Premiere 2019 timeline lag on iMac Pro 27"

Since the Premiere Pro CC 2019 update (version 13.0 (build 225)), timeline updates are much slower.

Scrubbing the timeline sticks and jumps. Doesn't matter if footage has no adjustment/ effects applied or not. Although, adding effects (lumetri color) makes the lag worse.

Adjusting scale and position on clips in timeline from effects panel takes 3 - 5 seconds to update new parameters. Before update, adjustments were in real-time.  Very frustrating when adjusting 4k in a 1080 timeline.

All premiere projects are being effected by the lag after the update.

Please advise.

iMac Pro (2017) 27"

OS: High Sierra v10.13.6

CPU: 3GHz Intel Xeon W

RAM: 128 GB 2666 MHz DDR4

Startup: Mac HD

Graphics: Radeon Pro Vega 64 16368 MB

External media drive: G-RAID Thunderbolt 3

Dual Monitor: LG UltraFine Display 27"

Media file type: mxf

Color Space: C-log

Video Info: 3840 x 2160 (1.0)

FPS: 29.976

Footage Source: Canon XC15

We had the same issue and found the problem and solution.

Premiere Pro 2019 is not compatible with High Sierra. We tried installing Mojave and Premiere Pro 2019 on one of our Macs. Worked like a charm. No performance issues. But when we installed Premiere Pro 2019 on Mac with High Sierra, we got the same issues as you've all described here. However when we rolled back to the 2018 version, whilst on High Sierra, no issues.

Solution? Mojave + Premiere Pro 2019 OR High Sierra + Premiere Pro 2018. Don't mix them.

We've been trying to get Premiere 2019 to work across two separate machines and it's a no-go right across the board.  Our first machine is the latest 5K 27" iMac with 40GB of RAM installed.  Playing back simple footage with no effects is impossible even at 1/4 quality.  Yes, PLAYBACK.  We're talking 1-2 FPS in total.

Our second machine is a high-end PC build with a 1950X Threadripper, 64GB of RAM clocked at 3000MHz, a GTX 1080ti card and running on Samsung Pro M.2 drives.  Same issue, to a T. 

It's worth noting that we've been forced to roll back to Premiere 2017, which clears up all these issues across the board, and we're able to play back normal video at FULL quality with absolutely no hiccups or FPS drops whatsoever.  This problem has persisted with 2019 since October, and it's really frustrating that there's no fix for this after 4 months.  We even had an Adobe technician log in remotely to our machine and go through every single possible troubleshooting attempt with us.  He was baffled and was forced to turn it over to Adobe developers.  Never heard anything back, and that was 2 months ago.

I'm also noticing I'm having some performance issues as well. imac pro, 14 core 2.5 ghz, 128gb ram, vega 64.

I'll be scrubbing through my 4k timeline and will go over a clip that may have 2 other 4k clips stacked underneath it. It'll start the spinning wheel and completely lock up for about 20 seconds, then once it stops the hiccup it runs fine. This happens when I try and adjust the clip length (not even lumetri applied yet) and it locks. I can playback the timeline without render in real time but something this small locks up for 20 seconds?

Even my 2016 MacBook pro doesn't have this lockup issue.

Having same issue.  Before upgrading to 2019 - playhead was smooth as butter - no jumpy and laggy on any kind of footage in timeline.

I mentioned this on the original thread but in case anyone missed it, if you run a RAM preview in AE in the background, and on a loop, whilst rendering in Pr, your render will 'wake up' in Pr. Just having Ae open doesn't work, it has to be doing something in the background. A definite temporary fix until its sorted by Adobe.

Thanks, that’s good to know.

I currently can’t update to Mojave as I also use the iMac for music production and most of the plugins and host software is still not fully supported.

When I can update, it’s great to know that Premiere will run well.

Great to know, thanks so much! I have been waiting to update to Mojave per the usual precautions on all major OS updates but that's all the green light I need. Happy Thanksgiving all -

Have you tried changing the Video Rendering and Playback 'renderer' in Project Settings?

My playback was the same (much worse than Premiere 2018) until I switched to '...GPU Acceleration (Metal)'

(it was previously on '...Software Only')

    JP General,

    Sorry for the frustration. Have you tried creating proxies or transcoding your camera originals? If so:

    If none of these things work, try contacting us here: Contact Customer Care

    Thanks,

    ✭ ✭ Exact same problem here: latest Premiere cc 2019 version 13.01

    running on 2017 iMac OS High Sierra 10.13.5, 40gb RAM, Radeon Pro 580 w/8GB ram

    Adobe rep - please answer this post and throw us a bone, I cannot work with a client next to me it is so laggy: literally 5-10 seconds going from a rolling trim or razor or any other edit back to playing the timeline; plus it just takes a long long while for the new timeline to load up ( I see it but the monitor remains blank, audio silent ).

    Thanks-

      ✭ One more thing, don't know if this will be a useful clue or not to sorting out the problem but:

      I noticed right away when going to cc 2019 that saving a project took much longer than ever before, and this on a new  small project so size not the issue. And while I do use auto-save I am also in the habit of manually saving when I remember. The save status bar zips to almost 75% then takes an additional 5-8 seconds. My last project was with the last 2018 cc of Premiere, running mammoth 4 k files... no problems, timeline zippy ( with and without proxies ) and saving nearly instantaneous.

        very interesting...

        as many may have noticed ... I really consider myself as a critic of all new versions of premierepro since 12.1.

        But funny , in this particular case , I made the opposite experience.

        Since 13.0 the responsivness of the timeline , the time when I press play until it starts (until the playbackcache is loaded) , and the smoothness of playback, has definitely improved (at least for me).

        Before , in 12.1 it is abolutely unusable and jerky.

        In 13.0 and 13.0.1 it looks like back in 12.0 and earlier.

        But all of the other showstopping problems remained annoyingly the same (despite some hopefull announcements by oficials).

        What I mentioned during the last weeks reading many posts in this forum, it seems that people with os 10.13.4 and higher experience more performanceproblems than those with OSX 10.13.3 and lower. (maybe only to my cognition)

        my specs are quite the same as the ones above:

        IMacPro 8core

        32 GB

        RadeonProVega56

        OSX 10.13.3 !!!!

        current material from SONY A7S2 / 29,97 fps

        accessed either from internal SSD or external USB3.0 mini RAID (2xSSD in ICY-Boy-enclosure)

          Same here. Is this a bug that needs to be fixed or is a setting that can be changed?
