 .IP "--hard-cbr"

 Use hard constant bitrate encoding

 .IP "--comp N"

-Encoding computational complexity (0-10, default: 10)

+Encoding computational complexity (0-10, default: 10). Zero gives the

+fastest encodes but lower quality, while 10 gives the highest quality

+but slower encoding.

 .IP "--framesize N"

 Maximum frame size in milliseconds (2.5, 5, 10, 20, 40, 60, default: 20)
