  • Primary Colour Correction GPU assist makes it worse!

    Hello

    Just tried a 50p 10Bit 3840 by 2160 project on system 4 with both WG8 and WG9 and added Primary Colour Correction onto a 50p XAVCI clip and Edius can't play it without stutters. Very disappointing.

    Turn off GPU Acceleration in Primary Colour Correction Settings and Edius can now play the clip.

    I think this means that the way the GPU acceleration is applied is not correct, especially as Premiere Pro cc2017 on the same hardware is perfectly happy to play 9 layers 25p PIP (10 layers total) over full screen background layer with colour correction applied to all layers, the GPU is running at about 85%, I will have to set up a 50p test and see what PPro it can do with that.

    (GTX980TI STrix)

    On a single layer of 50P in Edius; -

    I show 41% CPU on 50p XAVCI no filter 73% with Primary CC on no GPU.

    I show 42% CPU on 50p XAVC Long GOP no filter 74% with Primary CC on no GPU.

    Won't play either in real time with GPU on in settings and Primary Colour Correction filter on.

    Pre load buffer CPU shows 42% GPU shows 39% buffer rapidly counting down with GPU on.

    Edius 8WG and 9WG are both the same.

    What can be done about this issue please?

    which OS? If Win7, you must not enable GPU acceleration of PCC

          It is also important to check if you card supports the resolution or bit depth.
          The GTX980 Ti seems to struggle with frame rates at 50p and above. (according to different review sites)

          Also check if the bit depth of your project is supported by your card. Some cards accelarate 4k at 8 not at 10.

          In 1920x1080 most recent cards will give rather good performance but at UDH/DCi 4k you need a rather recent card.

          Just some info.

          I will check with QA if you cards in your signature are good enough for the resolution.

            To Anton I only use NVidia Drivers never Ms ones.

            To Steve hmm good question.

            Specs are here

            https://www.asus.com/uk/Graphics-Car...pecifications/

            It doesn't tell me what you asked.

            It's updated alternative could be

            https://www.asus.com/uk/Graphics-Car...pecifications/

            WE can say that the 1080TI supports twice the resolution that the 980TI supports and NVidia say at 60Hz.

            The internal processing 8 or 10 bit remains unanswered but some web reading suggests it is only on the pro Quadro cards, but others suggest it is also on the GTX cards, but comes down to the monitor capabilities the card is connected to.

            My Nvidia Control Panel only shows 8bpc as being available and I am using 2 off HP LA2405x 24 inch monitors which are specified as 16 million colours which I believe translates to 24Bit colour, the card is set to 32bit.

            The 10Bit monitor is a bit of an expensive rarity. The HP z24x at £588 per unit and I would need 2 of those, but that uses 8bit to 10Bit FRC simulation and I am happy with 1920 by 1200 rather than UHD set on each. Dell do some as well but tend to be 27inch.

            So I haven't determined yet whether it is necessary to have 10bit monitors connected or not, and expensive experiment just to try it.

              For what it's worth, if you have Windows 10 Fall Creators Update Build 1709 or later, the Performance tab in Task Manager can now show you GPU activity.

                I use free app Open Hardware monitor and select CPU0 & CPU1 load, RAM load, GPU temp, GPU Load, GPU fan and add each the sensor active icons onto the task bar.

                  Ok now some detailed test results for you in the PDF attachment with GPU assist on and off for the Primary Colour Corrector (PCC).

                  GPU=ASUS GTX980TI STRIX

                  In both HD and UHD the GPU assist is worsening the performance instead of enhancing it, which can't be as intended.

                  The PCC filter itself is very good it doesn't drag down the performance.

                    Have you tried moving the video card to a different slot?

                      My ASUS MB block diagram is attached

                      No I haven't tried the GPU in another slot, it is in the default position of PCI 2 it could go in 4, 5, or 6 as they are all x16 slots but it will cause a card shuffle as all slots are currently filled. The original card has been replaced it was an Nvidia GTX980TI this one is the ASUS STRIX version.

                      The standard test patterns all pass on the GPU

                      1=Sonnet Tango 3 USB3/IEEE Firewire 400/800
                      2=GPU
                      3=blanked out by GPU
                      4=Grass Valley Storm 3G PCI extender
                      5=Atto FC41ES HBA Fibre channel card
                      6=Decklink 4K Extreme 12G card

                      There doesn't appear to be any slot sharing issues to consider for the x16 slots, and certainly Premiere Pro is happy with the GPU in its current slot (which is the default slot) including NewBlue plugin GPU acceleration.

                      However in Edius, GPU acceleration enabled for NewBlue plugins, that crashes Edius but the plugins work fine without. But some that could be real time with GPU enabled are not, without first rendering. The GPU card replacement mentioned above, admittedly installed in the same slot, did not change this problem.

                      So I think there are two issues on system 4, I see with the GPU, the NewBlue issue isn't present on the older HP dual Xeon systems with the dual 4 core X5492 Xeons, but I should make the same test on the Primary Colour corrector on one of those too for a comparison.

                      So I have just paused and done that test. That PC has an NVIDIA Quadro 4000 card. HD 1080i project. 4 seconds to fill the buffer (250) 8 seconds with PCC applied, and 11 seconds with GPU acceleration, so that completely different set of hardware is producing the same results.

                        Hello everyone, when assembling a new computer, I faced the same problem - 1080ti hardly gains a buffer even with one Primary Color Correction :( Drivers of the latest version from nvidia.
                        Haven't figured out which way to look to solve this problem?

                          We just have to face the fact that Edius is not optimized for GPU usage, like Anton says you"ll need all the CPU power you can get. I have a 5950x which can handle 5 streams of 4K 25p mov files in a multicam with "ease" with CPU usage of around 80% until I start to add PCC and then the fun is over, on the same pc resolve studio runs circles around Edius with hardly any CPU usage but full GPU usage (a rtx3060ti). In Edius my pc fans start kicking in during a multicam, in resolve my pc is dead quiet doing the same while being able to handle all colour corrections without breaking a sweat.

                        if your CPU is powerful, you don't need GPU

                        I have GPU for PCC disabled in system settings because print to file is way faster with it disabled, all 32cores work at 100%
