For Leia and Tarkin, they spent a lot more time and money doing 3D meshes of the original actors, then applied those meshes to the new actors. The textures looked great, but they suffered from the "white dots" approach of current motion capture, where a lot of the typical human facial movements are either lost, or are smoothed out to the point of having that swooshy 3D keyframe look. Actually the YouTuber posted earlier tried deepfakes on Leia and Tarkin, with not-bad results. The animation is still bad because it's based on the CG source material. It'd be interesting to see the results if you could directly process the raw footage of the new actor, rather than the final footage we saw in Rogue One:That's odd. A user on YouTube suspected that they used DeepFake for Luke, note how "flat" Luke's face looked in comparison to the 3D rendered Tarkin and Leia in Rogue One. Does anyone know for sure if Deep Fake was used or if the previous 3D was?
so they need software that can handle working with the file sizes needed for 4K video.
I think the software could probably handle 4K if you have enough VRAM, but that's easily solved by spending a lot of money.
