when i use frame selction, do i have to enter the uncutted filmlenght into the bitrate tab od the cutted? is dvd2svcd recalculating the bitrate if i cut a movie from abou 65min to 55 min od do i have to enter the cutted filmlenght in oder to get an "fullsized" disc?
thanks

As per the Q+A:
Q36: Could you please explain how dvd2svcd uses the bitrate tab in details?
A: What dvd2svcd do to calculate the avg. bitrate:
1. DVD2SVCD starts CCE and load the avs file and save the project file (ecl) and closes CCE again.
2. DVD2SVCD opens the project file, and it finds the number of frames and the framerate in that project file.
3. Using the frames and the framerate dvd2svcd calculates the number of minutes the movie is.
4. Using the minutes, dvd2svcd goes through each line in the bitrate tab. When it finds the line where the minutes are between X and XX minutes dvd2svcd get's the number of cd's and the cd size it should use.
5. DVD2SVCD then uses minutes, number of cds and the cd size to calculate the highest bitrate to fill the number of cd's to the limit.
6. DVD2SVCD calculates the avg. bitrate, modifies the Project file, runs CCE loads the Project file into CCE and starts encoding.
I doubt this part has changed. So if it hasn't then the bitrate is not actually determined until the begining of the encode and thus you do not have to worry about doing any calculations yourself other then within reason to figure out gow many discs you want it on etc...
Now this was written before TMPG support so I do not know how TMPG is used exactly.
