When I work with 4k footage, I like to create proxies. But since I'm on windows (was on Mac before), it's hard to work with.
I have to transcode mp4 to Quicktime everytime and it takes a ton of space. When I create prores or cineform proxies on my mp4 videos, the playback stutters A LOT. Sometimes the video doesn't play at all.
When I try editing with mp4 without proxies it's a nightmare. And I don't want to transcode everytime because when I have a lot of clips it takes too much space.
