Given that my laserdisc rip is made with poor quality equipment, I think I’d rather hold out for a better source than that before trying to despecialize Mewtwo Strikes Back… as big as the difference would be between a 1080p and 372i source, that would be exacerbated by a cheap laserdisc player and a bottom-of-the-line DVD recorder. 😦
Completely off topic for this thread as a whole but there are some really good avisynth scripts for upscaling specifically anime, which is a totally different beast from upscaling live action footage and can actually have worthwhile results.
