I know there's a lot of people using Premiere Pro on here so I was hoping maybe someone might have an answer to this question.  I'm using Premiere Pro 2021 and I have a 5.4K clip shot with the Air 2S on a 5.4K timeline however when I attempt to use the YouTube export presets it only goes up to 4K.  I know I've seen 6K & 8K clips on YouTube so I'm wondering why my presets for YouTube max out at 4K.  Is there somewhere to find "YouTube preset" plugins or something along those lines?  Or if you want to export at 5.4K for YouTube do you just use the "Match Source - Hight Bitrate" option and upload the file to YouTube letting their encoder figure it out?  Thanks in advance for any advice.
