Number of reference frames

  • If, using NVENC, use or change the parameter "Number of reference frames", Voucoder crashes. The log contains the following:

    The same thing happens if you turn on "Weighted Prediction"

  • Can you test this with ffmpeg.exe on the command line? OR run premiere from within windbg.exe and check the low level log file there?


    I am not 100% sure but maybe your GPU does not support these options.
