Creating Sprite-Based Cutscenes (For AKIRA)

[Chris2Balls [:B]]

Considering that this is based off the film, I think they probably used footage from that, reduced it, and polished it.
If you want something close to these, that's what my approach would be!

So yeah, I'd make a few screen caps, reduce their size, then colour reduce them using a Genesis palette (you have to work with indexed colours rather than 24bit RGB), and then clean the result so it's not too grainy.
