rippling lines that you often find with AI animation. I couldn't determine for certain whether it uses AI - maybe there's some other technique causing that creepy rippling effect - but I decided not to post it when I ran across it a while back.
The original video is so much nicer, and it was restored in 2020. That video, and an article about it:

This new 4K version of the original promo video has been painstakingly and expertly restored from a recently discovered rare copy of the original film for I Believe In Father Christmas which was shot partly on the Sinai Peninsula of Egypt and in the caves where the Dead Sea Scrolls were discovered. The video includes previously unseen footage from the Vietnam War and was directed by Arnould Schwartzman who went on to win an Oscar in 1982 for his film Genocide.
The new video restoration included manually cleaning the film to remove the sticky residue from the sellotape joins to allow it to pass freely through the scanner, rebuilding the cuts to remove the jumps, recreating damaged frames based on those surrounding it, frame by frame dirt and scratch clean and eve repainting in camel legs!
