Voukoder unable to initialize encoder RTX 2060 Super

1. offizieller Beitrag

    I was using Voukoder 2.2 perfectly with a Geforce GTX 970. This weekend I upgraded that card to a RTX 2060 Super wich I heard Turing was great with NVENC. Tried to encode a Premiere project but immediately saw the error of the subject. Geforce Drivers 436.30 are installed (clean installation using DDU). I tried VBR, CBR, CQ, disabling all options and leaving it as it is in default but got the same error every time.

    Non NVENC codecs works perfectly, only the NVIDIA hardware accelerated ones fail. :(

    Below the log data

    This has most likely to do with an invalid combination of options.

    Make sure there is at least one free NVENC session and close all other programs that make use of NVENC.

    Please check if the used options and presets comply to the selected output level. Even the encoders default configuration (no options set at all) might not comply with all levels.

    Nope as I explained no options make it work, not even leaving everything as default and unchecked. For some reason RTX 2060 does not work with NVENC on Voukoder (Handbrake works perfectly tho)

    Yes I did a clean installation of the latest drivers 436.30. Used DDU (display driver unninstaller) to clean old drivers, then installed 436.30 using the clean installation option.

    I did check for free NVENC session and there wasno problem there, will try againg later and grab an screenshot to post here

    Ok here are the screencaps of the settings used and the encoder sessions. It never opens a session and there is no other program with an open session itself.

    Again I tested Handbrake and that works ok.

    Below the log of this new test, attached all the screencaps

    I'm having the same issue with a GTX1060. (2.2 and 2.2.2 - NVENC h264)

    NVENC HEVC seems to work though. Do you only have the prob with h.264?

    Actually I didn´t try HVEC, after I saw your post I tried it but nope, it doesnt work

    Make sure there is at least one free NVENC session and close all other programs that make use of NVENC.

    Zitat von Vogelforscher

    The only thing that is not set to default is that your source and export is interlaced. Maybe you could try export a non interlaced source file just to be sure it's not the interlacing.

    EUREKA!!!! Encoding a progressive sequence did work!

    Now I wonder why would be that? I could encode those interlaced projects with the GTX 970 before, just finished such a project one month ago :/

    Found an interesting link...

    https://devtalk.nvidia.com/default/topic/…deo-with-nvenc/

    Proceeded to check myself the available features of the RTX 2060 for NVENC and it seems like nVidia dropped interlaced encoding support on RTX cards :rolleyes:

    Hi Guys,

    Looks like i have now a simmilar problem.

    Using version 4.1 in Premiere on my RTX 2080 Super

    Just made a normal project with adowbe premiere ant tried to convert with nvenc hevc
    But it aborts.

    Please can u help me and what that interlaced encoding means?

    Es sind DV Avi Quellen die ich von Konvertierten V8 Video Bändern bearbeite.

    How can i get it to work?


    Here is my log file and also a picture from media ino with the details of the media file i need to convert.


    Thanks

    and i aprecciate your work!

    Cheers Matt

    Solution:

    1. You could deinterlace (convert it to non-interlaced) it first. Either by premiere oder using a voukoder filter..
    2. You could use the x265 encoder instead
    3. Buy a second cheap older GPU and use it for encoding

    Thanks Vouk for the quick answer. :)

    How does it work with Premiere or with the voukoder filter? (Workflow, how to set it)

    Will i losse any quality through that?

    Sorry for asking, im not yet that experienced with video encoding.

    I appreciate your time and work a lot.

    Cheers Matt
