I like this idea, and, I don't dislike the AI-targeting aspect of it, but I also think we should disclose real actors, too. Like they deserve to be credited. One thing I like about a lot of Japanese music videos is, they credit the people in them. Not all of them do it and I'm not sure if it's required, but some of them do.

Like this: https://www.youtube.com/watch?v=1Epuw7MG0a8 (skip to 3:20 if you don't care about hard rock in Japanese). First they credit the actual performers... and then they credit all the extras. Then they credit the crew who worked behind the scenes. They even have special thanks.

Maybe ads don't have the run-time of music videos, but I'm also all for making ads shorter under the legitimate guise of crediting the people who made the video.
