Built a browser-based FFmpeg editor that runs entirely client-side via WebAssembly. Your files never leave your device -- all processing happens in a Web Worker. Works offline as an installable PWA after first load.
Note those only apply to scene_sad which is used for scene change detection and freeze detection and a few other things like mpdecimate -- it's a very specific use case

Just a thought - is the text “Click to upload” with a cloud icon perhaps a bit misleading?
If it’s fully client side, then you are just opening a file in essence - no clouds in sight!

I agree something like a folder or file icon would be more accurate.

I guess UI-wise some changes wouldn't be bad, but I am
just glad it works. I am currently converting an ancient
.mpg into a .mp4; I could do so via ffmpeg from the
commandline, but I always forget which options to use,
so a GUI kind of frees brain space here.

Nice interface at a first glance, for sure can be useful for users who would find using the actual thing too cumbersome. How does performance compare to the native app? Is any form of hardware decoding/encoding like h264_nvenc available? (I guess not?)

I would imagine the only way to use NVENC directly from a browser would be via WebCodecs.

This is dope. Made a PR.

this is ffmpeg running inside the browser am I correct? did not know this was possible. wonder what else we can run via webassembly

vibe-coded, and the github repo does not even contain the sources, just a single 'server.js' that is only for the documentation

Interesting idea - must have been a lot of work to add
all those features. I just tried it and it works locally
too, which is pretty epic.
