Hey Nath,
As the incompetent engineer who looked at your footage and couldn't reproduce the problem I thought I would jump in here and see if we can't sort this out directly. Before we do that though I'm gonna ask you to take a deep breath and understand we are trying to help here. Kevin is doing what he can to relay information back to us because he is our front line here in the forums. He is asking for information I asked him to acquire because I could not reproduce the issue on my system. No one is being difficult, incompetent, or any other disparaging remark you may care to throw our way. I'm confident we can sort through the issue but you have to be willing to provide the information we need. So, with that out of the way let's try to sort this out:
What I'm hearing from yourself and others is that you play a source file (eg the files you have provided - thank for that as it is always much easier to have these conversations when we are working from the same sources) in the Source Monitor you can play it all day long at Full resolution with no stuttering. However, when you then create a new sequence from that same source file then play it back you are seeing a stutter in the Program Monitor. This is reflected in your video demonstrating the issue (again, thank you as those are always helpful). I also understand that the issue is occurring on the same system with no hardware changes so the only real change of note is the version of Premiere. I don't disagree with that assessment, but I need more information to determine WHY that might be the case. You see there are a lot of factors that go in to the playback of media (side note: playback in the Source Monitor is NOT always using the same code path as playback in the Program Monitor so we can't operate under the assumption that performance is going to be the same). So the reason Kevin is asking about where the media is being played back from is important so we can rule out that there was some change that affected playback from specific hardware (it's happened before so it's not just something I'm pulling out of thin air). The other complication is that neither Kevin nor myself have been able to reproduce your issue with your media and your project. That suggests to me that there may well be another component in the matrix that we are yet unaware of and sniffing that out will help us understand how we might be able to fix the issue. We're not trying to waste your time, we're trying to understand the issue better because we can't investigate it directly yet. On to the matter of your setup. You stated that you have a 2018 Mac Mini. I'll work on finding a coworker with that setup to try the issue as well in the hopes that will get us closer. What would be helpful to know is what hardware is the media stored on when you're trying to play it back. You noted that you are using SSDs. Can you please clarify if those SSDs are the ones inside the Mac Mini or on an external drive. If they are external please note how it is connected to the system. External drives connected via TB3 and via network cable can each have their own set of troubleshooting steps. If the media is on an external drive I would encourage you, as a test, to move the media to an internal drive and try playback again. Does that make things better or worse? Now, here is the other troubleshooting step I would like to try: Please disconnect the eGPU and try playing the media back? An eGPU adds an extra layer of troubleshooting so I'd also like to understand how things perform without it. Please post your results and we'll go from there to determine the best next steps. Thank you for your time and patience as we try to resolve the issue. For anyone else that is following along please feel free to add your results as well. As not everyone is experiencing the issue it can be helpful to see how different systems compare when running the same test. Tom
