What compressing MP4 actually does
Compressing MP4 means re-encoding the video inside with a modern codec at a quality you choose: low, medium or high. Camera footage typically gives up 30–70% of its size before quality visibly suffers, and screen recordings squeeze even harder. MP4 runs roughly 50–100 MB per minute at 1080p, depending on bitrate, so there's usually plenty to give.
