Question

Delay when moving between program and source monitor

Hoping someone can help me out with a really weird problem I've been having. I am getting a lag/delay in my Source Monitor after I drop a clip into my timeline. 

 

Some background; I'm using an M2 Macbook Pro with plenty of power, and editing off SSD's. I have zero performance issues or any sort of skipped frames or other lagging when I'm playing back footage / editing. I can edit 6k full res with no issues. (I'm mostly editing RED footage). BUT, when I'm pulling selects and bouncing between the source monitor and timeline there is a delay for playback to start again / for me to be able to scrub through the clip in the source monitor. I drop the selection I made in the timeline, then I go back to the clip in the source monitor and its frozen for 3-5 seconds, can't scrub, can't hit play, etc. Then it starts to play and there's zero issues, I can scrub through, play, etc as much as I want with zero delays, until I drop another section of the clip into my timeline. Then the same issue repeats.

 

It feels like some sort of UI issue. It's like my source monitor is going to sleep every time I drop a clip into my sequence / play anything back in the program monitor, and then it has to 'wake up' every time I go back to it. 

 

I have 'put hard disks to sleep when possible' turned off on my mac and that hasn't seemed to help, and I don't think drives going to sleep is the issue because it happens EVERY TIME even if I'm only in the program monitor for just a second.

 

This happens when I'm editing soley on my mac as well as when I'm using dual monitors.

 

Any help would be greatly appreciated. Thanks

I too am experiencing this problem. I'm working on a fully-spec'd out M4 Max MacbookPro with 64GB of RAM and have the footage stored on a GLYPH SSD. This has been an issue across multiple projects, using different video sources including RED, DJI Drone, Canon R6, GoPro etc. Any time I'm making selects and dropping them into the sequence, the Program window lags a good 4-10 seconds every time. It sounds like a bug in the software. Someone please help!

Hi everyone!

Same problem here, but there is a twist...

Everything was fine in 24.6.4, then i uprgraded to 25.1... I started to experience this source monitor lag/delay...

I am editing on the base M4 Mac mini, I tried every option i came across the internet, no solution. So i downgraded to 24, and the problem was still there. ???!! 

 

Anybody have a solution for this? Seems like no matter what version i am using, the source monitor is cooked.

I am experiencing the same issue. Please would really love to know if there are any updates.

 

I was in Windows and Premiere Pro was working fine, but about a month ago I moved to a brand new Macbook Pro M4 Max with 128GB RAM, installed the latest PP version at the time PP 25.0 and this is when I noticed the same lagging/freezing of the Source Monitor after moving a clip from Source Monitor to the timeline. The Source Monitor freezes for about 10-15 seconds, everything else keeps working fine, I can scroll on my timeline and the Program Monitor shows my scrolling, but the Source Monitor remains freeezed for those 10-15 seconds. I know 10 seconds sounds like a very short time, but is not when you are editing and reviewing tons of footage. Today I updated to PP 25.1, but the issue is still there. Please help.

 

New computer, latest Premiere Pro recently installed with no personal settings, no cache saved on new computer, editing from local SSD drive, and footage was downloaded from online footage library so it is formated for NLE softwares.

I've been in touch with Apple support about this. They tested my Mac, the monitor activity, made me reinstall Sequioia, even went into safe mode, but the issue is still there. They pointed at something related to Adobe.

 

I have also followed the steps of the answers in this post with no luck. Has anoyone found a solution? Is there anyone form Adobe that can help here? Thanks!!

sorry for the late reply, did you try to reset premiere pro preferences?

are you editing on external drives or local drives?

did you try to clean your media cache and delete video previews from sequence?

try to set sequence settings => video previews to something like QuickTime ProRes

if you are on H.264.

Try to disable Mercury Transmit, check if it makes any difference.

Hi,

I appreciate it.

I did everything that was advised to do in your email. It did not work. I've
attached a video recording so you can see what it looks like on my end.

Thank you.


Best,

David
