Video processor like Deep Fake?

Question

Artificial intelligence

A video handler is required, where in real time you can change the face on command.
For example, there is an hour video. Where do we replace the face. And during a LIVE show, through certain commands, you need the ability to change. Conditionally to put a smile on your face. Are there ready-made solutions? Or where to look for a developer, programming language area, etc.
