How do I keep the same colors?

[PHLN]

I used FairUse Wizard to do one episode XviD encode... After I checked and compared it with my DVD source.. The colors seem to be a bit off on the XviD version...

My question is... Is that what happen when you encode XviD? The colors get a bit less crisp? The redish hue turned a bit darker..

My setting was for 350 MB file output for a 44 mins episode...

EDIT -

Here is two screens to show what I mean...

First one... Is the XviD output..

Second one... Is the DVD version...

As you can see.. The quality of the color was reduced alot... Hmm

This is not standard for XviD, color should be as good as seen in the source, you probably have some problems with installed codecs/filters or players.

Try Media Player Classic switching display mode (Overlay mixer, VMR7/9...) and see what happens.

P.S. Or maybe is only a hue/saturation issue...

[PHLN]

Hmm... I tried out the Media Classic thing... Changed the display mode... Don't see any difference...

What is this hue/saturation issue you refer to?

More info... If this help... I use PowerDVD to took both the shots...

UPDATE -

Err... I guess my last bit of info help.. HEHE... PowerDVD has this CLEV-2 mode... I played with it.. Turn it off and on... When off... The color look like the one on the XviD version... When on... It look well.. Like what I thought was the original one...

Interesting... Wondered why that CLEV-2 didn't work for regular .AVI file...

But kool... Thanks for helping me figure it out...

Nice that the problem dissolved as player problem.

Else you'd needed another tool chain for encoding as wrong colours are most likely deriving from colour space conversions in the tool chain.

Didn't want to create the new topic 'cause the problems are quite similar. I've made some experiments with bitrate and found out that the main problem with low bitrate (not too low ;) ) is not the amount of details but saturation. Using the bitrate 1200-1300 instead of black i get dark grey. Ok, I increased bitrate to 2400. Black is fine, but orange became almost red! (I was comparing the pictures in virtualdub with switched off overlay.)
So, is it possible to keep the natural colors from DVD?

Hm...Strange that nobody has noticed same problem...Any ideas?

Edit: Ah! Didn't realize that we were now talking about a different problem. No, I haven't found colors in XviD to be influenced by quantization.

Perhaps 'colormatrix()' would help?

As Koepi said, colorspace problems generally have nothing to do with XviD but with your encoding chain (encoding application, AviSynth-script). Hopefully. ;)
