    Accelerated h264 encoder leads to LOW bitrate output (ignoring settings)

    curiouscat951 Level 1

      I have a i5-6600k with GTX 1060, with internal GPU simultaneously enabled for accelerated h264 encoding.

       

      While it is super fast, the behavior is erratic.

       

      For instance, my settings are 4K, 24fps, HIGH Profile @ 6.0, CBR 150MBPS and eventually the output becomes VBR 3.6MBPS at the same resolution (checked with MediaInfo and it's clearly crap visually).

       

      This happens 90% of the time, while at other times it doesn't obey my settings but goes slightly below 150MBPS, which is fine to me.

       

      Any advice on how to rectify the issue?
