Canon XF705 HEVC-MXF 4K files have very choppy unusable playback even at 1/8 resolution
Thank you for including HEVC-MXF support in your recent update. However at 4K the files are still unusable, even at 1/8 resolution I get choppy playback (works fine at 1080) which means I can't edit. I have a 2 day old iMac Pro with upgraded memory, processors, and video cards.
Canon XF-HEVC performance is now greatly improved in the May release of Premiere Pro 2021 (v15.2)

Premiere also won't let you create Proxies with the Canon HEVC-MXF files (something about the audio channels/format) but if you change the file extension to .MPG it does.
So seems to be a limitation with Adobes implementation with the HEVC-MXF format.

Import is ok but the files are unreviewable and lagging. There's no way to actually edit these files and I'm running:
