I use DVD2AVI YUV, DKnot(avisynth), DivX4
The 1st problem:
After I encode and i playback the movie , i need to increase the brightness of the divX filter (to 56) in order to get the same image quality as the original picture.
This happens with all the players that directly use the filter.(Dont get confused... i mean ALL of them: Mediaplayer, microDVD , powerDIVX... etc)
What the ... is going on? Can't the codec keep the original brightness? (i compare the original colors using DVD2AVI(i check the RGB option because the YUV one is darker BUT for the d2v project i use the YUV option) and PowerDVD where i load the vobs)

The 2nd problem:
When i encode anime(at least till now!) the colors get screwed up. I try to improve the quality using brightness(yes i have problem again) and saturation but i can't reproduce the original quality. The colors seem pale... . BUT when i load the avi with VirtualDub everything looks great. Colors and brightness are all perfect!!
Why??? Am i doing something wrong? Is there a bug with the codec?

The question:
If i use VirtualDub, load the DivX4 filter and change the min,max quantizers (or something...), then close vdub so as the settings are saved, will Gknot use these settings instead of the default 2,12?
Does Gknot always "reset" to the default 2,12? Is there a way into forcing it to use others?

Ooof.... thats about, it thanks!

Not sure about your anime question. However, I also have my DivX brightness slider cranked up about 2-5 notches higher than the default setting. The movies do sem to go darker somewhat than the original VOBs but I always assumed that was the nature of the beast (DivX).

Yep-I agree with matter-I keep my setting at 54.

Scout-I also have noticed the anime colors being washed out a bit. I'm not sure, but I think it's the default IVTC in GKnot that does it. Anyway, I use the Hue, Saturate, Intensity filter with Saturate at 1.30, and it fixes it up.

Thanks guys!

At least i'm not alone!
Try opening your divXs with vdub to see if the colours are ok!
I also did some rips with vdub (vfapi) and the color problem is the same... i smell a DivX codec BUG here!

Anybody with a reply to my question? (The WEF?)
