Question

CPU usage only 40-50%

Hi!

Please, can could someone tell me, how it is possible that Premiere Pro uses on Warp Stabilizer only 40-50% performance of my Intel i5 4690k? I read somewhere that warp uses only 1 core, okay, but why only 40-50%?!

🙂 Memory usage is about 50%-60%, SSD - 1%, GPU - 3-10%, so there is no bottleneck, then, where is the problem?

Thank y.

IM gonna Hijack this old thread aswell. 🙂

I have an overclocked 9900k 5 ghz on all cores running stable on stresstests with max 80 degree temps on full load. And just before I moved to a new apartment, premiere pro always used 100% cpu. It even made my cpu crash sometimes before I got the voltage stable for OC and exporting went fine. But now when i moved to a new place and I updated premiere pro, CPU load is about 40-50%. Its a 34 min long video 1080p with 2 frames side by side (reaction video format) with lumetri on an adjustment layer on 1 of the frames. 20-25 min export time.

Now, is this normal? Shouldnt CPU load go to 100% and export faster?

My brother used to complain loudly that the pinball machine we were using always knew when it was he that was playing and he had all the bad luck! 🙂 Perhaps your computer doesn't like the new place and is trying to express that? 🙂

The CPU/GPU use what they need. If you are going to try and fry the internals with 80c temps, turn your cpu up to 100% and give it a try. You can do that in "Power Options", set the Minimum processor state to 100. I don't recommend this though cause it sounds like your machine is working correctly.

I do admit that this was a fun post. 😄

But I do not really think you know exactly what you are talking about since power state has nothing to do with CPU load.

I just dont understand why the cpu all of a sudden would sit on 50% load. Feels like something with premiere pro update but if no one else has experienced this, I guess I have to keep on doing research.

I'm late to the discussion but what you're experiencing is normal behavior for Premiere Pro. I've got a 10-Core overclocked CPU with a 2080 Ti, and 1080p exports generally only cause about 25-60% CPU usage for me. However, when I export a 4K timeline to a 4K h.264 file, my CPU gets pinned at 99-100% nearly the entire time.

Try getting some 4K footage and exporting that to h.264 and see if you get higher CPU usage. If your CPU usage goes way up then you're likely not experiencing a bottleneck and it's just Premiere not being able to use all of your CPU when it comes to what you're working on.

As far as GPU usage goes, mine is all over the place and goes anywhere from 10-40% usually. I didn't notice much, if any, decrease in render times when upgrading from 1080 Ti to 2080 Ti. Premire doesn't do the best job of harnessing GPU power the way Resolve does.

Thanks for that info Tony.

Yes, that's pretty much the way it is. If you want to see your GPU being used, do some scaling, like creating proxies. When making 720p proxies from my 4k footage, I can peg both my CPU and GPU. Here's a screenshot of Task Manager while doing such:

PP does use the GPU when scaling footage. See this adobe page:

It just uses as much as it does. I don't think there's anything you can do to significantly boost it to make is quicker. In Windows power settings you can have your CPU run full time @max, using a bunch of power and likely getting really hot, same with a dedicated GPU, you can turn them all up to 100%, even when nothings happening. I tried that when I was in the eval/benchmark mode checking my new build, but there was no significant performance improvements, just made the machine loud due to the fans all running at top speed, and using a bunch of power for everything.

I'm sure you don't need a 2nd drive. That 970 is quite out of place in your mid-level system from 2014. I think the answer is 'that's the way it is'. I wouldn't recommend you spend much more on the hardware for that machine. That's how long it takes.

With warp it's intended to help fix short clips so if you are using it on minutes long clips, you might want to consider a stabilizer for your camera.

I make real estate videos, with a stabilizer I do a lot of work, but, the whole clip I need to have an extra smooth run. That's why I'm using in final the warp stabilizer. So, the answer is that there's no chance Premiere will use all the processor power to analyze?a

What is your hard drive setup (how many, what kind, what is on each, and how full)?

I have one disk, Samsung EVO 970 - 1TB, have about 70%free. I think there is no problem.

But where? 😞

Try adding a second SSD.
