Help repairing a glitch in a video

[highpitch]

Hey guys, can someone please do me a favor and help me? I need to repair this free to use video, specifically a segment from 00:21-00:25 mark. It's all glitchy and unusable. Can someone who knows how to use ai tools please try to fix it. I've contacted the original uploader, but unfortunately they don't have the original project anymore..

I'd be very grateful.
Thank you very much in advance!

To be frank, I instead recommend learning Blender to create an asteroid field (https://www.youtube.com/watch?v=IDlNRBJTisU) or asking someone who uses Blender to do it.

I doubt you can 'fix' this, aside from: extracting the last non-problematic frame 649 and the first-non problematic frame 751, use something like ComfyUI to generate a video with a length of 101 frames between those two frames and then replace the broken section with the generated one. But that will require some fast hardware, basic video editing skills and probably quite a bit of hdd space,...
=> learning how to create such a video might be a better goal.

Hmmm ... you might be able to "fix" this using motion estimation because this is a classic "pathological case" which is completely different from a normal "organic" video. Every object is moving in a constant motion and is enlarging in a predictable manner. If you can get a motion estimation algorithm to use a few keyframes from the first and last segments, you ought to get very good results in the middle of the video. The left and right sides might need some cropping or other types of fixing, but the center might be almost perfect.

I've queued up a film transfer I did about fifteen years ago to a train approaching a station in Lund, Utah. There were all sorts of splices in this section and, with motion estimation, I was able to make the video look perfect. If you think about the video mechanics of how that train advances towards the viewer, it is almost identical to your asteroids.
