Question

Premiere Project and Sequence really Lags

I have been working on a feature length doc in Premiere, and recently had to transfer the whole project from a 4TB drive to a 5TB drive (both USB C Lacie drives). Since then, I have experienced really slow performance from premiere when working on this project, in terms of effects control panels is laggy, 1-2 second lag between hitting play and playback starting, save takes 2-3 times longer than it used to, video preview doesn't follow when scrubbing, video thumbnails take ages to load in timeline.

Premiere and my computer don't lag when I open other smaller projects, and even lags much less when I am working in a sequence with much less going on (like a trailer sequence for example). I have cleared cache files, turned off growing files refresh, ran first aid on my hard drive, removed un-needed media from my project file, reinstalled premiere, restarted my computer, duplicated the project, renamed it and opened the new project file, nothing has worked.

Video playback isn't the problem here, I don't have a ton of dropped frames, once playback starts.

Specs
2018 MBP

32GB RAM

2.9 ghz quad core i9 processor

Pro Vega 20 4GB graphics card

Premiere Pro CC 2019, fully up to date

Footage:

Mostly Cinema 4K, C-Log profile Mkv files from Canon c300mkii

Proxies: Custom-wide Quicktime 720p proxies

A good amount of archival footage of various sizes all .mov or .mp4

Trying to figure out how to clean it up and make it smoother, or if I just have to deal with the unbelievable size of the project as an impediment to expediency.

Thanks for your advice in advance

AskKrause,

Sorry for this. How does one of your backups behave? Let us know.

Thanks,
Kevin

Backup project/drive acts similarly/even slower. I also had to transfer that to a larger hard-drive at the same time. That's really when things slowed down drastically on both the primary and back-up.

Hi,

What do you mean by that? All the project files are updated to Premiere 2019, the backups are duplicates of the primaries on a separate drive. All the projects are up to date in terms of the cutting/editing itself.

What I mean is: were your project files updated from 13.0.x to 13.1.x at any point along the lifespan of your project? Updating project files, especially large ones like features and docs can cause corruption in the updated versions.

Another concern I have is the new drive. Was it initialized using the same protocol as the original Lacie drive? Are you certain you are using USB 3.0 and not USB 2.0 connections? Have you done a speed test?

Thanks,

Kevin


The drives were initialized the same way, I'm sure its USB 3.0, the speed test showed normal read and write speeds for USB 3.0. What's really weird is that my big sequence with the whole film in it moves about 25 times slower than my trailer sequence with only about 1:30 of media on it, which leads me to believe its something in the sequence or the mix of media in that sequence.
