cce math question

[Forko]

i just finished encoding AI. in cce it said my file size was going to be about 3,187,351,283. my audio was about 699,287,365 (these are estimates for what the file sizes were its just an example). my movie came out to be 4.11gig. what equation could i have done to get it to 4.37?. i tried adding the 2 numbers then multipling by .05 but did not have any luck. thanks for the help!

also if youd do just one pass how do you calculate the bitrite so it becomes 4.37 also. thanks again

this is the way i do it ... open vobs in rempeg from a vob list ( look at the rempeg guid on how to make the list ) ... your not encodeing here .. but rempeg does give alot of information about the vobs once you load them.
Get the dvd-rcalc program off the downloads page here ...
use the numbers in rempeg in the dvd-r calc .. the orginal vob size is what it gives you when you highlight all the vobs and right click / properties .. NOT "size on disk" the other number.
on the bottom of dvd-r calc it will give a % that you have to decrese the video size in order to fit a dvd-r ...
goto options in rempeg and slider the slider to that % ( i.e. 82% ) .. under the slider their will be a number .. THATS the average bitrate to use in cce.

you can change this a SMALL amount if you are useing the cce guide here and doing 2 single vbr passes .. but it should give you an idea of where you want to be.

Im not sure exactly how your doing this, but here is what i do... I use RE-Empeg.... should be the same for whatever proram you use.

I take a few variables:

A: Size of OriginalVobsTogether
B: Size of OriginalVideoOnly
C: Size of OriginalSoundOnly == (a-b)
D: Size of 4.3DVD-R
E: Size of NewVideo
F: AverageBitrate of OriginalVideo.
G: AverageBitrate of NewVideo

Then enter them in the equation leaving out which ever variable u need.

{f/[a-(a-b)]}={g/[4.3-(a-b)]}

hope that helps, not sure really what the question was, im thinking that was it?
