This would be cool but I doubt it could be done 100% convincingly. Deepfakes can be uncanny but you can usually see the seams.
True, true, true. It would surely take significant effort for what amounts to only a few seconds of footage. I really only threw it out there with the hope that some deepfake expert might see it and be all like, “oh yeah, I can do that no problem!” It’s weird how I’ve seen such impressive examples of deepfakes while others really don’t hit the mark.
