That's more than I expected from them, genuinely. But it still doesn't seem like a very solid solution. I wonder how much variation in look and voice it accepts? My partner likes to cosplay, and some of the costumes are quite extensive. If they want to generate a video in a specific outfit will they need to record a new source video? The problem exists in the other direction, too. If someone looks a lot like Harrison Ford, will they be able to create videos with their own likeness? I wonder how this extends to videos with multiple people, as well. E.g. if both my friend and I want to be in a video together.
