4k Capture again broken, file corrupt by 22 sec Xbox One Preview Update 10.0.19041.3011

Hey, thank you for your reply.Everything you said is 100% correct.

After that issue with 4K capture started I entered in
insider program, and true insider update from 29.5 (2006.200527-0000)

is fixed that issue and 4K capture was worked just perfect and better than ever I would say.
And then a few days later we get new update

and we are at the same problem again (corrupt 22 sec file) already well known issue...

Let's hope is true that alpha skip-ahead
fixed the issue with new update because that means we can
expect updates a few days later for omega, beta&delta rings.

All the best!

Same problem here.

Two different Xbox, different USB 3.1 sticks and same result.

4k capture are corrupted after 2 sec.

The funny part is this was working really well before they updated the way we capture gameplay.

4K Capture is is broken after last update (15.5) we are waiting for new update with fix for that issue.

There are a lot of people with exactly the same problem 4K Capture stops
automatically after 23-24sec and that file is corrupted,
this problem started after the last update (15.5).

Hey, you're not alone. I'm in the insider preview OS program, and this problem was fixed in a late-May update. Then it was broken again in a June 2 or 3 update (mandatory). The public version of the OS also is still broken for 4k HDR/SDR capture, so we're
stuck in the water here.

Best info I have for you is "they're aware of the issue and are investigating". But it really sucks because there's no other way to get decent 4k footage without paying for a $400 buggy capture card. A recent alpha skip-ahead update reportedly fixed the
issue, but I haven't been able to contact any on the subreddit that got ahold of that update to confirm.

The 1080p/30fps SDR is garbage, with a terrible bitrate and subpar HDR->SDR conversion. All I can suggest is to get in the insider program through the hub and hope that you can get an update that fixes it.
