Average bitrate of video?

[Rapplin]

Hello all, was wondering what the average bitrate of the video that everyone usually gets when converting an .AVI into an svcd compliant MPEG and burned onto 1 - 80 minute cdr. This is using 224 bit for audio and with an approx 45 minute movie file.
The reason i ask is that using tmpeg i usually average about 2100. However, i downloaded a .rar file and then extracted, and then burned the .bin, and eventually it was an svcd of approx the same length (45min) and the quality was very good and the bitrate for the video was about 2500???.....So that leaves me wondering, how can i obtain that quality too, am i doing something wrong?
Any help much appreciated. Thank You

The bitrate dictates the file size. As simple as that. For a 45 min SVCD with 224 audio, the following video bitrates apply (give or take a few bits):

74 min CD - 2000
80 min CD - 2182
90 min CD - 2482

Maybe that figure of 2500 was the maximum rate used? How did you get that figure?

If you use VBR instead of CBR you'll get better quality at lower bitrates.

A bitrate of 2500 will get you around 39mins, 45 secs on an 80 min CD.

Y dun u try fitcd to cal ruffly wat u bitrate u need to burn?

Those numbers are for real, they are better than fitcd.

[Rapplin]

is it very noticeable? (from 2200 to 2500 bitrate?)

[SingSing]

Yes, that the reason high motion movie is better in VBR than CBR.
Those few big scenses normally just squeeze by at VBR high of 2520,
instead of have much of macroblock at CBR of 2200.

Sorry for asking, but when i encode my movie into an SVCD compliant mpeg using TMPEG, where do i go to choose VBR instead of CBR for a high action film?
