Sorry guys I've been gona awhile. Can CQMatic accuratly predict and convert avi files to KVCD or should I use ToK? This is the first time I'm doing a avi to KVCD instead of dvd to kvcd that i'm used to

Thanks

when i use cqmatic, it always gives me a cq of 89.77 on avi files. So i use ToK, or use manual prediction.

but cqmatic might work for you, just test them out.

That means that you do not know how to use it. Why didn't you ever ask for help ?

i have asked for help but it still doesn't work. how long does CQMatic usually take? because when i use it, it takes like 2 seconds and then it says final cq is 89.77

5 to 10 minutes per try. So that clear that it doesn't do anythign on your PC.

First, did you set the path to TMPGENC in CQMatic settings ?

After you try, post here the log of CQMatic.

Note: I have reinstalled CQMatic tghis afternoon and forgot to give the path to tmpgenc. The result was exactly the one you have. And that's normal indeed

@audi2honda: I guess you should use CQmatic, it gives a very accurate CQ

The min is tied to the standalone, so your question isn't very relevant. But my settings are 64min - 2300 max (I lower it down to 1800 for long movies)

dialhot, what do you mean by "The min is tied to the standalone"? Right now I have 300min, 2500max. Why do you use 64? Does anyone use 0.57*average anymore?

Dialhot means that some standalone players don't like a bitrate below a point. The reason I selected 300Kbps, is because most players tolerate that value as a minimum value. But if your player can go lower ( some can go down to zero ) then do it
That will save some bits, which can then be used in the high end (MAX) for high action scenes.

He uses 64 because his player can do it
I think the 0.57*average is not really needed if you use X3 mode with CQMatic.
