This is super cool! We built something in the same vein but using Mux as a way to dog food our products[1]. This is certainly doing more product-wise, though in terms of being similar shape-wise to Loom.

I noticed your demo example in your top comment isn’t working, which made me suspect you’re just using the raw MediaRecorder output, and sure enough. Unfortunately…that’s just not going to work for any “real” use case.

MediaRecorder is well known in the video infra world as being incredibly crappy videos, to the point of being difficult to transcode reliably much less just use directly as a video for playback. Sorry to be the bearer of bad news, but there’s just no way of avoiding a proper transcode (if you care about the videos created from any supported browser being playable on the gamut of browsers).
