Any chance I could get a little explanation why setting -minrate less
than -maxrate gives a warning saying it "isn't recommended!"?
I realize -minrate is mostly used for setting CBR, but I can't find
anything that really explains why it shouldn't be used for other than
that...ie for setting an actual range... as in MIN - MAX.
In my case it SEEMS to do what I want which is increase the bitrate.
Which I assume means it's retaining more of the original source, since the
resulting bitrate is much closer to the original source. Is it not really
doing that?
Here's an example command:
$ ffmpeg -i video.vob -codec:v mpeg2video -b:v 6000k -bufsize 6000k -minrate
4000k -maxrate 9800k -codec:a copy -copyts -f vob video-MINMAX.vob
The source file has a bitrate of 4685k. Without the -minrate option, the
bitrate goes down to 1852K. WITH the -minrate option it's back up to
4567k.
