MXF based sequence playback falters on mac M2 machines

[Sam2023Roffa]

Hi, as written on the discussion platform earlier, I have trouble with audio and some video playback with an MXF project. Audio falters heavily (no playback every other second), video does play but not smoothly. All possible measures have been taken, nothing works to fix this. Talked to some other editors who ran into the same problem recently, some with MXF from Sony, some from Canon. Their solution: move their project to DaVinci. I am in a long haul documentary series, moving to another editing platform is no option. I've been working with this MXF material for the last 4 months, only after the latest update did it start to go wrong. I'm running the latest version of Premiere Pro (23.6) on a newish (6 months) mac mini pro M2 chip with latest version OS (Ventura 13.5.1). For now I moved my project to an older iMac (intel) where it runs perfectly. It seems like a bug, please look into it.

Activating this conversation ass the newest PP update is giving the same bugs: faltering audio every few seconds, faltering video playback very often, files randomly going off sync. Seems version 25.0 is very buggy, same as about a year ago

There have been numerous issues with MXF from various cameras. Some things fixed in the current shipping, some supposedly handled in the public beta, some ... I have no clue.

@Fergus H @jamieclarke help?

Hi @Sam2023Roffa -  We need a few more details to try to help with the issue.  Please see, How do I write a bug report?

You say "For now I moved my project to an older iMac (intel) where it runs perfectly. " What is the differences between your M2 and the imac?  Do you have the same settings, same os?  

Please post a screenshot of your media file properties so that we can see exactly what you are working with.

Are there Plugins that you are using?

You mention working with MXF files do you have the sony catalyst or catalyst browse plugin installed?
