The best video resolution (image size) compared to bitrate?

[Thomas-MacFreak]

In this guide: http://www.divx-digest.com/articles/dvd2divx5_gordianknot.html They write about how to get the best resolution compared to bitrate. How is this actually calculated?

Is it like this?

Example:
Videobitrate: 1035 kbit/s
Aspect ratio: 576x304
FPS: 25 (PAL)

(1035 x 1024) / (576 x 304 x 25) = 0,24

This should give us a good image quality, according to the dvd2divx5 guide at divx-digest.com, because it is between 0,17 and 0,30

Example:
Videobitrate: 1035 kbit/s
Aspect ratio: 576x304
FPS: 25 (PAL)

(1035 x 1024) / (576 x 304 x 25) = 0.24

That sounds about right to me - the only thing I would suggest is that some programs say 1 kilobit = 1000 bits, but that shouldn't alter the ratio all that much.

Perhaps enquire in their forums also ?
