Show HN: WebAssembly and ffmpeg = Quick clip, overlay, resize and GIF-ize videos

The main reason why I use ffmpeg/edit videos is to take my 3440x1440 screen recordings and crop+resize them in a format friendly for twitter, otherwise twitter will do its own (additional?) resizing and compression which just destroys videos

Sorry for not responding sooner.

That sounds like a great use case for us to handle! Although I think ffmpeg in the browser loses some efficiency over the command line.

I think we added cropping as a possible future feature. I'll bet ffmpeg makes that really easy to do.

I think we should also work on optimizing the output size. I think we use a pretty high (err, low) -crf, which can result in ridiculous file sizes.

Thanks for the comment! Appreciate hearing use cases :)
