Question

Much improved hardware specs not improving export time...?

My wife edits a lot of videos for her work. For the last couple years or so she has been using an off the shelf HP Envy Phoenix desktop -

Intel i7-4770 CPU (4 cores)

16GBs RAM

NVIDIA GeForce GT 640
SanDisk 480GB SSD Drive (Cant remember the exact one).

When she would encode a video it would max out the CPU to 100% and use around half the RAM. A 10 minute video would take around 2+ hours to encode.

She recently had me build her a PC in hopes that it would reduce encoding times -

Intel i9-7900x CPU (10 cores)

Corsair 32GB DDR4 (2x16)

NVIDIA GeForce GTX 1080 Ti 11GB

Samsung 850 EVO 1TB SSD

ASUS PRIME X299-A Motherboard

When she tries to encode a 10 minute video now, not only does it not take less time, it actually seems to take more...

She used a video project she knew took 2 hours to encode on the old PC, encoded it on the new PC, and it still said it would take 2 hours. After a couple hours of internet searches and checking settings to try and figure out why it didn't seem to be improving the encoding time, we decided to leave the video to encode for a while to see what would happen. We went and watched TV for a couple of hours, came back, and it still said 2+ hours remaining even though the video had progressed to around half completed... so apparently it at least doubled the encoding time that her old desktop would take.

We're both very confused.

We've done searches, messed with settings, made sure all drivers are up to date, and tried old versions of Premiere (in the past, an update caused encoding times to go way up) but nothing has made a difference.


The settings are set for CUDA accelerated. Ive tried doing a clean install of the GPU drivers, Ive updated the motherboard BIOS, Ive messed with various BIOS settings for the CPU (all things Ive had people tell me to try just to see what happens) and nothing.  I ran a benchmark test of the PC because someone told me there may be something wrong somewhere, and the results seemed good to me (not that I really know what Im looking at).  A 10 minute video is still taking well over 2 hours to encode.  The CPU is a little more than half used, RAM is a little less than half.


At one point she started a completely new project and didnt put any kind of effects or anything in it, and the encoding time was the same on the new and old computer. The old computer actually seemed to be a few minutes faster.

We both expected far better results out of this new PC, and needless to say shes very disappointed.

So what am I missing here?

Thanks.

    I havent been able to get on the new PC for a while.  It hasnt felt quite as urgent since we replaced that plugin that increased the encoding time by hours.


    But there has been a strange development.  My wife was recently encoding a video and using the computer while it was encoding.  I think she was transferring files to an external hard drive while using the internet. The computer froze up on her while encoding and a hard reset was performed.  She had to start the encoding over again because it hadnt finished, and when she did she told me the CPU was being fully utilized now.


    I checked and every core was being fully used.  In a previous post I had checked and half of them werent.  7 were barely being used at all and a few more just werent being used fully.

    We got our hopes up, but further testing showed that the encoding time wasnt actually increased.

    So I dont know what thats all about... I thought it was strange though.

    Well we made some form of progress yesterday.  Turns out one of the major culprits was a plugin my wife uses when she edits videos.

    We knew it was the reason hours were being added to encoding time, because one of the various things we did while trying to figure out why encoding time didnt change with the new machine was to take a project and see how long it took to encode without using that plugin - on both the old and new computer.  The time went down by hours, but still took the same amount of time to encode on either machine.

    She ended up finding a new plugin, and it cut the time down to basically how long it took to encode without the old plug in there at all.  The GPU basically handles it like its not even there, I guess.  So, thats good, times were cut down by hours, but at the same time its clearly taking "way" longer than it should be taking to encode videos as it takes just as long as the old machine. 

    DavidROfficer6198​'s advice is that its Windows 10 not fully utilizing the CPU, and using Windows 7 may help that.  I still have to try that because I need to put a DVD drive in the new computer.  I didnt bother buying one with it because we never seem to use them.  I dont doubt that suggestion, but Ive had people telling me that theyre using Windows 10 and are getting better times than me, so I dont know what to make of that.  Plus my wife isnt too keen on moving back to Windows 7, but is willing to if that actually makes enough of a difference.

    Other than the Windows 10/Windows 7 theory, I have yet to figure out why this particular PC isnt encoding any better than the old PC.

    So, I have to ask... and I know Im reaching here, because its kind of the point that Ive gotten to, is there any chance that maybe my CPU is "malfunctioning" in some way without any signs?

    The PC runs fine and I havent encountered any errors at all that would lead me to believe something might be wrong, but I thought it might be worth asking if its possible.  I considered exchanging the CPU just for the hell of it to see what would happen.  But, like I said, I know its kind of just reaching.

    I don't think the CPU is malfunctioning. You'd have a lot more issues if it were. Is there any way you could stick with Windows 10 and install the Anniversary Update and not the Creator's Update? I never tried that but i've seen all sorts of comments on the update.

    I still maintain that i had virtually the same results using Windows 10 Creator's Update with encoding not fully utilizing the cores and switching to Windows 7 solved the issue.

    Saw on another thread. Try creating or modifying a file called "cuda_supported_cards" and putting it in the  Premiere Pro directory?

    That is for CS6.

    I know but it helped on the other forum and i assumed he wasn't running CS6

    Your problem kept me from sleeping so here I am at midnight.

    I will describe your situation with one of our dear departed Harm's similes.  Your old system was like a Volkswagen Beetle, your new system you dropped in an i9-7900X Ferrari Racing engine into your new one and supercharged it with a GTX 1080 Ti, then you ued an aerodynamic body with 32 GB of RAM.but the bottleneck problem is you used the same type single SATA III SSD for the transmission and differential.

    I consider it a sin that you do not have a new super speed M.2 PCIe x4 SSD like a Samsung 960 as a SECOND SSD device for all your Adobe project files and media when your motherboard is perfectly set up to use one.  There also are tuning steps that you have to perform to get the maximum horsepower out of that wonderful new computer.

    Go ahead and run PPBM and Submit me the whole snapshot file (not a screen grab) as I can help more with the data in that file.  A ASUS feature is AURA, turn it off! as a starting point.

    Thanks for the reply!

    I will run PPBM tomorrow and get the results back to you.  My wife has been editing on the PC all day so I haven't had a chance to sit down with it and really try anything, and there's a video encoding right now that's going to take 8 hours.

    As far as the SSD, I dropped that one in there because its was all I was really familiar with.  I didn't know what M.2 was until I bought all the parts and started putting all this stuff together.  I'm not computer illiterate or anything, but I'm not really in touch with everything like I once was either.

    But since we've been trying to figure out why the encoding hasn't been improved at all, I've been reading about better ways to run your system for video editing (like having the second drive for project files and media), but the thing is, those are just ways to make it run BETTER, right?  I figured once we figure out what the problem is now, I could help her squeeze more performance out of it later, but when you say the SSD is the bottleneck, do you mean its the reason we're seeing the performance we're seeing, or are you saying it could be set up a lot more efficiently than it is?

    Because I'm aware that I'm far from an expert on these matters, so I could very well be wrong in assuming this, but I really thought we would see some kind of noticeable improvement going from the old system to this new one, even if she is using the one SSD.

    The issue here is that Adobe Premiere is not making use of the full power of the pc because it is not prepared and ready

    for that power. For now the 5960x and 6950x are the best for Premiere. Going to the 7gen is an invitation to editing headaches


    But not everyone can afford those CPU's and for those at home like these people, they can get decent results by preparing their machines. A simple dedicated drive for video storage should make a fair difference here.

    Upgrading like he did will make a world of difference. I know it did in my case and i'm only running a GTX 950 with Ryzen 1600. Only difference is i have 2 drives for video and Windows 7 which is way better than Windows 10

    Download and run my Premiere Pro BenchMark (PPBM) and Submit the results.  PPBM has three timelines but four tests which stress your CPU, GPU and Storage hardware using Premiere Pro.  With that data we can tell a lot about your setup and correct anything that may be causing problems.  I will be delighted to see my first test results from an i9-7900X
