Yes, exactly! We're also big fans of the generator function model.
In Remotion, you get the current frame of the animation through a React hook called useCurrentFrame(). You then use React to build the UI based on the return value of the hook.
By structuring it as a generator function, later parts of the function are for later parts of the animation, which makes it a bit easier to read and write. We found this to be a little more intuitive. Ultimately it probably comes down to personal preference.
How does this compare to Remotion^ which uses "React" mental model?
