To encode XAVC I using ffmpeg, you need to have the following command line
ffmpeg.exe -i input -c:v libx264 -avcintra-class 480 -pix_fmt yuv422p10le -preset ultrafast -x264opts avcintra-flavor=sony -c:a pcm_s24le -ar 48k output.mxf

Hi,
I am using Vegas pro 17 with the latest voukoder 4.1 and connector 0.7.0.
I compared the output between Voukoder and nvencc64 right out of Vegas with the same video, resolution 2704x1520 - 30p
Exactely the same parameters: CQP 23, Preset medium, Advanced option exactly the same as well.
Voukoder is giving a video srtream bitrate of 2160kb/s.
Nvencc is giving a video stream bitrate of 70.9Mb/s.
Bitrate from Mediainfo.
Obviously, Voukoder output is of a very low quality, Nvencc one very close to the original.
Why so much difference using the same CQP?
