TMPGEnc: Changing CQ_VBR makes NO DIFFERENCE TO FILESIZE?

Recently TMPGEnc has suddenly decided to ignore any changes to the CQ_VBR value!!! :evil: The only way I can change the filesize is by raising and lowering the bitrate... I've heard of a bug similar to this in version 2.59, but I have 2.510!! I also tried 2.53, deleting and reinstalling, :( etc... Anyone had this problem before or know how I could fix it???

Why are you using CQ_VBR :?: Go for CQ. It's much better :D
What you are describing means that TMPEG in CQ_VBR mode can't increase the quality any further, so any CQ increase will not increase the file size or quality. This usually happens only in CQ_VBR at a value around 60, depending on the resolution used. So from CQ_VBR=60 to CQ_VBR=100 there's really no signficant change.

Yeah, I think that was the problem.
Thanks! :D

But my source is an avi file and I thought CQ_VBR was supposed to be better for divx....
