Lower values mean better quality.-b:v is the maximum allowed bitrate. Higher means better quality.To convert a part of a video file:ffmpeg -i your_video.mkv -ss 00:00:10.000 -to 00:00:20.000 -c:v libvpx -crf 4 -b:v 1500K -vf scale=640:-1 -an output.webm-ss is the start position in number of seconds, or in hh:mm:ss[.xxx] format. You can get it using your video player (Ctrl-G in MPC-HC).-to is the end position.-vf scale=640:-1 sets the width to 640px.
