The amazing Joe Marler reports on our Discord:
The v11.1.1 fix involving "MXF media to plays back incorrectly" (only XAVC-L) had been filed as issue 449 in the FCP Cafe bug database
There was also an unannounced fix in Pro Video Formats v2.4.1 the day after the Final Cut Pro v11.1.1 release.
That Pro Video Formats v2.4.1 fix addressed sluggish Quicktime XAVC-L playback on Apple Silicon.
I tested the Final Cut Pro v11.1.1 fix on bug #449 before installing Pro Video Formats v2.4.1, and it none-the-less fixed the specific XAVC-L bug involving black frames when using the Final Cut Pro Import dialog on Apple Silicon.
However the QTP bug was suspicious. It might have been in/Library/Video/Professional Video Workflow\Plug-Ins/AppleAVCLGCodec.bundleor in/Library/Video/Professional Video Workflow Plug-Ins/AppleMXFImport.bundle, but I did binary diffs on those and diffs of the decompiled pseudocode and I don't see where it was.
The Final Cut Pro v11.1.1 fix was possibly in the Flexo private framework, maybe inMXF::FileReader.
This is what I absolutely LOVE about the Final Cut Pro community - we have such insanely smart people just openly sharing very technical information. Awesome.
Thanks Joe for all your on-going help, support and genius in both the wider post production community, and ESPECIALLY here at FCP Cafe in the GitHub Issues!
The Pro Video Formats v2.4.1 update was released on 23rd May 2025, so if you haven't already updated, please do via System Settings or downloading manually on the Apple website.
