As the title implies, I took a raw video at 1440x602 at 12fps (most stable 2.39 resolution - no skipped frames). Brought into After Effects and exported as a ProRes422 video (also upscaled it to 2K wide for the lulz ~142% upscale). After Effects automatically interpreted it as a 24p clip, so I was left with a video at 2X speed. So I dumped the clip into Premiere and sped it down to 50%. Then I slowed it down to 50% using Twixtor in Final Cut (I don't know how to use Twixtor well at all, set speed to 50% and made the clip 2x as long). Then export and bring into Premiere to compare.
To my eyes (very tired eyes at the moment), it looks a lot better than the 12fps clip (unless I made that worse but I figure the 50% slow down should work fine, Premiere always handles 60p footage extremely well when slowed to 40% on a 24p timeline).
The resolution looks really nice at 1440x602, although the noise levels are pretty ugly (ISO 1600). The 50D noise test I saw at 12,800 is what I'd like.
