I'm currently using Voukoder R2 2.2 and I also tried to reproduce this behavior. In my case I can confirm that, if I choose a bitrate higher than 256 kb/s with stereo sound MediaInfo says it is VBR. When using 5.1 Mediainfo says VBR no matter which bitrate I choose. But I think this is not a Voukoder problem because with ffmpeg commandline this is the same.

					Premiere Pro 2017 uses all nvenc sessions for itself as I remember. So unfortunately you have to use Premiere Pro < 2017 or Premiere Pro > 2017.

					Were in Version 1 some more compiler optimizations active?

					Seems like ffmpeg can only decode bink 1 and bink 2 video files. Encoding is not implemented so far I think. Furthermore a licence is required if you want to implement Bink in your software. But there is an exporter plugin for Adobe to export Bink made by the developers itself. 
- 
					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.

					Please try to copy the .prm file manually to your install location -> Adobe\Common\Plug-ins\7.0\MediaCore 
- 
					Please try again without setting the level flag. 
- 
					In the logfile you can see that the frame rate is set to -4.65. That can't work  If you have used the automatic source detection, set the framerate manually. 
- 
					It would be nice if Voukoder can update itself and you don't have to download copy the .prm file in the plugins folder. Moving the logging view there is a good idea in my eyes. I would like to have something like: Rightclick on the Icon->Export Logfile to textfile.

					I can reproduce that issue with zscale using hevc_qsv and h264_qsv.

					When using 2pass the audio is encoded already in the first pass. When the second pass starts audioRenderer is NULL because it's already done in the first pass I think. With my added if clause that prevents encoding the audio twice, it is fixed. 
- 
					That's strange audioRenderer isn't NULL while debugging, but why it doesn't work? 
- 
					ZitataudioRenderer is suddenly NULL and the Reset() is not called. But i'm not sure how this can happen Yes, in the pull request I have replaced if(audioRenderer) with if(exportInfo.audio.enabled) then everything works fine. I have also made an if clause to avoid that audio is encoded twice when using 2pass.

					I used the same settings you have posted Vouk. Here is a complete logfile. I have also noticed that the Encoder Settings in the metadata of the video are also missing then. 
- 
					I have have used the mkv container. 
- 
					I have fixed it. I will do a pull request later  
- 
					Oh yes, that's an important point!

					Do you have set the level flag in the voukoder export settings? If so, remove it and try again  If this doesn't work please upload the complete voukoder log output in a text file. If this doesn't work please upload the complete voukoder log output in a text file.

					Currently it is not possible to select a pixel format for h264_nvenc. The ffmpeg help output says these are available: If you choose hevc_nvenc it is only possible to select 8 or 10 Bit but no pixel format. These are available for hevc_nvenc:
