    MC 2021.9 vs 2018.10 Prores 4444 performance drop

    Hello,

    We have Mac Pro 2013 trashcans with 12 core CPUs (MC 2021.9, 32GB RAM, Mac OS 10.14.6). I have some UHD Prores 4444 video clips I had hoped to edit with natively via AMA, but Media Composer 2021.9 cannot handle them. It pins the CPU according to Activity Monitor and it drops frames during playback, even with the video quality toggle set to Best Performance. I will say that Quicktime Player X / 7 and Premiere 2021 have no issues playing / editing the same clips on that workstation. I also just tried the same clips on a Mac Pro 2012 silver tower with Mac OS 10.13.6 and lo and behold they play just fine in Media Composer 2018.10. Perhaps the QT engine in MC 2021 needs some tuning? It's not a storage bandwidth issue, the storage I was using on each machine was 3-4x faster than the clips' data rate.

    The 2021 versions of media composer don't use the quicktime engine, they use the new universal media engine (UME) introduced in 2020.4 to link media. On windows I know you can choose between linking with AMA or UME, I don't think that's the case on mac. 

    Are there any framerate adapters, colour adapters, or frameflex adapters on the footage you're trying to play back?

    We are not applying anything at all. Just trying to play the clips as is.

    You could try to reset your Media Composer User Settings, and delete the MC state file, but that normally solves interface issues, not playback issues. 

    You could try to create a support case and a representative there could report this as a bug to engineering if the issue can be re-created.

    Thanks Philip. I did open a support case with Avid #04268968. They suggested that I force MC to link with Quicktime instead of UME. That did solve my problem in this case. i noticed that CPU usage was much higher with Quicktime than with UME, but it played smoothly. Unfortunately, this workaround will not be available if I upgrade the OS beyond Mojave because Quicktime would not be available in Mac OS 10.15+. I'm sure there's some kind of tuning / optimization Avid could do to improve UME performance. Fingers crossed they'll fix this in a future release.

    Yeah, that's what I was saying earlier. Using the QuickTime engine is a good work around for me, but isn't a good long term solution as it's discontinued and legacy code now. Sorry to hear that! I would strongly suggest you stay on your OS until you're sure that UME is good enough for you and works in your Workflow in the future. Don't rush to update OS if you can.
