What is the formula for outputfilsize in BBMpeg???
If you have a 700 Mb M1v file and multiplex witha a 100 Mb .mp2 file, will the filesize of output .mpg file be less, equal or greater than 800 mb?

Hay Jore, exuse me for jumping in here.. but..

Assuming my math is correct:

(700+100)*0.5 = 400 ??

Or, is it 40mb ??

Or, is it 4mb ??

I see only one decimal, so do I move one dec. to the left, and it now
becomes 40mb ??

2nd question:
And, 0.5 % .. is that accurte enough ??

and i "re jump" here again my friend vhelp.

~0,5% (middle of 1%) means "more or less" 4mb.

800*0,5% 4

accurate enough?
after mux, i ever got this proportional results!
