Hi all.

I could never play 4K files in V19 without having to transcode to something else via Shutterencoder so took the plunge to upgrade to V23 at the weekend, thinking the new version would resolve this.

Unfortunately not.

I'm shooting with a Canon R6 II, Clog3 enabled and switching between HD or 4K IBP files. Have no problems playing and editting HD clips but 4K ones still stutter. I've tried adjusting Dynamic Ram and File I/O on off without effect. The clips play absolutely fine in external progs like MPC-BE.

Interestingly the 4K files I've shot on my OnePlus 9 Pro mobile play without issue, so is this some weird Canon bug?
