Improve HDR Export Workfow for YouTube

Currently, it's near-impossible to get YouTube to understand and interpret an HDR video properly when exporting from Premiere/AME. I end up doing my final color and master export in Davinci, then upload to YouTube. It just works, every time. With Premiere, you have to tweak every setting, make sure everything is absolutely perfect, and use the "Include HDR10 Metadata" checkbox in AME, which disables the CUDA renderer and falls back to CPU. Most of my projects are 1-3 hours in length, so even on a 9950x3D, that can be over 24 hours on a complex project that would otherwise take a couple of hours on the 4090. 

Even with using the "Matroska Colour Metadata Ingestion Utility" to embed proper metadata, YouTube usually still won't accept the upload as HDR.
