Question

Annoying Source Monitor lag/delay

Hello beautiful community friends. Had a question that I can't seem to solve for the freakin LIFE of me. 

 

I have a new 2022 Mac Studio M2 Max. I have freakin 96 GB of Ram. I'm not editing really high res footage or anything, just simple stuff from my Iphone 14Pro. I'm running the latest Mac iOS and version of Premiere. 

 

I'm experiencing a frustrating lag in my source monitor whenever I insert a clip into my timeline then come back to my source. It usually takes like 6-10 seconds to play. 

 

My source monitor is typically fine...no lag if I'm just scrolling through and playing footage. But if I insert a clip FROM that source monitor TO my timeline, it takes a while for my source to start playing again. It's almost like it's "loading" or something.

 

(Also note, I don't have any heavy graphics layers or anything complicated. Just regular boring iPhone clips. I've also done literally every YouTube fix (i.e. clearing Cache files, etc. I also have nothing else open). 

 

I feel like it must be some weird playback setting I have? I dunno....

 

(I'm including a few screenshots of my settings to make sure I'm not being a dingbat).

 

Love and appreciate anyone who can help me with this. I will buy you flowers honestly.

Having the same issue on a M4 max Mac Studio I just purchased a week ago. I tried everything and nothing seems to fix the issue. The weird part is that with all the same conditions, I do not have this issue when I open the project on my M3 pro Macbook. Is my Mac Studio bad? Should I return it while I still can? I'm not sure what to do, any additional help would be great. Thanks!

Hi David Dzurilla,

 

Sorry to hear about this. We can get this checked. Could you please confirm the version of Premiere Pro you are using and whether you are using a multi-monitor setup? If the project and media are on an external drive, have you tried moving them to the internal drive and checking if it's working better? Also,  let us know the device on which the media was captured & the format of the media.

 

Thanks,

Sumeet

Thanks so much for the visuals, that'll help us investigate it on our side of things! A few more suggestions we could try.

- Try a different workspace.

- Go to Window > Workspaces > Reset to Saved Layout

- In your Audio Hardware preferences, do you have any other options under Default Input? Try switching to "None" if it's there.

- What format is your external hard drive?

- Have you tried making the Source Monitor panel smaller?

- Is your Mac in a scaled resolution? Meaning is your overall UI (regardless of what app you're using) scaled through the MacOS settings?

 

Let us know, we'll look into it.

Hello @caroline_edits,

Thank you for your response! I tried all your suggestions and was not able to fix the issue. My Working drive is APFS and I use my MAC at the 2k resolution. However, I tried all the resolutions and still had the same issue. I still have no issues with the source panel when I am editing on a M3 Macbook Pro. There has to be some sort of compatability issue with the M4 Max chip. Let me know what you find! Thank you!

Hey @jeffk79185465!

I have the same problem on my M4 mac mini with Premiere Pro. Everything was fine in 24.6, then the problems started in Premiere 25. Thought downgrading, but the problem still persists... 

Did you solve this problem?

Looking forward for any tips or solutions!

Thanks!

Actually, phone media is normally long-GOP stuff and well ... that's often a lot harder to edit on a computer than say 8k RED media. Still, those rigs typically do pretty decently with this, so I'm hoping Warren or somenone has an idea for you.

 

Oh ... Preferences, Audio, make sure that 'default input' is set to "none".

Everyone's mileage always varies ...
