Looks great. How are you encoding the video into MP4? Ffmpeg with wasm? Or WebCodecs?
I’ve struggled to find a pure client-side encoder that is as fast, lightweight and high quality (in terms of lossiness) as what I had going with mp4-h264[1]. I suspended the project out of legal concern but it seems like the patents are finally starting to run their course, and it might be worth exploring it again. I’ve been able to use it to stream massive 8k near-pixel-perfect MP4s for generative art (where quality is more important than file size), compared to WebCodecs which always left me with a too-lossy result.
Thanks! We're using a server side ffmpeg process for the encoding right now, so running a server is required for rendering. We are exploring fully client-side rendering too but I'm hesitant to use WebCodecs because of the limited compatibility with many browsers. Ffmpeg-Wasm does look promising so I'll give that a closer look very soon. I'll also check out your project, thanks for sharing.
