I have a 1080p quality mp4, I want to take a part of it to make into a loop, but I don't want to lose quality, and I tried to make a webm , set high quality and CRF and tolerance to 0 and the result "seems fine" but it's more than 200mb, when the original video was 5 minutes and just had100mb.
Are there good ways to have a precise edition of a video, keeping the quality, and not taking lots of space. If possible also being able to edit by frames, because I want to make other loops but seeing the ratio of my first attempt compared tot he original, I'll run out of space before I finish.
