Very impressive. Significantly better than the image manipulator tools previously available.
I’ve experimented with Pinokio before, mostly for deepfakes, and the applications on there had a hard time with certain lighting conditions and facial distances from the camera in movies. For example, I tried replacing Rey’s father’s face with a young Ian McDiarmid, and it didn’t work very well in the scene where he’s on Ochi’s ship. Mostly due to the lighting, but also because he’s pretty far from the camera. I wouldn’t be surprised if the same limitations apply here.
I feel like that would work more effectively with EbSynth or something like that, but basically doing a face-swap composite first then using EbSynth.
