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

Hello,

I am using Premiere Pro CC on a Windows 7. My timeline is quite simple with two videos, one with the movie (mpeg) and the other with the subtitles (avi).

When I render the sequence in PP or export, the rendering time is way too slow and it only uses around 15-20% of the CPU and 3 GB of RAM.

My hardware config is :

- CPU : i7-4770k 3.50Ghz

- RAM : 8 GB

- Disk : 2 x 3 TB SATA (no raid)

RAM is not the bottleneck, neither the disk access.

I have tried rendering and exporting the same project on an iMac (with an i5 2.7 Ghz and 4 GB RAM and only 1 disk) and the result is 4x faster !!!

The CPU usage is close to 100% as well as RAM usage.

So how come PP uses all resources availble on an iMac and not on a Windows 7 ?

Is there any known bug or software bottleneck on Windows 7 ?

My machine is brand new and nothing much installed besides Adobe products.

Any help is very much appreciated.

Thanks,

Hello, i have been having the same problem on my hp zbook 17 g2, i got 16gigs of ram and 4gigs of quadro, but all was slowing down and cpu was just at 20percent. Here is the solution that has worked for me after long days of trying. I had changed soe setting in the bios, i went back and put everything to default, then came to the nvidia control panel put the global 3d settings to base profile, changed my power plan from high  performance to hp optimized, opened premiere and cleaned cache, now everything is back to speed, 100percent usage on all and render time is just seconds.

I have noticed that when my CPU power setting is on 99% instead of 100% I get almost twice as fast render times from either direct export or AME export. Set both minimum and maximum power states to 99%.

I'm experiencing a similar problem with Premiere Pro when it comes to rendering. Playback is fine but when it comes to rendering only 15-20% of the CPU is being used. I checked the GPU load and i noticed that it is maxed out to 99%. I find that weird so what i did was I turned off the mercury playback engine. BOOM. It fixed the issue. I did a render and it started using 99% of the CPU. Render time improved by 40%-50%. I don't understand this because Mercury Playback is supposed to speed things up. REALLY WEIRD.

What video card are you using? I've only ever seen my GPU jump to around 70% when working it hard on purpose to test. Otherwise it jumps between 0% and 25% as it works through the sequence.

GTX 750ti. This problem does not always occur. Just in some projects and I don't understand why as I always use the same set of color correction tools. I wonder if you could try turning off your Mercury playback engine and see if it fixes your problem too(although we have slightly different issues).

I am having the exact same problem... rendering and exporting is only taking 20-40% of my CPU and its horribly slow.  There is no load on the disks (I have 3 different SSDs).  There is def a bug going on here.

I got nearly same issue.

I was using i5 3570 when I m rendering and CPU usage was %90-100. I upgrade my CPU to i7 3770 and usage decrease %30-60 (Premiere CC)

I found it in the internet. I tried this but doesn't work for me. Maybe it could be usefull for you.:

Premiere Pro not using 100% CPU when encoding? on Vimeo

Same here! Have a very fast PC but very slow render times...

This is a total drag!!!

Has this been adressed?

ADOBE SUPPORT PLEASE! This is no how a professional NLE is supposed to run!

Only using 37 % of CPU and RAM...

I found that rendering through Adobe Media Encoder instead of directly through Premiere uses almost 100% of CPU every time! Also, choosing a good codec like Lagarith or Cineform plays a role in render time too.

I'm seeing the same issues on a 2013 mac pro. I'm rendering out a 60sec spot from Premiere at the moment that is mainly an AE comp dynamically linked. It's taken 40mins so far! CPU usage is around 10%

I'm rendering previews from Premiere + Cache and conformed media from AE to a RAID0 array. Media is on a seperate RAID0 array. System, drive is an SSD. Each drive can sustain at least 600mbps Therefore I think I can pretty confidently say it's not a HDD bottleneck.

I have done some testing. What i've noticed is that any codec that uses the AdobeQuicktime32 service cripples the PC. toneproductions‌ Since you're on a mac, i'm not sure what it could be for you. Is your AE comp using a lot of image sequences? That will bottleneck your RAID for sure. Also i found that rendering from my RAID0 (footage) to an SSD (render output) results in doubled performance as when trying to read and write to the RAID was creating a bottle neck.

Did anyone ever solve this?

I have gone from CS6 to CC14 having built a new machine.

I7 6x3.5ghz core

32g ram

2x760 graphics cards mated together

X99 mother board.

Render times are about 70% slower if not in CC14 and CPU usuage never goes above 10% - if I re install CS6 on new machine its super fast. Why is CC14 unable to use the power my machine has?

I just bought a new laptop i7 7700HQ, 16G RAM, 500G SSD. I installed CC Premium Pro and I'm experiencing a similar problem rendering on a only a fraction of the available CPU.

I have solved my problem. I found that, when running on battery, the power settings restricted CPU to 20%, which is what I was getting. I simply plugged in the power supply and within 30 seconds, the CPU was up to 80%.

I make this post because it may help others but it does raise the thought that maybe the lack of utilisation of CPU may not always be an issue with Premium Pro.

A bit of an old topic, but still the problem persists, I have both CS6 and CC 2014 on my PC, the exact same pproj file, same source, same hardware, CS6 in about 4-5 times faster than CC which for some reason only uses about 20-30% of my PC. Started encoding a video in CC's Media Encoder, 1080p @ 25fps 4hrs and 34min long. The encode is taking 3 days now. Just tried to do it in CS6, finished in 9hrs... Any ideas?

I just rendered out a a 2 minute sequence with about 100 clips in it and Colorista effects on everything to the Vimeo 1080 H264 preset. It took about 5 minutes to render straight from Premiere, it used all the recourses it could, my CPU was running at near %100, same with my ram and GPU, I was happy.

Then I did another render with Red Giant Denoiser and it now wants to take 30 mins and it is only using about %20 of the recourses available. My problem isn't that its taking longer with Denoiser but that its not using all of my computers CPU and GPU.

Im rendering at maximum render quality and bit dept to H264 (Im happy to wait the extra time), if I try to use VRB 2 it encodes 1 pass at a time and wants to take up to 40 minutes.

I would appreciate some advice on this.

This sucks... Question, are we all queuing to Adobe Media Encoder? Or exporting directly from Prem CC?
I noticed that when doing that you could specify either CUDA rendering or Software based. For my setup (Quad core i7 4770 + GTX 750Ti 2GB + 8GB DDR3 RAM) I managed to get my cores maxed out when in software mode taking 25mins for a 4minute 2-pass VBR 1080p mp4 (With Maximum rendering turned on), which came down to ~12mins when switched to CUDA, but only about ~25-33% CPU usage.

Note: haven't tried rendering in CS6..

Interestingly, just tried running a CUDA based BitCoin miner at the same time maxing out my GPU.. No real change in render times/mining performance..?

So personally I think CUDA Is being used fairly minimally..

Which begs the question as to why the CPU isn't being utilised more..
