you can calculation it by self with video bitrate Calculator :
(Size - (Audio x Length )) / Length = Video bitrate
L = Lenght of the whole movie in seconds
S = Size you like to use in KB (note 700 MB x 1024° = 716 800 KB)
A = Audio bitrate in KB/s (note 224 kbit/s = 224 / 8° = 28 KB/s)
V = Video bitrate in KB/s, to get kbit/s multiply with 8°.
°8 bit = 1 byte.
°1024 = 1 kilo in the computer world.http://www.videohelp.com/calc.htm
