I was messing around and made this video for fun. The goal was like code golf ( https://en.wikipedia.org/wiki/Code_golf ): make a video which clearly depicts something and has a filesize of less than 100 kilobytes. I did it thanks to MP4 and not GIF: ~10x filesize difference for the same video. I could have used Floyd-Steinberg dithering, but regrettably didn't.

Steps:
1. Have some stupid video.
2. FFmpeg: screenshot every 0.1 seconds, saving each one to a file (ffmpeg -i vid.mp4 -vf "fps=10" output_%03d.png)
3. GIMP: open image, open images as layers, delete layers, crop, make 256-colors palette and apply it, various editing. Save as animated GIF.
4. FFmpeg: convert to MP4 (ffmpeg -i vid.gif output.mp4)

Not hard to do, just a sort of fun creative thing. Here's the final MP4 file in Arweave forever (text on front side of paper, nothing on the back):
