it's just corruption. due to the way video compression works, if part of a frame gets corrupted, you end up with weird patterns like this. it might last a few frames also.

This looks like .jpeg corruption to me. It does happen on some video because it uses jpeg compression for frames, but the compression methods that utilize motion data corrupt differently and look more like this:

Also, attached is a corrupted .jpg file. I cut some parts of the file out, and you can see how the pattern resembles the one in >>358547 and in the op.
If someone has a Manx-cirno, please post. I accidentally wrote over mine when making this.
