vokouder r2.0 beta3 - GPU at 20% ( beta2 95/98%)

  • Hello,


    i don't know if this is a bug or because this version is free but Vokouder r2 beta3 is extremely slow compared to previous beta1 and beta2.


    previous version can export a 6 minute video timeline with grading and PP in under 1.30 minutes.


    settings used in both Vokouder r2 b2 and b3


    with vokouder r2.0 beta3 the same video with the exact same settings require about 8 minute to export and the gpu utilization is 20% compared to 95/98% from the beta2.

  • Voukoder ignored the "Render with maximum bit depth" option before beta3. If activated now it uses a very expensive render path. If you uncheck it you should have the old speed again.

    Please open voukoder again and copy the logfile to this forum.

  • I just checked the premiere sdk documentation.


    It was wrong to use the "Use max. render quality" option for that. I will revert that change.


    Instead I will activate the outUseMaximumRenderPrecision setting.

    Thank you Mr Vouk,

    i'm not a developer but think that the critical aspect of developing a program is the possibility to find strange errors and i'm really happy to have discovered this for you :).

  • I have tested the speed differences between Voukoder 1.2.0 and Voukoder R2 (beta3 and beta4). And I can say that Voukoder R2 is very slow compared to Voukoder 1.2.0 with nvenc. I exported a 50 min video with the same nvenc settings in Voukoder 1.2.0 and Voukoder R2. In version 1.2.0 it takes about 5 minutes, in Voukoder R2 (beta3 and beta4) it takes about 9 minutes. I attached two screenshots from the taskmanager which shows that version 1.2.0 uses more Video engine power I think.

  • 1.2.0 settings = h264_nvenc with options: b=2000000,bf=2,maxrate=3000000,preset=slow,profile=high,rc=vbr,refs=3

    R2 settings = vcodec: h264_nvenc, voptions: _computeCapability=6.1,_pixelFormat=yuv420p,b=2000000,gpu=0,maxrate=3000000,preset=slow,profile=high,rc=vbr, acodec: libfdk_aac, aoptions: _sampleFormat=s16,profile=aac_low,vbr=3, format: mp4, faststart: 0

    And I noticed that Voukoder R2 log is flooded with this:

    Code
    1. Calling dl_fn->cuda_dl->cuCtxPopCurrent(&dummy)
    2.                                        
    3.  [2019-04-12T17:31:22] Calling dl_fn->cuda_dl->cuCtxPushCurrent(ctx->cu_context)
  • I compared the two files from version 1.2.0 and r2 and I can say that the quality of version r2 is a little bit better in rainy scenes than 1.2.0 but really hard to see . So there has to be some difference in the settings but for this loss of speed?

    There is also a wrong default value in voukoder r2 with nvenc h264 I noticed. In the GUI ref frames have a default value of 3 but the exported video has 1 ref frame.

  • I just compared the encoding speed of version 1 and 2. And it is pretty much identical.


    Maybe you are comparing a release build and a debug build? Debug is always slower because performance optimizations are disabled there.

  • Both are release builds downloaded from github releases.

    Some strange think is also why R2 is using less video engine power but more video copy.

    You are using a RTX card right Vouk ? Maybe its only affecting Gtx cards because of a new nvenc version or something?

  • It might have to to with libav logging a bit. When I disable the logging and have my own logging instead it looks like this:


    pasted-from-clipboard.png


    My logging looks like this:



    The fps are actually misleading. It were "only" like 430 fps actually.


    Code
    1. # GPU Session Process Codec H V Average Average
    2. # Idx Id Id Type Res Res FPS Latency(us)

  • The R2 logfile looks also pretty strange. I think the log is not complete and missing entries.

    Here is are my fps values with 1.2.0 and R2 beta4. Hugh difference. And I attached the R2 log.

    I am pretty sure that I am using the same video export settings but also by changing some parameters, R2 is every time much slower.

  • Hi All,


    Hi Mr. Vouk,


    i've tested the new r2 b4 and i'm soo sorry for the following


    the plugin seems to extremely slow "even wothout high quality checked". Seems to have capped at 20% and seems that ignores every settings combinations :(.


    In task manager i see about 20% of Hardware encode utillizatin. the export works well but the benefit of GPU hardware accelerations completely disappear.


    i have the latest premiere pro "adobe cloud subscription" and a 2080 ti with 425.31 "gaming" drivers.


    Hope i'm wrong but i think that Nvidia is the responsable for this...


    if i can help you . please tell me how.

    ( the export was cancelled by me :) ).
