bitrate calculator for divx5 pro

[Thermomonkey]

I've encoded a dvd to divx5 pro using Gordain Knot (using the divx5 guide). The quality was excellent, and it worked fine. However, the file size was considerably smaller than expected (what Gknot worked out.) I have read that divx5 pro files are smaller than divx4.11 files, so is there a calculator about, or an update to Gknot to determin the bitrate needed for a divx5 pro file?

Thankyou

(I appologise for my lack of knowledge, i'm new to this)

Hmmm:

I've encoded 2 films using divx pro. one was 'gladiator' in which the bitrate was correctly (or near enough) calculated by Gknot. The other was x-men, which i specified that i wanted it to cover 2, 700 meg cd's (inc audio.) The final file size is 899 meg. Can anyone shed any light on this?

btw, I used 2 pass mode in vdub for video encoding.

I know that X-men compress very good and can fit 1 cd easy with good quality.It seems that you have reach the max of filesize.But you can go for a higher resolution or AC3 to get a bigger size.

I had the same problem with "The mummy" I only got the video size to ~1.01 Gb when I wanted it to be 1,2Gb. Have you selected sharp biocubic. Or try to select a bigger resolution that helped for me at least

I'm working on a DivX 5 Bitrate Calculator. For the moment, it's the beginning : it work very well with 1 CD Rips, but due to DivX5, the 2CDs bitrate calculation is less sure... look at www.lovecraft25.fr.st

cool, thanks!

Yep. I just encoded this movie. Super compressible. At 640 by whatever, I was at 68% quality according to GKnot. Used Ogg Vorbis -quality 2 audio. Lastly, resize method was changed to LanczosResize.
