There is movement in those frames, so there should be vectors which can be copied. If I skip ahead in those videos I get weird colours but that's it. When I try to datamosh the video by duplicating p frames it either freezes or just plays slower in those segments. I also tried removing the b frames with ffmpeg but that didn't work either.

In fact except the first i frame p and b frames are alternating most of the time. I saw there are a lot of b frames in there.

I looked at it in avidemux 2.5.6 and tried duplicating p-frames there manually, but that also did not work. It worked with an example video I got from the Internet but it does not work with a video I exported from blender.

I tried p Frame duplication via an aviglitch script.
