Hello, since it is quite uncommon to have faces with 256 resolution (or more), why not use this algorythm on 128 res faces, and then convert and merge into a video as usual ?
It is far from my knowledge to use it and integrate it into DFL, but I'm currently using JavPlayer, a program to decensor mosaic in japanese porn, which uses TecoGAN successfully. From what I understand it can boost resolution of anything up to 4x, and it would be way faster than training a real 256 or 512 model. From my experience with decensoring japanese porn, using this for deepfakes would take the normal amount of computing time + more or less 20%.
To be clear, contrary to the Topaz AI gigapixel method, we would use this only on faces (like JavPlayer uses it only on the mosaic censored part of a video) and not the entire video. That's why it doesn't take much time. Only after the TecoGAN upscaling is done, the final video would be created.
So if someone can inform the maker of DFL about it, I think it could be awesome. Or maybe there's already something like this in the latest version, I haven't tried DFL since 6 months.
