Hi Everyone

So I have been having issues with Premier Pro, After Effects and Encoder on my new PC . This seems to be a big issues as I see this problem on forums and discussion boards across the internet and while some have fixed it or made it better there is no definitive global fix. It seems to get tossed up to hard drive performance which I am stating is false. Unless I am proven wrong - I hope my findings will help further push for a solution

This happens equally with 2015.3 and 2017. I do not use 2015.5 (too many bugs but same performance issue)

-- Computer Specifications ---

HP Pheonix Envy 860
Fresh CLEAN Windows 7 Professional 64x Install 10/22/16 - Fully Operational 10/29/16 (Did not use HPs Recovery Disc set)
i7 5820K 6 Core 12 Threads (O.C. 3.6Ghz) - Liquid Cooled
24GB Ram 2133 Mhz DDR4
NVIDIA GTX 960
2x 2TB Seagate 7200 RPM 3.5" HDD SATA 3
- - C: 1x OS / Programs
- - E: 1x Media Storage
1x 750 GB Toshiba 5400 RPM 2.5" HDD SATA 2
- - G: Export HDD
INSTALLED ADOBE VIDEO SOFTWARE
- Premier Pro 2017
- Premier Pro 2015.3
- Encore CS6 (Uninstalled Premier Pro CS6 - Only needed Encore)
- After Effects 2017
- After Effects 2015.3
- Encoder 2017
- Encoder 2015.3

I am making a case as people always say that its the amount of hard drives in the computer or the fact they are 5400rpm vs 7200rpm or your not using a SSD for your OS, or your Adobe Cache is not on the correct drive and adobe heavily utilizes this cache during exports (which I found to be false on my PC)

So I ran a battery of comparison test and more to come... I compiled all the tests down to 4 below.

-- 1ST SERIES OF TESTS --

Specs during test
2x 2TB 7200 RPM HDD
- C: OS / PROGRAMS / CACHE

- E: MEDIA STORAGE / EXPORT
NO 750GB HDD

Original Video File: 6.5minute 1080p 50Mb/s bitrate. MP4 XAVC-S

Exported Video File: 6.5 Minute 1080p 40Mb/s bitrate H.264 - No effects
CUDA HW Accel PROCESSING ACTIVE

Exporting video file from Premier Pro / Encoder

According to Windows Resource Monitor

Adobe READS from E: MEDIA STORAGE @ 4.5MB/s
Adobe WRITES to E: MEDIA STORAGE at 2.5 - 3.5 MB/s.
CPU 45%-50% Spikes of 60%-70%
GPU 1%, 5%, 25%, 50%. Spikes of 100% every few seconds for a split second (Varies to much) Average I would say is 20%

Changes and Adjustments

Moving Cache from one drive to another made ZERO difference.

Exporting to one drive or another made ZERO difference

-- 2ND SERIES OF TESTS --

Specs during test

2x 2TB 7200 RPM HDD
- C: OS / PROGRAMS

- E: MEDIA STORAGE
- G: EXPORT HDD (Added to test if an additional drive would help) Specs for drives at TOP of post

- F: 256GB USB THUMB DRIVE (USB 3.0)

Original Video File: 6.5minute 1080p 50Mb/s MP4 XAVC-S
Exported Video File: 6.5 Minute 1080p 40Mb/s H.264 - No effects
CUDA HW Accel PROCESSING ACTIVE

CHANGES & ADJUSTMENTS

Moving CACHE between 3 drives had ZERO effect. In fact, No cache activity was reported during exports when one drive was strictly used for cache only

Image Below shows export writes at 3.3MB/s to MEDIA STORAGE E: (Media reading from E: as well) while CACHE was moved to G: - Notice....G: has ZERO activity during exports in this test

Test 1 - Export from Premier Pro to G:

Exporting video file from Premier Pro / Encoder

According to Windows Resource Monitor

Adobe READS from E: MEDIA STORAGE @ 4.5MB/s
Adobe WRITES to G: MEDIA STORAGE @ 3.5 MB/s.
CPU 45%-50% Spikes of 60%-70%
GPU 1%, 5%, 25%, 50%. Spikes of 100% every few seconds for a split second (Varies to much) Average I would say is 20%

Test 2 - Export from Premier Pro to G: while Copying a 34.8GB video file FROM E: MEDIA STORAGE to USB THUMB DRIVE (USB 3.0)

Exporting video file from Premier Pro / Encoder

According to Windows Resource Monitor

Adobe READS from E: MEDIA STORAGE @ 4.5MB/s
Adobe WRITES to G: MEDIA STORAGE @ 3.5 MB/s.
FILE COPY WRITES to F: @ 80+ MB/s
FILE COPY READS from E: @ 80+ MB/s
CPU 45%-50% Spikes of 60%-70%
GPU 1%, 5%, 25%, 50%. Spikes of 100% every few seconds for a split second (Varies to much) Average I would say is 20%

Test 3 - Export from Premier Pro to G: while Copying a 34.8GB video file FROM USB DRIVE (USB 3.0) TO G: at same time

Exporting video file from Premier Pro / Encoder

According to Windows Resource Monitor

Adobe READS from E: MEDIA STORAGE @ 4.5MB/s
Adobe WRITES to G: MEDIA STORAGE @ 3.5 MB/s.
FILE COPY WRITES to G: @ 80+ MB/s (Windows Copy Window says 200+MB/s - confusing)
CPU 45%-50% Spikes of 60%-70%
GPU 1%, 5%, 25%, 50%. Spikes of 100% every few seconds for a split second (Varies to much) Average I would say is 20%

From these test, I find that the hard drives are not at fault and 3 drives make little difference than 2. If adobes encoder worked the way it should, more drives might make a difference, but in this situation, adding another 3rd drive did not make any major difference...only about 1MB/s write/read. I was able to copy and export to the same drive which made no difference in encoding time or encoding read/write speeds. Which tells me the HDD and SATA system is not choking.

Moving CACHE from one drive to another made ZERO difference. Adobe Encoder seems to not use CACHE during exports. Probably only for Renders.

Can anyone tell me what the heck is going on? I bought this PC thinking I would get insainly fast exports as I have very important TV Show work to do and I can barely preview edited work with minor effects in real time or export in any reasonably timely manor. I also wanted to export in 4K.....it takes unbelievable amount of hours to export in 4K which it shouldn't.

I am going to compare my results to more test I will perform on my i5 Laptop I used for encoding before.

My concern is a little different. I'm currently rendering a small video using AME 2017. I've 'ticked' the 'Mercury ... CUDA' render option but notice that my CPU is running at about 94% for AME while my GPU Load is napping at 0%. As a side note when I use 'Blender' to render projects the results are flipped. CPU cruises at regular usage while my GPU is humping.

This leads me to wonder if AME is either ignoring my CUDA settings or Adobe CUDA usage is a cruel joke.

What your post sounds like is that you simply don't understand the use of the GPU in Premiere. Every video-post program I know of seems to use the hardware differently.

There's a list of GPU-accelerated effects for PrPro, and over time that has been expanded. But it's still mostly things like Lumetri, Warp Stabilizer, some other color effects, and frame-resizing. So for part of you exports, your GPU may spike to flat-out, then quickly go back to near-zero, depending on what's being encoded at that moment.

Here's the link to the current list:

Thanks for the information. I guess It annoys me that I'm left with the mistaken impression that the CUDA (GPU) 'option' versus 'software only ( CPU)' means just that. I'm imagining that rendering of my project will be, more than less, handed off to the GPU. Going strictly by the labeling of the options one can be forgiven for having this impression. Adobe has too many, under the hood, stipulations for my simple minded sensibilities.

Blender takes for ever to render, but when they say GPU rendering, the monitors show that's exactly what's going on. My CPU is free for other things. I can render a project and, at the same time, watch movies or You Tube videos etc., whereas Adobe pretty much 'owns' my system for the duration.

But, thanks again for your response and info.

From what i gather the plugin is only using features available by adobe. The plugin just uses these features in a certin way. If thats true than adobe should be able to render or encode faster. If thats not correct than ok.

The point being adobe can be more efficient. even without using 3rd party plugins adobe acts the same way.

I hardly use plugins. I will more in the future.

So now you are expecting Adobe to make third party software work up to your desires????

There are a few other tests I want to do with my new system. Now that I noticed a project in After Effects 2017 rendering in the timeline faster after moving cache and conformed media to my m.2 nvme ssd. I want to swap the cache and conformed media around to the slowest drive and see if it makes a difference.

I also have my major media files on a 4tb RAID 0 partition which tests at 413MB Read and 380MB write. According to windows there is usually less than 10MB/s being moved around from any drive in my system so It should be interesting.

I am also going to run Adobes Benchmark File that I couldn't fully run before and see what the numbers are.

I wish I had both systems running. Someday I will upgrade to either a 5960x 8-core or i7 6950x 10-core knowing Adobe might not utilize all the cores. Then use my left over parts to upgrade my AMD A8 3870k Movie Server to a Intel i7 5820k Movie/Render Server. Premier Pro seems to utilize multiple cores better than After Effects.

MODERATORS: Could you move this to the HARDWARE section of Premier Pro please?

Well if you really want to see your CPU and GPU usage measured you will have to go back to Premiere Pro BenchMark (PPBM) and run it. Just for you I "crippled" my i7-5960X to look like your i7-5820K. So running with 6-cores at 3.6 GHz here is what happens when the CPU intensive MPEG2-DVD timeline is exported without GPU assistance:

.

Notice 6-cores at 3.57 GHz and 100% utilization

Next, when you enable the GPU acceleration with my GTX 1060 SC at stock speed, here is 99% utilization

See the GPU Load above.

Now for the scores.

"24","81","23","414", Premiere Version:, 11.0.0.154, simulated i7-5820K at 3.6 GHz with the GTX1060 SC

TBA more comparison scores and explainations

Sorry have to run will finish this later this evening--I have to run right now.

You guys are awesome. This is the type of "other possibilities" I'm looking for. I"ll check all this out and get back to you on my findings.

RoninEdits

Thanks to both of you!

If anyone else has other information please post it.

GPU usage most of the time is between 1%-7% at any point in time. Sometimes it does get to 25% or even 50% for a split second but doesn't last. Once in awhile it my peak 100% for a split second. Most of the time the GPU is idle and the CPU is under 50%

PrPro doesn't use a GPU much during export/rendering except for things on the "GPU accelerated" list ... the Lumetri panel corrections I think are on that, I know say re-sizing is ... some other things. If you're not running those things, the GPU isn't involved. The rest of encoding is a CPU process.

As to the rest of your questions, I think RoninEdits or Bill Gehrke would have better thoughts ...

Hi there thanks for the reply

I do understand that not everything can run thru the GPU and its mostly thru the CPU. Though if the GPU sits idle, I would expect my CPU usage to increase drastically at least to 90% if not 99% during exports / render. Only time I would want to see my CPU lower is if the load is handed off to the GPU.

Export Times - No Effects or Editing

6.5 Min 1080p 50Mb/s Clip to 6.5 Min 1080p 40Mb/s = 10 Minutes
1 Minute of the same 6.5 min clip to 1080 40Mb/s = 1 minute

My main concern is the very slow read and write speads. If I were to export a 1 hour 1080p clip at 40mb/s it would take 1-2 hours....thats not right.

Adobe READS from E: MEDIA STORAGE @ 4.5MB/s
Adobe WRITES to G: MEDIA STORAGE @ 3.5 MB/s.

Only way I can get faster writes is Overclocking the CPU even more. Pushing it to 4.6Ghz on a HP China branded Motherboard - doesn't make for stable speeds but was able to achieve 5MB/s write speads which eventually slowed down to 4.5 MB/s write speeds. That is with adobe using 50-60% of CPU

I see videos online exporting MUCH faster...1 minute video exporting in 8 seconds or so..not sure there exporting settings....
