Here are some of the frames I could see by pausing but it only lasts for like a second https://imgur.com/a/FXWxWbK along with some audio that sounds like a male voice saying "do what" As to the how one of the things I like to do as a weird hobby is look at random data that's been added onto the end of files. I've got a python script that can scan pictures and saves any data that's been appended to the end of jpg png or gif files. Most of the time it's boring but sometimes I find artists comments, meme copy pasta, and other oddities like https://e621.net/tickets/47183 way back when people use to add random files to stuff. thankfully that's not much of an issue anymore.

That is wonderful and you're wonderful for doing this.
As for the video on that one post, I assume it's just something that was overwritten in a weird way. Hard drives are very strange in how they work...
