The "-b 640" sets the bit rate at 640 bits per second (not kilobits per second). Here is a revised string that works well: ffmpeg -y -i INPUT -vcodec libx264 -acodec libfaac -ab 128k -ac 2 -b 640k -threads 4 -flags +loop -cmp +chroma -partitions 0 -subq 1 -trellis 0 -refs 1 -coder 0 -me_range 16 -g 300 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -maxrate 10M -bufsize 10M -qcomp 0.6 -qmin 2 -qmax 51 -qdiff 4 -level 30 OUPUT This code didn’t work for me.
