iMovie file exports are massive
Yes, there are a lot of questions and answers that I found about this - both here and by googling. Generally, the answers are long lectures about how file size is determined by compression, video quality, length, etc... I understand all of that. But there must be some simple way of fixing this problem.
I have a file of a zoom. it's over an hour long, 1680x1050, H.264. It's 164MB.
I want to trim it down to make it shorter. I import it into iMovie (10.1.14, running on my MBP with OS 10.14.6). I cut out half of the video. I export it as 1080p, low resolution. The resulting file is over 860 MB.
So I would like to use iMovie because there are a few specific edits that I need, but mainly I'm throwing away half of the data. Why is there no way of saving it, with those edits, without massively increasing the file size?
