Well,first of all i'am a relative newbie in this cutting and muxing thing.
I encoded a 89 minute dvd svcd compliant using DVDx/CCE@cbr2000/224 audio
I ended up having an 1.4 gig MPV and and 150mb MP2.
Did various multiplexing using BBmpeg, with the following results :
* complete MUX --> mpg filesize 1.96 gig
* MUX start 0 end 60 (e.g 1 min)--> mpg filesize 17.99 mb
* MUX start 0 end 240 (e.g 4 min)--> mpg filesize 83.75 mb.

-first I would expect the complete mux to be the summa of the MPV/Mp2
-second if 1 minute is to result in a 18 mb file, i expect 4 mins to be appx 64 mb and 90 mins appx 1.6 gig.

Seems as the input file size grows, the output file size doesn't grow linear but more exponential.
Is this a normal thing to happen with muxing ?
