Other min & max quant settings in GKnot

[stargazer]

2/12 are default quant settings (using GKnot+Divx 5.0.2)- is there any way to change it directly in GKnot, or I must do it manual in VirtualDub?

BTW, when compressing very compressible sources (movies like Matrix) is 1/10 quant range (or some other) better solution and is it even possible to set min quant to 1 or below 1 (decimal values)?

Sorry for my bad english :)

why are you trying to set those? it's not like using flask or xmpeg or something.

with two pass, those settings are useless... or so i thought.

I don't know much about quantizers but IMHO, they are directly responsible to frame encoding quality (which is linked to size). In 2 pass encoding, 1st pass is used to get info on every frame, including quant. If you set min quant 5, even the most demanding scenes will be encoded at quant 5, so the quality will be low.

I'm interested is quant 1 possible and does it mean a better quality (will it affect other, less demanding scenes, to be encoded in lower quality so the final result will be worse then the 2/12 combination)

...if anyone understands this, I don't ;)

Hi-

Yes, DivX5 has a Quant 1, but as I understand it, 2 pass encoding, whether through GKnot or directly in VDub won't use it. But since a Quant 1 frame is something like 3 times the size of a Quant 2 frame, it's not very useful when file size is a consideration. As far as I know, the only way to actually use a Quant 1 is to do a 1 pass quality based encode. Please see this Thread (http://forum.doom9.org/showthread.php?s=&threadid=31206&highlight=quant) for more information.

Thanks, manono!

This thread is the same one that I could not find :)

There are all answers to my questions... I'll continue to use 2/12 combination...
