Hi all

I want to know, how big will a 1 minute video will be if the bitrate is 10500kbps (and assume that the audio is 64kbps)?

Thanks all!

Solution
This is not homework, is it?

(1050000 + 64000) * 60 / 8 plus some additional bytes of framing depending on the codec and transport container.

you can calculation it by self with video bitrate Calculator :
formula :
(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.
