Show HN: Compress videos by up to 60%

On both Firefox and Chrome, when I hover over either of the videos, the thin dividing line disappears, and it's not clear which video I'm looking at. Albeit they are "supposed to" look very similar, I still don't know whether I'm watching the original or the compressed one.

Typically in similar sites, I've seen a draggable divider that lets the user specify how to horizontally divide the frame between the two comparable videos.

Do you process an included audio track as well?

Compressify's developer here. Would love any feedback on the site and video results. Sorry if the server is slow, it's getting the product hunt hug of death.
