HELP: Premiere Pro CC not using all CPU and RAM during rendering and export

Having the same issue, rendering out footage from my GoPro Max (360 video) it's using 50%-60% CPU and about 8GB of RAM and 30MS/s of disc.

I have a Ryzen 5 3600 so that's 6 cores (12 Threads) able to turbo boost and stay at 4GHz throughout the render due to the watercooling, 64GB of RAM (2x32GB sticks) with only 16GB in use overall (so plenty of spare to go at) and a nVidia 2070 with 8GB of its own RAm, this is sat at about 26% usage (Premiere only allowed software encoding, not hardware encoding, said my system doesn't support it, which is strange as everything else likes cuda acceleration, Sony Vegas knocks renders out in seconds through it, but that also utilises the CPU fully with hardware acceleration off). The disc is nVME gen4 so capable of 3GB/s so the 30MB/s is no sweat for it and showin 1% activity.

Seems odd to have an estimate 2hr render when the software's not using the entire system, and a bit annoying as one thing I built this rig for was video encoding, guess I'll have to use Sony Vegas for it instead.

It might just be down to video codecs, I don't have a particular powerful laptop (i7-6600U, 12GB ddr4 ram, Radeon R7 m360 which stay on power saving mode or else Ill get it overheating and shutdown) 

My experience: I have edited footage in Full HD 422 from a Sony x160 broadcast camera (i think they record at 50mbps or something). Export times were incredible (like 5mins for a 3min highlights video with colour grading and everything, very good for my underpowered laptop) 

BUT when I use my Sony A7iii 4k files (at 60mbps or 100mbps) I see render times massively extended (yes i know its in 4k and a higher bit rate) but I'm talking 10 - 20 times longer export times and it is the same even when working with footage from dslrs or something. I really think it all comes down to codecs which is really disappointing, maybe a beast pc would help. But looking through this thread there is definitely a bigger problem on hand with PP

year 2018 and still same issues and still no answer from Adobe. Thanks!

Commenting to see if we ever find an answer to this.

I'm exporting a 3 minute 4K video with no effects or even color applied but my CPU is hover around 66% load and Premiere is only utilizing 7.2gb RAM out of 22 allocated to it. It's says its going to take it 1.5hrs to export which is absurd.

System:

iMac 27" Retina 5K

4Ghz i7

24gb DDR3 Ram

AMD Radeon R9 M395 2G

If it's true that Premiere is designed to not utilize all of the power available to it this is a huge issue Adobe needs to correct or at least provide the setting options to change.

We got a monster 56 (dual, 14 core xeons) thread dual cpu computer in the office a few months ago. When rendering from premiere it's only using about 12 threads (6 cores) and only using a small percentage of thread usage on each. This running off a samsung 960 pro (nvme) and GeForce 1080, neither of which were sweating. Mixed format timeline was still jumpy a bit too unless it was cineform codec.

Hello all,

I was having this same issue and I believe I found the problem, at least in my case: The denoiser effect.

I had a fully finished ~20min sequence - including multiple Ae video layers, audio round-trips from Au, etc - and, just to render or export, it was taking my PC to 2+ hours. With the Task Manager open, I could see Premiere Pro CC 2015 only using about 30% of the CPU and about 40% RAM.

I copied the entire sequence into a new identical sequence, cut off all the denoiser effects (I use NeatVideo denoiser, not RedGiant) and started the render/export again. This time, Task Manager shot to full 100% CPU and 70-80% RAM. Estimated time to render... 30min!

The only thing I changed between the two sequences was cutting off the NeatVideo Denoiser effect.

I say I found the "problem" not the "solution" because, well - I need to render/export it out with denoiser ON so I can see my final product haha.

I hope this little bit of information helps point us to the solution. Maybe it's a question for NeatVideo or RedGriant?

My Rig:
Windows 10
Intel i7-5820k (overclocked to 4.0ghz)

32gb RAM

EVGA GeForce GTX 970 4GB

All SSDs

Adobe CC 2015

Adobe software was always buggy - crashes and other problems are a pain that I'm facing for years and I guess they just don't care.

I guess I have a powerful machine - Alienware with i7-4900MQ, SSD, two GTX 780M cards and 32GB of RAM and I got like 15% of CPU used while rendering and just one NVidia card being used while rendering.

I've managed to improve my rendering speed - it's far from perfect though - I get 50% of my CPU now and SLI seems to be working but I'm not 100% sure - I get like 30-40% of performance on one 780M and 17% on the other. Really weird. Seems the Media Encoder is using just like 1/6 of the full performance of my setup (or even less), but it's still better than using just 15% of my CPU.

Here's what I did:

- I cleaned the cache settings in Premiere Pro CC (Edit > Preferences > Media > Media Cache Database)

- I deleted all Temp files from my computer (I'm using Windows, so you need to delete the stuff in the AppData/Local folder)

- I started Media Encoder first and then Premiere Pro.

Now i get 4x faster render times even though my machine should be able to get much better render times than this - there's still a lot of room for improvement. I don't get why it's using just 50% of my CPU, 30-40% of one GPU and just 17% of the second GPU.

Just as much as I don't get why I cannot change the language of the software within the software - Adobe are masters of intuitivity and they're always listening to their customers. Yeah, right...

A little bit disappointed that any adobe staff come for help here and answer us..

I have also problem same all of us with rendering time and cpu 20% use with 10 hours rendering for 3' timeline FHD with effects.

I have a powerfull config as well with 2 SSD for current editing, scratch disk, cache ...

I7 5820K 3.3ghz 32GB RAM GTX 970 win 7 64bits

So we can optimize ours config and used 100% cpu and not 20% as before CC ??  or we have to switch to davinci resolve ??

I just upgraded from a 7 year old QX9650 with 8GB RAM and a Geforce GTX680, to a dual Xeon E5-2630 with 128GB RAM and a Titan X 12GB GPU.

My old system would play UHD Prores video at about 70% CPU utilization, no dropped frames. But the new system drops 40% of the frames playing the same clip in the same version of Premiere (CS6) and CPU utilization is a paltry 3% in Taskman!

Isn't there any way to get Premiere to utilize the resources better?
