I wonder what percentage of the population edits video on their computer. I don’t but I have no idea if I’m just weird or something.
Probably not that many, but the parent post to mine specifically mentioned editing iPhone footage.
A lot of people editing iPhone footage are going to use a phone-native app like CapCut, but even with that coping with the horribly inefficient compression of h.264 and h.265 footage gets them up to egg-frying temperature very quickly.
It saves footage in a very inefficient format which is horrible to edit with, so it'll be slow and clunky on anything.
