Here’s another AI tool: LivePortrait. It lets you drive a source video using a driving video. In this example, I use a 3D animation as the source and drive its head movement, eyes, and mouth with a video of Ashley Judd. Both videos have the same number of frames. The 3D video’s angle isn’t identical by design, so it’s not a perfect match — but it effectively conveys the concept.
Edit: I just noticed the hair shifts slightly due to the AI adjustment. That can be fixed with masking — I’ll check it out later, just out of curiosity..
