Description laqco.spammoq 2021-02-07 10:36:48 UTC

SUMMARY
When I edit recordings kdenlive works just fine until a certain timestamp in the original video file.
(when i had a 12mb bitrate it was about 25 min; with a 24mb bitrate it is at about 12 min)

From that point on the video and the audio both stutter and do weird things; I think the audio seems sped up and the Video does sometimes too.

STEPS TO REPRODUCE
1. Use kdenlive 20.12.0.
2. Import large video files.
3. Try editing/previewing the video.

OBSERVED RESULT
At a certain point the video and audio do weird things.

EXPECTED RESULT
Everything should work just fine.

Could be similar to this Bug 432623 or this Bug 432668. Maybe the some connection to Windows playback is not proper integrated.

seems the same as #432668 - i tried the fix but it didn't work

I think this is a kdenlive-coded problem...
