Hello, i am trying to encode with a variable bitrate, 2 pass encoding, using the codec hevc_nvenv.
ffmpeg -i infile.mkv -vcodec hevc_nvenc -preset slow -qmin 1 -qmax 50 -b:v 4000k -c:a copy -f matroska outfile.mkv Theorically it shoulds use 2 pass encode, and it encodes with half speed respect to preset medium. My doubt is that ffmpeg do not iterate the encoding two times creating a logfile. ##SELECTION_END## If i use the option -pass 1, it creates a empty logfile. How 2 pass encoding of nvenc works ? Someone know the exact or the best command syntax in order to do it ? Sorry for the bad english. Thanks for your attention. -- Marco Diletti <m.dile...@yahoo.com> _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
