Bug: 33% frames lost when rendering videos recorded from OBS (VFR)
I've been using HitFilm for several months; I'm now on version 15.2.10619.40501 and there's a bug that keeps happening and greatly reduces the quality of my renders:
1 out of every 3 frames is lost when decoding a source video, turning my smooth 60-fps original recordings into stuttery 40-fps videos. This happens on every single video if I:
- record with OBS (settings in the .png attachment)
- remux the .flv file into an .mp4 file with OBS
- open a project with that resulting .mp4 file (sample .mp4 file in the .zip attachment)
I know that if I re-encode the .mp4 file using avidemux into a new .mp4, the problem is solved... but only for the first 1h30mins of the video. After that time mark, 1/3rd of frames are still lost. Plus this takes a very long time to do, especially on 2h+ videos .
I believe this is a decoding problem, because the problem also happens in the HitFilm "Viewer" Window, and can be easily spotted by advancing the video frame by frame (shortcut: "." in HitFilm, "e" in VLC).
This severely hinders my ability to put out videos; especially long ones. I have tried many workarounds and none of them seem to work effectively. I'm reaching the point where I'm considering stop using HitFilm and going for other applications instead. I don't really want it to come to that, instead, I would love to see this fixed in HitFilm.
What more can I do to help you folks fix this bug?
