Same for me, video capture used to work, now only photo’s get saved and get 0 bytes mp4 video files.
I’m following this with interest as I have the same problem . The video clips use to make ideal “Reels” on FB in the past .

I recently upgraded my Zwift PC and am now running Windows 11 Home, version 24H2 on a PC that supports the Zwift video capturing. However, the video clips that are saved have zero size or content. I have checked my Zwift settings and all looks good. I have opened a Zwift support ticket but I have just gotten bounced around and have had no progress on a resolution. Does anyone have any resolution suggestions? Thanks
The Zwift log file shows the following error.
[5:43:49] Got Notable Moment: NEW PR!

This problem is the result of the last Windows update. I reported the problem 2 months ago and Zwift just recently acknowledged the reports people have been making since. Hopefully that means they are finally looking into the issue, but I suspect that they don’t have a lot of development resources so who knows when we might have a resolution (and it’s possible that it’s a Windows bug that Microsoft will have to fix).

I’m having this issue, too! Started after Dec. 20th for me (which is the very day I updated to Windows 11, version 24H2. I probably rode first and updated the computer later in the evening). I have a HP Pavilion gaming laptop with AMD RIZEN 7. The videos are 0 bytes on my computer and don’t show up at all on my phone, even though I do video capture through the button on the companion app while riding. Won some epic sprints today and quite gutted to not have the footage to relive it and show it off on Strava! 
P.S. My Zwift is updated to the most recent version: v 1.81.2

I have the same issue. It says the file is corrupt or what not, but the files shows no data.

Hey Evan, any update on the Windows 11 video capturing problem resolution?
Thanks
No updates to share just yet, but we’re looking into it and we have one employee who is able to reproduce the issue which is helpful. We’ll share back here when we have more.

I also have the same issue after the latest Win11 update. Thought it was just me until I found myself here!

I’ve had the same problem since Jan 5th '25. Its a high spec PC only a year old, video screenshots are enabled, prefs.xml shows it as enabled, but the Zwift Videos are stored on the Zwift Videos folder as 0kb files. It seems to have started since the following was applied on Jan 4th - 2024-11 Cumulative Update Preview for .NET Framework 3.5 and 4.8.1 for Windows 11, version 24H2 for x64
Thanks!
