Question

Low Usage of CPU and GPU

Already downgrated versions, did update on all my drivers and when it comes to rendering a 2 hour long video, it takes like 6 hours+?

I use a Ryzen 9 3900x, RTX 3070 and 32 GB RAM.
Something isnt right.

I've downgraded to every version I could find. This last 3 hours I was testing render after render, 14.4 used 50% of CPU and 60% of GPU. 
I think that should be enough for now...

It would still be nice to know what media you were working with. Different media presents different issues for exporting. 6k RED 8k very different from say 4k H264. They need really different things.

 

And some systems that struggle with the RED do fine with H.264. And vice versa.

Oh, just simple 1080p h.264.

Assuming your sources are h264 / h265 .. 

1) Do you have VFR footage on a timeline? Use MediInfo tool to check. It's highly recommended to transcode such clips to CFR before editing. Tools people use: Handbrake, Avidemux, ffmpeg, nvencc, or even build-in Windows editor
2) Try to turn off Hardware accelerated DEcoding in Preferences > Media... It's recommended to clean media cache each time you change this settings, and after any app update as well. Close PP and manually clean media cache (goto %USERPROFILE%\AppData\Roaming\Adobe\Common and clean/delete folders: Media Cache, Media Cache Files, PTX, Peak Files)

I've already cleaned the cache many times, i don't think that is this. 
I'll try Handbrake.

Some people have mentioned turing off Nvenc for encoding and decoding helps.

What effects do you use in that video? Any Warp Stabilizer, video noise reduction, major color work or speed ramping?

Hi,

Is this H.264 source and H.264 export? Or are other formats involved? Where do the source files originate? Have you updated your video drivers lately? Let us know.

 

Thanks,
Kevin
