  • Edius X: Image errors with H.265 and NVENC

    Hello together,

    when I export my H.265 HDR HLG 4K 25p files from my Panasonic G9 using the NVENC encoder there are strange image errors created in the export file.
    These are notable as a lot of white pixels dancing on the screen. You get aware of this only in dark scenes of course.Please see the screenshot below.

    With Quicksync export (and the same settings) none of these white pixels are visible.
    I use normal standard export settings (75Mbit, 4:2:0, BT.2020) for both. No color correction or other effects are applied.

    What can be the reason for this phenomenon?

    Is nvenc generally not so good in quality in comparison to Qicksync or can it be a bug?

    I use Nvidia GTX1650 graphics card with latest drivers. As I upgraded recently to an intel i7-11700 CPU (and UHD 750 graphics) I additionally have the problem that export with Quicksync is now double the time of the NVENC export. With the old processor and UHD630 encoding times were nearly the same and therefore I never used NVENC before.

    Thanks

    Harald

    QS should be way faster, it could be that you are using an unsuitable driver, usually the one on the mobo driver disk will work

    I will test with some dark files

      I tested with dark files and could not find any imperfections after export

      I am using an RTX-2070 Super

        Ok, thanks! I also think there is a driver problem, unfortunately with both graphics cards.

        For intel vga I have the newest driver version 27.20.100.9415 (15.4.2021) whereas on the Asrock website of my motherboard the older version 27.20.100.9127 can be downloaded.
        Also with Nvidia I have very new driver version 462.31.
        Maybe I have to wait for next bugfix...

        In another post I also read that Edius X is not compatible with new iGPU UHD750 in intel's latest cpus. What a pity!

          On EDIUS, you will find that the decoding performance of uhd750 is less than half of that of uhd630. Even if the latest April 16 driver is used, we can only wait for EDIUS to update the SDK.
          From edius7 to ediusx, there is still no message supporting AMD and NVIDIA decoders, and the flowers I'm waiting for are withered.

            So, I have installed Edius version 10.20, but the nightmare unfortunately continues:
            • the image errors with NNENC export still continue
            • the H265 10bit export with Quicksync is a little faster then before (same timeline 26min instead of 33min), but still worse than with old desktop PC and UHD630 (20min).
            • the H265 10bit export with NVENC is now double the time (same timeline 40min instead of 17min)
            So at least it now longer makes sense to use NVENC, but as a conclusion, no problems have been solved with the new version. :-(

                  The latest drivers are not always the best so I would stay with the motherboards driver. Also I find that the Studio drivers work best for editing software on my system so driver for NVIDIA is 462.59

                    Why? EDIUS 9 is so much better if you do not want to go to EDIUS X.

                      In the meantime I have also installed Nvidia Studio driver 462.59 but doesn 't seem to help.

                        For now.. iam sticking with e7..... I have no issues with it. Edius 7 was a fantastic version of edius. for the amount of work I do, changing to E9 or E10 is just going to be a waste of time/money for now, I will move over to edius 9 or 10 oneday.... once better hardware is available for e9 or 10.
                        the only thing I cant do is edit/encode h.265 files with E7. no major drama for me as I have a program to convert those files if needed.
