iMac 5K 27-inch, 2019

macOS: from Big Sur to Ventura 13.1

CPU: Interl Core i5 6-Core 3.7GHz

DGPU: Radeon Pro 580x 8GB / eGPU : RX 6600 XT

Memory: 64G 2667 DDR4

Premiere Pro 2023

editing 4k video's proxys (Gopro Cineform 2k)

 

Issue:

Every time when I use PP for a while( like 30-45mins) it will get laggy what ever play back or drag clips in the timeline, the funny is if I switching workspace it will happy to work more 30mins, in some case need to restart PP.

 

I thought it might be my mac is too old, so I upgrade a eGPU and update OS from Big Sur to Ventura. And the issue still there. I found PP is barly use my GPU both playback and rendering.

 

I've searched a lot either here or other website, didn't find any solution yet, I just wondring is there have any way I can report this to Adobe engineer because lots of people have the same issue since PP2019, and no any improvement to today. Not because I'm in the middle of the editing I'll change to Davinci immediately, it let me so frustrated.

Disconnect the eGPU.   (It's better used with a base model 21.5-inch iMac.)

Trancode your 4K source to ProRes 422 LT.  Edit in Sequences with Video Previews set to ProRes 422 LT with Playback Resolution set to 1/2.  Export to ProRes 422 LT.  Then transcode to other formats if needed.

Make sure your storage media can maintain the sustained data transfer rate of ProRes 422 LT.  Use Blackmagic Disk Speed Test (free from Mac App Store) to confirm this.

I spent half day transcoded proxies file from Cineform to ProRes LT than relink them and it works. PP can work fluently more than 2 hours now somehow it still needs restart after that. eGPU is still low porformance after all.

    Thanks Warren, you help me a lot.

    In my situration, if use ProRes I have 7TB original footages need to be re-transcoded, It's quit a pain to me. And I'm not sure if it works for me, I'll try ProRes next time.

    BTW do you think if just transcode proxys file from Cineform to ProRes then use the same file name can cheating PP to relink them?
