Premiere Pro CC 2019 uses only 20% CPU to encode heavy media.

Hello guys, i know the tittle probably sounds familiar to some of you, but my case is kinda different from what i saw in the forum during the last couple of days.

I got brand new beast pc and during work everything is more than perfect. I don't have any kind of slow performance issues (during the working process), but when it comes to the encoding part.. well.. things get a bit strange. I just finished my latest music video. 5 minutes long and my timeline have around 30 dynamic links to AE for basic smoke compositing. (Very basic masks, combined with "set matte" and "shift chanels"). The masks i made are with "Mocha pro". On the other hand i made, a lot of "beauty retouch" with "Mocha" on something like 40 clips. (In total) . But even thought during working i got no issues, everything goes suprisingly smooth.

The encoding part : My sequence is 1920x803 but i am exporting in 1920x1080. My footage is 1080p from Canon 80D and Sony a6300.

For the encoding i am using "H.264" with 1080p resolution, profile "high 5.1" , "Vbr pass 2 - 32 mbps bitrate" Aspect "Square pixels 1" / Rendering at maximum depth and "Use maximum render quality".

Premiere uses 100% CPU and, a lot of percents GPU, around 40-80%(seeing this for the first time, but newest "nvidia driver 419" seems to be the reason) during the encoding process, my RAM ussage goes maximum to 40GB but that performance applys only for the simple media. Where theres only pretty much only LUT's applied to that footage. When it gets to the point of encoding the dynamic link, or footage that Mocha were applied on i see how my performance drasticly drops down. CPU - 10-15% and GPU bearly 1-2% and my RAM drops down to 15-20GB. There's no difference if i do the encoding over "Premiere" or "Media encoder". I even tried to use "Render and replace" for all my dynamic links but there was no difference.

PC specs :

CPU : Intel core i9 9900K octa core 3.5/5.0 turbo boost

GPU : Nvidia GTX 970 Gygabite windforce 3.5GB (with newest driver)

RAM : 64 GB (4x16) Crucial ballistix sport 2666mhz (Adobe programs are configurated to use 60 GB)

SSD 1 : Samsung 970 NvMe evo plus 250 GB - For OS and programs

SSD 2 : Samsung 970 NvMe evo plus 500 GB - Separate drive only for adobe media cache. and project files.

HDD : 2TB SATAIII WD Red 64MB for NAS

Motherbord : Intel Z390 AORUS ULTRA

PSU : EVGA 850 B3

OS : Windows 10 Home edition, with most recent update. / My power plan is set to "High performance".

Turn of Max Render as you have a dedicated card.

See how that goes.

edit: why is 1080p set to 5.1?

What is the end destination of the footage?

You might have an 'underpowered' videocard in relation to the cpu.

I just tested it and still no difference.. I have 2 versions of the project 1 with rendered and replaced dynamic links and one with dynamic links without render and replace. Tried turining off the option for both versions of the projects, but the results reminds the same..

Linked AE comps are single threaded in PP, so what you're seeing is not surprising.

You'd get better export performance if you bypassed Dynamic Link and exported Cineform files out of AE for use in PP, but then you lose that simple editability that Dynamic Link offers.

You'll have to decide which is more important, exporting speed or making changes.

The render settings that i described are from, a youtube tutorial. Not sure where that video will end, but i assume it's no futher than youtube or vimeo.
