There is someone who has taken a lot of old films and used AI to colorize them badly and "boosted" the frame rate from 24 to 60fps and then uploaded this trash to the Internet Archive.
I hate this. Films shot in b&w have an aesthetic that is destroyed by colorizing them. Video games might look better with more frames per second but movies don't. We didn't accidentally settle on 24fps, it was trial and error. A film shot in 60fps looks bad. A movie that has been artificially "boosted" to 60fps is an abomination and should be destroyed.
