I have found a few weird .mp4 files circulating, mostly on discord, that act funky when played. I found one a while ago that was 20 gigs and i could post it on discord, which somehow got around their file size limit, the same video also somehow played forever. I recently found another that would timeout and crash any application i tried to play it in (discord, chrome, windows media player). I think these are really interesting and would love to learn more about them. If any of you have an answer or know where to point to find one, i would really appreciate it! thanks!
