The video function is enabled in the Zwift game on my PC (Win11 Home - Ryzen 7) and the button is also active in the game. Clicking the button creates an mp4 file of 0KB in size (in the Zwift folder on my PC).
Obviously a file with no content will not launch.
What could be wrong?
Exactly the same problem on Win11 Home Ryzen 7. Was there any resolution to this?
Hi @Dave_Brodmann_TFC, thank you for posting! I’m Gian from Zwift.
I’m sorry to hear that video screenshots aren’t working for you. After looking at your app sessions, it seems this may be related to a setting on your computer. Does running the app as an administrator change anything?
Hello. I just right clicked Zwift and selected “Run as administrator”, and answered yes to the box that pops up asking if I really want to allow zwiftlauncher.exe to run as admin. The results were the same though, 0 byte files are created in the videos/zwift folder.
Hi @Gian and @Dave_Brodmann_TFC
I have also tried to run as administrator withe the same result 0 byte video files. Only the photo function is still working
@Gian @Uwe_Knoll it’s odd that the video’s were working for me until 13 February, but since then it just creates a zero byte. After todays ride I looked in the zwift log file and saw this line:
[12:47:54] ERROR LEVEL: VIDEO_CAPTURE : WindowsFailure, 2 of 10, reasons=[“SaveMovieWriter: CreateSinkWriter failed”, “SaveMovie: reader or writer failed”, “Encoder: SaveMovie failed”, “VCW_StateMachine: Encoder failed”]
13 February appears to be the start of the 1.58 release rollout
I have a brand new Dell Core I5 12nd gen running with Windows 11. When I try to record the video I see a mp4 file inside Zwift video folder but the file has 0kb and can’t be opened by any player. At the end of the game no video is available for upload. The video button works perfectly and behaves as expected but no actual video recorded. Please, could you help me? Thanks.
This weekend I discovered that when I try to capture a video screenshot on Windows using F9 the file that is created is zero bytes (empty).
This has always worked before Saturday (11/23/24) and the problem has persisted through Monday.
The only thing that has changed is that there was a Windows 11 update that I installed after the last time I used Zwift on Thursday.
Regular screenshots (not video) continue to work, it’s just video screenshots that have stopped working.
Has anyone else updated Windows 11 Home recently and had a similar issue?
I’ve attached photos of the build information for Windows and Zwift.
Thanks!
As a followup, tonight I tried uninstalling Zwift, rebooting, and reinstalling, but the problem still persists.
The computer is a dedicated cycling computer and Zwift has been running without a single problem for over a year, so I suspect that the Windows update did something that prevents Zwift from successfully performing a video screenshot capture.
Yes there are several other reports of this. No solutions AFAIK.
Im zwifting on a pc with windows11. In settings i have video screenshot enabled but every time i finosh a race or workout it took pictures but not 1 videoscreenshot to choose from.
How is that possible? My pc is a gaming pc so i doubt it has to do with the spec although im not sure ofc
It is a photo taht is taken from zwift game, not a video.
If you want a video, take it with you smartphone pointing to the screen.
If you are to dumb pls dont answer. Zwift take videps as well
Good lord. Zwift automaticly takes videps and photos. Photos are working fine but zwift dont take a video
There have been reports of Windows machines failing to record video screenshots recently. It results in a 0 byte video file. Is that what you’re seeing? I don’t think anyone has found a solution for that.
If you’re using Windows N or KN editions, you will need to install Microsoft’s media components that are not included in these editions by default. If you do not install these components, you will not see the Video Screenshots feature even if you have an eligible device. See Microsoft’s support site for details.
Could this be a reason?
yes, I see a 0 byte video screenshot saved in my Zwift video folder on my PC.
I also checked the activity *.fit file with zwiftalizer & see the video screenshot feature disabled although i have it enabled in-game.
The Zwift Help Desk have advised their engineers are aware of this issue & working on a solution to be released with a future game update.
I have the same problem since a few days.
Windows App
+1 here, since upgrading to Windows 11 Pro 24H2.
Video screen shots, which had previously been automatically captured, simply stopped being produced. I checked settings and they were enabled. I toggled off and back on again. Still no video screenshots since the upgrade.
I have not tried a manual video screenshot. I’m not that fussed about them. But their absence is quite evident.
Oh, and FWIW, I’m using an Asus ROG Flow X16 laptop with i9-13900H, RTX 4070, 32GB, 1TB SSD. Plenty of free storage space. No other games, just Office and browsers.
