Video Production only using 30% CPU

Hey there,

I recently upgraded my hardware from an i5-2300, gtx 560ti, w/ 8gb ram to a xeon e3-1231, gtx 970, and 16gb ram



There's a nice increase in video production speed thanks to the upgrade, it's about twice as fast

The weird part is that total CPU usage only goes up to around 30% while producing video, shouldn't it be utilizing more of it to produce video more quickly?

The current speed is approximately real time while producing 1920x1080 wmv.



Would a different production format better utilize resources?



All help is greatly appreciated

The gtx 970 is accelerating the encoding, taking load from the CPU.
You can check that with GPU-Z.

Now... can it be better? Maybe... hopefully on Windows 10 the software will be able to catch-up and take advantage of newer video modes.

That's probably about right for wmv. If you want to push the CPU harder, the H.264 1920x1080/60p (28Mbps) produce profile should get the CPU usage up there.

Highly unlikely, the GTX970 does not accelerate straight up wmv encoding process.

Thanks for the reply. I donwloaded gpu-z but it's saying the graphics card isn't doing much either. (~3-4% for gpu load and memory controller load)

Tried it, still only 20-30% cpu usage. Thank you though :)

20% for H.264 appears very odd to me. If you want, drop 10 boats.wmv in the timeline and produce to the H.264 profile suggested and post a screen dump of produce settings and CPU load as well as a dxdiag (type dxdiag in start menu search bar) of your system to look at a few other components for some possible ideas.

Even if you have Hyperthreading on, the H.264 profile suggested should have been higher than 30% based on my experience.

Dxdiag is attached

I'm kind of getting the sense that windows/some other part of my system isn't fully registering my new hardware. (I'm having some other minor issues as well)

I'm considering cloning or backing up the main drive and then doing a fresh windows install to see if that helps things.

Yes, I think you have some issues. If you look at the CPU load you see every other CPU at 0% load, those are all the Hyperthreaded cores. So your avg load appears rather low as you have, 50%, 0%, 50%, 0%....so when one averages over the 8 threaded cores you get ~25%.

A typcial chart from my experince would be more like the attached.

Ah I see, that's very helpful thanks

I have the same problem in PD17, video producing fails to utilise available system resources:
