@randomeizer - We should have a proper play with this at some point. I think if we exposed a way for CommandPost to import/export an FCPXML, then that would open up a HEAP of automation possibilities. We could even potentially make a Lua wrapper for FCPXMLKit?

[randomeizer]

That would be one way, although I still like the idea of exposing the Actions API. Would allow an AI to control the app in real time, which could be interesting.

But yes, Codex might be more capable of helping build something at this point. I did try with Copilot a while back, and it didn't get far.

We can do both... I'll try have a play at merging this in later this week.
