I've been having issues with the playback and export of my video glitching out (the video I'm editing is not even a minute long). On my old Macbook the solution was always to just switch the Video rendering and playback render option from Mercury Playback Engine CPU to another one. But I can't even change the render option because it's greyed out, and stuck on the Mercury Playback Engine CPU Acceleration (Metal) one.
I've done my best to dig around to find what else I can do, I've reinstalled Premiere Pro, and I've found that I have a newer graphics chip - the M1 Chip which you guys have been working on to make Adobe apps compatible with n everything? Is this something that isn't quite working yet? Or am I missing something else that I'm meant to do to fix this.
That it's a QujckTime movie file isn't enough. It has to be a QuickTime movie file that is supported directly in After Effects since Apple discontinued QuickTime as a system driver for time based media.
