I recently took delivery of a MacBook Pro M1 Pro, and went along with installing the usual suite of Adobe applications I use daily... I started editing a video project I had been working on and noticed that when I came to export the sequence how I normally would for Youtube (choosing Youtube 1080p preset with hardware encoding) and adding to the media encoder queue the exported file was really low quality - blurry and pixelated compared to the original media. I also noticed that the file size was over half of what Premiere Pro had estimated it to be. If I export with software encoding instead the file is 'normal' quality and matches the estimated file size from the export window in Premiere Pro.
I spent the afternoon playing around trying to figure out what is going on but this seems like a fault/error. I exported the exact same project using my Windows desktop computer using the exact same method with hardware encoding and another version with software encoding and both versions exported on Windows matched the file size and were of 'normal' quality. This seems like a M1 Pro issue?
I've attached a couple of screenshots of example exports - I'm pulling my hair out with this and hope someone is able to shed some light on it. Is it normal for hardware encoding on an M1/M1 Pro/M1 Max chip to have this effect, I was wondering if it could be more efficient at compressing or something?!
Also Premiere Pro on M1 Pro MacBook completely crashes and grinds to a halt if I add any After Effects composition to the sequence. Maybe my MacBook has faulty hardware but everything else I use (non-Adobe) is fine with no issues.
