I remembered that WASM application cannot use any kind of hardware acceleration. So have anyone tested the website for large videos?

Definitely a performance hit! Probably a combination of the lack of hardware acceleration and running in a JS virtual machine.

I haven't checked the exact hit, but that's mostly because our focus for this tool was on people who would never touch ffmpeg or a command line.

Also, the alternative for us would've been to upload remotely and run on Lambda or similar, which I think would lack hardware acceleration as well.
