Bug: Timeline playback is extremely laggy in CC 2019

I'd classify the current timeline playback implementation as very buggy in the most recent release. I'm running with up to date Nvidia drivers (with the latest version of Cuda), and in testing a project on the previous version and this version, the playback lag rendered editing in CC 2019 completely unusable.

Is anyone else dealing with similar issues? I'm on a Windows PC laptop, i7-7700HQ, 32 Gigs of ram. The previous version worked perfectly for editing GH5 10-bit footage. As a test, I have the same project setup in Davinci Resolve 15, and it plays and perfectly with zero lag.

Adobe, please fix the playback and Cuda acceleration problems in the latest version!

I am not using proxies. I have used the proxy workflow before, but am not prepared to unnecessarily change my workflow due to a bug. I'm sticking to CC 2018 since the timeline playback works as it should.

I'll give CC 2019 another try in a few months once they've worked out the bugs and fixed their Cuda support.

This is especially true when working with Dynamic Link. CC 2018 worked fine for me, with or without proxies, and now rendering out even basic Dynamic Link comps takes much longer. I'm on a 2013 Mac Pro with 24 GB of RAM, and i"m working largely with still photos and a few blended layers on top. Nothing that I've had problems with before, and yet the new update has made it excruciating to render.

Hey guys,

I was also experiencing stuttering in Premiere Pro CC 2019.

I recently purchased the Atomos Ninja V, an external recorder that can record up to 4k60p 422 10-bit signal.

I tried everything to fix the lagg and even my proxy files were lagging.

I went into sequence settings > video previews:

There i saw that the video preview quality was set sky-high on a DNxHR RGB 444 UHD 25 / 3840x2160 format with the option

'compositie in linear color' turned on. This was clearly the problem.

I changed the video preview settings to DNxHD LB 1920x1080 with the option 'compositie in linear color' turned off.

Now my Premiere runs smooth like butter again.

Hopefully this helps for some people, cheers!

The linear color check, unfortunately, does not solve my problem. In CC 2018, I have the identical project set up as a test where linear color is checked and things run flawlessly. I've tried checking and unchecking in CC 2019 without success. Playback chugs along.

At this point, I'm waiting for the next update to see if they sort out the errors. This issue is present on both my 1060 and 1080 TI cards. So I'm pretty certain there's an issue with the Cuda implementation in 2019.

THIS! Fixed my problems. Was having purely miserable playback in CC2019 even after rendering, while CC2018 was playing other projects perfectly. Mine was also at 4K Animation Codec for some reason. HD DXNR fixed problem immediately.

Unfortunately gotta change it for each sequence one at a time in the project but still, seems to fix it.

This Solved it! I have system with duel processors @ 2.2 GHz with 44 Cores total and 128 GB of RAM. Shouldn't have issues right? I installed the new RTX 2080Ti. I ran into stuttering on my timeline every 5 seconds as soon as I upgraded to Pr 2019. I tried Proxies, footage conversion, yelling, and nothing fixed it. My computer at work, which is similar, a little more powerful, but has a Quadro P6000, has no issues. I was baffled till I tried switching my timeline settings finally as suggested here and it fixed the stuttering.

- I selected my timeline sequence.

- Right clicked and chose sequence settings

- Changed my Editing Mode to DNX 1080P

- Previews to DNX HQ 1080p 24

- Codec DNxHD

My guess is the new NVIDIA RTX 2080Ti is just less stable than a Quadro P6000. Your Codec might differ based on your card, like at work my P6000 ran Pr 2019 fine with no stuttering, but play around here till you find what works.

Just checking in to say THIS SOLVED MY PROBLEM! I was editing smoothly the other day and then suddenly opened up old time line and suddenly lags when cruising through timeline. I was frustrated for a few hours and eventually found this fix! Thanks so much

I had the same problem when updating to 2019.

Turns out the supplied external drive (USB 3.0) I had my clips on was formatted 'ExFat'. Since moving them to a Max OS Extended drive things ran like usual again.

I also changed the exFAT to HFS + and solved the problem.
Thank you very much!

Experiencing exactly the same problem. Been using Premiere Pro CC 2019 since it was launched and it was working perfectly but now the timeline is running really laggy and choppy.

I'm using my normal 4k footage and Cineform 720p proxies workflow and it's never been like this. It's almost unusable!

I've opened the same project in Premiere Pro CC 2018 and I have no play back issues at all.

There definitely seems to be a problem with the current version of Premiere Pro CC 2019.
