Good point. I agree that could be a very interesting direction.

I have used Remotion for years because the DX is great, but the performance and overhead is significant. Even something like attaching subtitles to a video can take around 10x more time and resources than bare FFmpeg because of the chromium layer.

A headless version of this wgpu renderer with a clean API and eventually a nicer DX layer such as a react renderer could be a strong replacement for that kind of workflow.
