Curious how you're handling the MP4 export entirely client-side — are you using FFmpeg compiled to WebAssembly, or something custom built around the WebCodecs API?

So FFmpeg is part of the website in general but it is not used in the editor itself. I did built on top of the Video Codec APIs and ofc a muxer library like mp4box.js
