Playhead will lag and jump after a few seconds in Premiere Pro 2019

CC18/19 Playhead lag when scrubbing full screen TL in Mojave

Inspiring

Mo,

I have screen captures on my post:

Here is the bottleneck:

Processor: 2.2 GHz Intel Core i7

16GB RAM

Graphics: Intel Iris Pro 1536mb

CC2019 is very particular on hardware and your GPU and CPU are far from ideal to ensure smooth and seamless playback.

Try this:

Drop playback resolution to 1/2. Disable High Quality Playback and let me know what happens

Thank you for your input, but I have already tried this method to no avail.

Radeon Pro Vega 64 16GB

And same as Jonathan, I have tried all of this.

Hi, I just found a solution (for me) on another forum post here:

If any of you also have Insta360 software on your computer - this may be the cause of your problems.

I uninstalled the software, my program is working perfectly again.

Pity I have spent an entire 9 hours trying to fix this - I've lost all my settings, everything.

Adobe if you read this - you need to work with Insta360 to make sure their software doesn't sabotage yours.

Hope this helps you all - if not, best of luck on your search for a solution.

Hmm, I do have Insta360...

I will have to try when I get home and see if this is the fix. If so, you will have saved so much time and energy you should be knighted by the Queen.

Thanks for the replies everyone.

The only thing that worked for me was uninstalling my current version of Premiere and reinstalling 2017... And even that acts up from time to time, but I think that was linked to having Bluetooth headphones connected, believe it or not.

I believe uninstalling your OS would probably fix it, though that is a lot to have to go through for this issue that Adobe should have solved ages ago. Either way, this is a ridiculous thing to have to deal with. Especially with tight deadlines.

Same here, disconecting the Bluetooth connection solved the problem...

I am having the exact same issue that everyone has mentioned here. Has anyone found a solution?

I have been talking to Support and have went through literally every step by step re install, creative cloud clean, cache wipe, preference delete (thanks for that by the way.. keyboard shortcuts gone, and nothing fixed..).

I've even tried new project, and copying only the latest timeline from the old problematic project, and it's as if it carries over the sluggishness. There is nothing on that timeline that is out of the ordinary to any other Project so why is it doing this.

It's dire, it's impossible to work on.

I seem to have possibly solved the issue on a test machine by doing a complete erase and install of the operating system. I will be doing the same on my main editing station later this week and will let you know the results.

Inspiring

Full Mojave erase and install with a fresh CC install of just Premiere does not resolve the issue for me.

Adobe, this has been an ongoing issue since CC2018. We make a living using this software, please stop ignoring this.

I have been experiencing horrible playhead lag in CC18 and CC19. I believe that I have narrowed it down to being an issue with Mojave.

I have the same thing happening to me however Im on a MacMini 2012 fully loaded. By any chance is your video rendering and playback set to Mercury Playback Engine Software Only ... and greyed out?

No I can select between Mercury Playback GPU Acceleration (metal) or Mercury Playback GPU Acceleration (Open CL).

I took the project I wrote this post about and opened it up on my 2014 MBP and everything works as it should. I was able to finish a rough draft of the edit and get it out for review. I have another project that I am working on that was started on this MBP late last year. I opened it up again this week to do some more work on it and it is working fine on the MBP but when I move it to thew mac mini and open up I get beach ball of death every time I move the mouse.

This is TOTAL BULLSHIT. I have lost so much time to this Issue. I've tried every trick, clean instal, delete preferences, different render engines, reseting workspaces, moving scratch and media cache to their own separate ssd, updated premiere, updated Mac OS, bought an egpu, bought ssd's. There is some glitch in premiere that if I open a project on this laptop and then move it to the mac mini it's too glitchy to work on. IS there some preference or setting that gets set that allows it to work on the old hardware and not the new? perhaps something with the multicore processes in the Mac mini or something similar. Not sure but I guess Ill just work on the MBP for now and keep new projects to the new computer only.

Thanks for replying and it seems to be the same for me. Opening the projects on my PC at work everything seemed fine. All my projects used to be just fine on my Mac, but now all of a sudden do not. It's almost if Apple's update is killing the system. Probably because they want everyone to use Final Cut Pro10 and make all of the other systems run like shit on upgraded software.

Whenever Pr acts like it doesn't normally, refreshing the prefs fixes it most of the time. Start Pr with the opt/alt key held down.
