[BUG] Generated movie cannot be played / file is corrupted

[juhamust]

Describe the bug
The recorded time-lapse video cannot be played. I've tried both .mov and .mp4 files with multiple players (QuickTime, IINA, and ffmpeg), but none of them can play the file.

When analysing the file with file command:

file display2-2026-03-22_11-31-30.mp4
> display2-2026-03-22_11-31-30.mp4: ISO Media, MP4 v2 [ISO 14496-14]

To Reproduce
Steps to reproduce the behavior:

1. Record timelapse
2. Play the video

Screenshots
If applicable, add screenshots to help explain your problem.

+1: Sometimes this also occurs with camera recordings too.

Noticing that shorter timelapse recordings are likely to not be corrupted, whereas longer ones (I did about an hour) get corrupted.

Did you find a quick fix? since it seems that the files are still taking quite a bit of storage.

No idea what is causing this, but untrunc was able to recover in seconds.
