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 :)
