MacBook Pro M1 Max iPhone 4k footage glitchy - becoming impossible to edit
I have a fully-maxed out Macbook Pro M1 Max 16 inch with 58 out of 64gb ram dedicated to premiere pro and 1.5TB internal space left. I've even created low res proxies of all the media I'm currently editing.
Regular editing has become impossible because the video freezes after a few seconds in every time I press play in the monitor, but the audio keeps going. When I first got the computer 7 months ago, I don't remember it having any of these issues. I had no problems running in full 4k switching betwen angles.
When encoding it goes super fast, but at first it seems like it's having trouble loading the media, which doesn't make sense considering it's all flash. A few times it has shown media pending as well.
I've tried runniung in Rosetta, no difference. The proxies helped a little, but still it's almost just as bad. I don't know what to do. I'm only editing with 2 stacked video clips in the timeline. I didn't even film with Pro Res. It doesn't make any sense.
Can someone please help me figure out why this is happening and how to fix this?
