remedies. I have found laptops and xp-era machines to have the worst performance.

Before giving up, please do the following first:

  1. Use a very very very clean microfibre cloth like you (should) use on your riding glasses, and polish out any smudges such a fingerprints or any other substances that may be on the disk. Try to load again, this often works.
  2. If this doesn't work, and IF you have alternate dvd drives like externals or drives on another machine, you can try it (don't do a full install, we don't license multiple machines). Just copy the files in the (insert video name here) folder to a shared folder accessible from your target machine on your network, or copy the files onto a USB thumb drive if you have one large enough. If it succeeds you could then transfer over your network or the thumb drive to the target pc that you would like to license. I can give you further instructions on where to copy the files to if you choose to take this route. This often shows that the disk is actually "good for some"with some error that a particular reader drive can't overcome. Every disk returned to me so far has been readable in all of my PC's here.

We don't ship on DVDs anymore, and haven't for a long time. If you have stored your DVD and are loading from them again as from backup, be aware that they can degrade in storage due to temperature and humidity. We have divested our burning infrastructure and cannot replace your DVD's. Getting a new download for files is not free. ErgVideo does not provide a free backup service.

You may not have let the installation complete, or more likely you had ErgVideo running while you were installing a video. Our installer assumes you are not running ErgVideo at all, since that's the case for a new user. Open ErgVideo, click Options...library and training plans tab, and click Add. Navigate the filedialog and point to the place on HDD or SSD where you installed the ErgVideo. DO NOT POINT TO THE FILES ON THE DVD drive. This will not work (by design) since your dvd's will wear out and degrade if we allowed regular playback from DVD. Select the .evr file and click open. If your ErgVideo is still locked, you will be presented with the unlock page. Unlock or cancel to see the 5 minute preview and unlock later.
The server is randomly checked for available updates, and this would reveal the button if your libraries were incomplete. To manually add the workouts, click Options...Library and training plans...update workouts. You must be connected to the internet for this to work. If you are not connected, the supplemental workouts are not available to you.

Update to the latest version. You are not up to date by a long shot.

ErgVideo displays 'update available' when there is an update available and this should not be ignored. Anytime you have any problem at all, you should always do a windows update, update your video card drivers, and look for an update to ErgVideo at the website.

In this case you should open a separate browser and go to the website, since launching the update from the red 'update available' button in ErgVideo will likely trigger the same browser-launch error when opening IE.

Update to the latest version. This has been fixed years ago, you have not been updating and enjoying the many new features of ErgVideo. This problem is resolved simply by updating your software to the lateset available on the "downloads and updates" page.
