[FFmpeg-user] problem with limitng output bitrate and VBV underflow warning

2017-04-09 Thread negin tebyani
I am using this commad to transcode a video with 12000k bitrate to a lower bitrate like 300k. here is my command: ffmpeg -i 12000.mp4 -movflags faststart -c:v libx264 -x264opts 'keyint=288:min-keyint=24:8x8dct:sliced-threads=0' -deblock 1:1 -flags +loop -b:v 300k -maxrate 300k -bufsize 1000k
