it seems, that the quality slider in the video tab doesn't work correctly for x264 encoder. When I try to use it, I got crazy numbers. I got also minus values when I olayed around with the fraction settings in options-advanced panel. Does anybody else has the same problem? currently I must use the command line to set the quality to RF19.
