[FFmpeg-user] Command line -b:v 20M Bitrate spikes to 65000

[bdkneela at yahoo.com]

I want to try that, however i cannot seem to find a good reference as to what values to use for -bufsize. Also if i use maxrate and bufsize, do i still need -b:v ?  As you can tell i am a little out of my depth here with command line. 

Any suggestions?
