Premiere Pro CC running Painfully Slow on MAC

I'm using a 12-core Mac tower (3.46 GHZ + Radeon RX580) with 128 GB RAM . I have a 2TB SSD that I use for most of my project storage and write to a standard 7200 RPM drive. Here's the thing. On short exports—5-10 minutes runtime—everything is fine... But my longer form content (like my current 1 hour runtime export), it's taking FOREVER. My performance in editing is fine... it's the export that's killing me. I can render and export the EXACT SAME FILE on my Macbook Pro (32 GB of RAM, 1 TB SSD, 6-core 2.9Ghz with Radeon Pro Vega Card+Big Sur) in 8 minutes. On my box box, it estimates 12 HOURS?!?!? What is going on???

Just to tag on to this old feed, but I'm having the same issue on a brand new iMac. Sounds like a big part of my fix is just pulling media from an external drive instead?

I have had a similar problem recently on my Mac Pro. While this can certainly happen for other reasons, your description sounds like exactly what I saw. Playback stops, but everything else still works fine.

In my case, turning off CUDA acceleration solved the problem. I am currently using OpenCL acceleration instead because of this problem. I suspected a conflict with the current Geforce driver, which I don't think you are running on that model of MBP. However, it might be something else.

Clearing the condition, in any case, requires a reboot. Just changing the Hardware Acceleration setting is not enough.

I have seen that also on an HP pc tower, i was able to zoom the timeline but it never played.

i solved it with a "restart"

my guess back then was:

1- the unstable QuickTime on window!

2- clearing the media cash will force PP to rebuild a cleaner one.

Hi Brendan, I'm sorry to hear about this! Neil is right in that to help you out we'll need to know more about your situation. Could you tell us what kind of footage you are editing with? How full is your hard drive with the media? Are you using any other connected hardware for example for audio or video output?

Thanks,

Matt

That laptop may not have really adequate hardware to work well ... let's get a full listing of the gear, please ...

CPU/RAM/GPU/vRAM, video driver number, the number and type of drives connected to the computer, how they're connected, and the type of media you're working with what effects.

Sounds like you've only one drive, and especially if it's an old spinning disc, that would be a big hangup right there.

Neil
