CQMatic and Divx? Or should I use ToK?
 
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. :D

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

muhali3 10-18-2003 12:56 PM

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 ?

muhali3 10-18-2003 01:31 PM

i'm sure i did, but i'll try it again.

Dialhot 10-18-2003 02:06 PM

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 ;-)

Yeah it works now. thanks dialhot

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

what are you guys setting as max/min bitrate in tmpgenc when using cqmatic with divx/xvid files?

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)

J-Wo 11-28-2003 09:55 PM

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 :D
I think the 0.57*average is not really needed if you use X3 mode with CQMatic.
