This is the direction i've been theoretically harping about to all my friends, API first creative software will win out. After Effects has a decent JS api, Da Vinci Resolve has python and lua, you can script your way to a decent starting point with any of these tools. They even have well featured rollback for transactions committed during scripting. We need a generic MCP for the scripting environments in many desktop apps, screen capture for ones which take multimodal input.
