Looking for CLI tool to replace video background (AI prefered)

Hey guys,

I’m looking for something similar to FFmpeg, but then for replacing video backgrounds using AI.

Preferably something I can run from the command line and use in scripts/batch. Quality matters, especially around edges and hair.

Anyone here using something like this or knows a good setup?
Thanks in advance.

which background type do you want to replace ? a background from other video, or a fixed config background, or a random background generated by AI via a text prompt ?
