VFX artist and developer here, who's deep into this stuff, and it is really not there. It's an island of itself, barely controllable and barely usable with other media. They are just now getting around to generating alpha channels, with virtual none of the existing pipelines for any AI video or image generation tools to even incorporate and work with alpha channels. This is just one of several hundred aspects of incompatibility. It really seriously appears as of no one at any of the AI video generation research teams has any professional media production experience, or even bothered too look at existing media production data standards, and what they are making tool-wise is incompatible in every possible respect.
