Premiere Pro CC (2018) bottleneck

Hello guys,

So i've got 3 questions:

1. Is everyone experiencing CPU bottleneck with Premiere?

We mainly edit 4k h264 footage from DJI X5 RAW camera @ 60Mbps

I know premiere is more CPU intensive in every way but i hate it so i have to make the rig work better.

With the GTX 1080 i 've found that encoding times and render previews worked faster for a 1080p timeline and export.
With the Radeo Pro Duo i 've experienced kind of slower exports (without resetting profiles) and render previews to about 20 seconds difference.

Though i think that i get slightly better timeline editing performance with the Radeon.

I really don't care about exporting time (reasonable times of course), my main concern is the real time timeline editing performance which i believe that's what all benchmarks should also include but mostly they don't. Also not including AMD professional cards is also very suspicious.

What i 've seen within premiere is that the CPU is hitting 100% load quite often especially on rendering and exporting while the GPUs just occasionally being utilized for a fraction of a second at about 5-10%.

2 .Is there a way to eliminate the bottleneck on the current configuration?

After effects can't fully support the Radeon Pro Duo though i get really good realtime performance with particles and stuff. The radeon also performs far better than the GTX 1080 in Photoshop 3D mode while one of them GPU 0 being utilized at 45% max and the cpu stays at 20% max.

My next question is:

3. Will an AMD Threadripper 1950x solve my problems with Premiere and help me edit without any glitches or slow framerates in timeline based on my current config or does the problem rely on the DJI footage no matter what cpu i add?

EDIT: I know that using proxies would be a way to go but i'm trying to understand if i can get it to work without them.

My instinct says it will but i need some help to be sure.

My configuration:
X99-Ultra Gaming
Core i7 6850k @ 4.2Ghz

RAM Corsair Vengeance 32GB 3200Mhz @2933Mhz
Samsung 850 Evo Sata SSD (Boot)
Samsung 960 Evo Nvme (Scratch & Projects)
Samsung 950 Pro Nvme (Footage)
GTX 1080 Gigabyte G1 Gaming 8GB (previous)
AMD Radeon Pro Duo (Polaris) 32GB (current)

I am waiting for a reply from Samsung about the problems we are having. I also tried crystal disk mark and HWInfo showed that the 960Evo was going to 95 Degress Celsius therefore i stopped it.

Anyway i overclocked the Core i-6850k to 4.3Ghz with higher voltage and it gave me 4 seconds less on the H264 test.

Then i used my 4k DJI Footage on a 1080p Timeline and applied some directional blur effects.

While playback and realtime effects changing i saw the CPU staying at 20% load and the GPU0 at 55%.

Though when exporting to h264 CPU was at 100% load and GPU at 1% (only my monitor was giving the load i guess)

What the hell is up with that?

I also tried exporting to MPEG2 Bluray and the CPU stayed at 30% load while the GPU at 1% therefore the exporting time was increasing.

I am very confused. Am i missing something?

Ok so Samsung really messed up with our drives. We just have to wait for an update? Is there a way to contact support for the ssd's?

But that is not the question of this topic.
Would and AMD Threadripper 1950x improve my workflow based on the current footage we edit or would i need to ingest with that CPU as well?

Would i see the GPU utilizing more with the threadripper?

First of All i don't understand a single word. This is already enabled but the GPUs don't utilize compared to the cpu and of course there is no problem playing back a single file even with lumetri (live changing while playback) and 3 effects on top (depending on the effect)

There is another way. Transcode to a media form that is easier on your CPU. Your media is a long GOP media which requires an awful lot of CPU to generate each and every frame. Cineform media which is much easier to edit is the way to go. Try the GoPro free version. It is a very high quality industry standard format, the only real disadvantage is that because you have each and every frame is there, your media files will be much larger. I do not have a link but just search these forums for help

Unfortunately, Bill, the Cineform encoder is no longer available for download directly from GoPro, as the program that included it (GoPro Studio) has been EOL'd three months ago. And the last version of GoPro's Quik desktop app that included GoPro Studio was version 2.3, which is also no longer available for download. Beginning with version 2.4, GoPro Studio is no longer included with Quik. And although GoPro will continue to support and update the Cineform encoder, no current or future GoPro software products will include it.

By the way, Premiere Pro CC 2015 and later (including CC 2018) includes a Cineform encoder, and that encoder should have been installed as part of the installation. Plus, since at least CC 2017, Premiere Pro should have given the OP the option to use proxies or transcode upon import (ingest). Cineform MOV presets are included with this feature.

Follow these instructions:

I guess something changed in CC 2018 to see the Step 3 instructions. I had to advance the CTI in this window, previously you could advance it in the real timeline and it would come up when you did the Ctrl M

This is what Samsung has replied:

The 960 EVO is a TLC based device which has something called Turbo Write which uses a cache that is placed on the drive to provide the fast speeds. When the cache is full your writing to the NAND directly which results in lower speeds. However this temporarily and once the cache is empty the write speeds go back up. Going based off the results of these screen shots there is no present error occurring with the drives and this is completely normal. The numbers in Samsung Magician also show consistent results.
