EXTREMELY SLOW EXPORT/RENDER TIMES DUE TO LOW CPU USAGE AFTER 2020 UPDATE.

It's 100% Adobe's failure to utilize ALL cores.  If you're using plug-ins, you're almost guaranteed single core performance.  GPU?, pft, it never and i mean never goes over 50% on my current 1070.

It's the terrible engine Adobe uses according to one of their own engineers.  Nothing will change until they spend the time and money to modernize.  I don't even care about compatibility any more, it's rarely dependable anyway from projects from the past that aren't even that old. 

No hardware you upgrade to will change this much at the average users level.  I've been with Adobe for 2 decades and had it on a half dozen top of the line machines (current 5950x, Gen 4 SSDs, 64GB DDR 3600) and it's barely faster than my five year old intel six core, why? becuase it's only using ONE core, which makes it roughly 1gz faster and it checks out.  There are times when I see it utilize all cores, but it's rare and of course there is no information that's easily found on it or explained.

I shoot with a GH5 heavily, 4k 60 8 bit mostly, and it requires "RENDER IN/OUT' constantly just to preview raw footage.  EVERY and and i mean every other software can play 4 of these at a time no problem, but Adobe can't even preview it without taking all that extra time.  Add your edits and effects and it doesn't really slow down that much at all showing it's the engine, but plugins definitely guarantee single core for me and I have all the Red Giant, Boris, etc that many of us use) so my life is spent waiting more than working every single project.

It's the engine.  An engineer finally admitted no amount of hardware will fix that, it may run a little better, but not efficiently and the evidence is right in front of your face every time you use it.  Adobe is making a fortune on the new subscription model and competition is gaining, but it's still not there and they know it. 

All the great new features are exciting to use and yet take things like rotoscoping that isn't optimized and actually crashes  half way through consistently making it useless (large project admittedly). 

The customer service and support is this "us" and paid by the post "contributors" that always offer "check your blinker fluid" level advice or just the old dependable "it must be your system" I wish I could block them as they just frustrate people more than help at anything above novice levels.

The fact that these forums are packed with ignored issues is all the evidence we need that they couldn't care less about fixing important problems and are focused on introducing more features to lure in new customers. 

The day I can completely migrate is a happy day...but I'm really rooting for Adobe to miracuously fix all this as I really do like the way all this COULD work in theory together.  but for now, as any pro house, they NEVER use dynamic link etc. because of of all the issues so why would you?  

Rant over.  Sorry I'm writing this as I'm waiting for a simple project to render with my fingers crossed I won't get an error.

I had the same problem after updating Premiere, but here's what worked for me: before you export the video, scroll down until you see "Encoding Settings" Change the option from "Hardware Encoding" to "Software Encoding". Also, checkmark "Use Preview". Hope that helps.

This is now Premiere Pro has always been for me and it seems to be very common for most, or at least, many. I'm on a Windows 10 PC with a 3900x and RX 5700 and 32 gigs of ram. Although, the new hardware encoding does seem to work pretty well and it uses ~50% GPU usage. It takes rendering from about 5-10 minutes to 1-2 minutes for the kind of small 3-minute projects I do. I find that every other version is broken for me. Every since 2020, without fail, every other update breaks hardware encoding, or something else. 

I've tested using all SSD with my media on a NVME drive and it makes no difference whether I use a mechanical drive, SSD, or NVME.

Hello,

it seems that I have the exact same problem.

I'm using the latest version of Adobe Premiere Pro CC on macOS. I have an i7 7700 with 16GB RAM and an AMD RX570. When I start the rendering process (FHD h264, RAW footage from a Canon 90D), the CPU is for about 10-15 seconds maxed out at 100%. However, after the 15 seconds, the CPU suage stays constant at about 25%. My GPU (RX570) usage is between 0 - 50% and the iGPU (HD630) is used between 0 - 40%. I've tried the export in both, Premiere Pro and Media Encoder and got the exact same result.

When encoding my screen records with Handbrake my system is always maxed out (not sure if this information is helpful).

Would be nice to get a feedback or tutorial how to fix that issue. 

Thanks,

Tim
