Default bitrate calc for gnkot.26?

I use the 2CD rip function in Gknot with the original 720 X 480 resolution and the sharp bicubic option. Also i have been picking 128 Kbit for my mp3. However my movie is never big enough. Always 1.30G or 1.32G, never fills up 2CD's completely. Is there a bitrate calculator for Gknot that i can use so i can fill my cd's up?

Are you doing a 1 pass or 2 pass encode? If you are doing 2 pass then gnot automatically calculates the bitrate for you.

This most probably happens because the maximum quality has been reached or you are very close to max quality. This can easily happen when you encode with b-frames enabled.

So unless your video has some obvious quality problems, don't worry about this.

Well i always use 2 pass encoding with divx5.02 pro. What i don't understand is when i change Gknot from "calculate average bitrate "to calculate avi file size" (where i can manually choose the bitrate) it does not matter how much i increase the bitrate, my file size stays the same. THis is not logical. With any other encoding program when you increase the bitrate you increase the file size (and quality). With Gnot this is apparently not the case.

Are you honestly telling me there is no way to fill up two CD's from a DVD without increasing my audio in a huge waY? What about when i rip the CD in SmartRipper, should i increase rip size from 4000MB to 5000MB?

Gee I never thought small files would be a problem!

It is completly logical, maximum quality has been reached, and the codec won't just fill up the unneeded space with zeros.

Increasing the encoding resolution would also increase the maximum possible filesize.

What do you mean ?, you should be ripping in movie mode. Smart ripper has no effect on the video quality of the rip. It just copies the mpeg-2 encoded data. I suppose you could grab some extras and put them on the DVD.

It's only a problem if you think it's a problem
