To change the video quality here, you have the following options:Īdd the -crf option after -i in.mp4 with a value between 0 and 51, where lower means better quality. If that doesn't work, re-encode: ffmpeg -i in.mp4 -c:v libx264 -c:a aac -strict experimental -b:a 192K out.flv ![]() You might even have a chance to copy the bitstreams, which would mean no quality reduction at all.
