Do you mean you want to move a motor based on the position of the head of a person in the video?

Do you have an algorithm/ai routine that interprets videos and generates values according to the video feed ?

I'd love to see how a flat 2d video could generate meaningful servo actions for (I assume) some kind of "added environmental feedback" during playback?

I personally think you would need an "automation track" (like in most modern DAWs ) that simply plays alongside the video.
