Hello,
I have a problem.
I am currently working on an Episode IV restoration project and I was "recoloring" the whole Tantive 4 sequence. After I've achieved that 3PO is gold, stormtroopers are grey and the walls are white, I have exported it (from VirtualDubMod) as uncompressed AVI file.
Then I did put this AVI into good old CCE and created an mpg2 file. The problem is that while the AVI file looks exactly as planned, the resulting mpg has completely different colors (for example the walls are light grey) and is much darker.
I think the problem is that the AVI is RGB24 and the mpg is YV12, but I have absolutely no idea what to do with it

In the advanced video settings in CCE, change the luminance level from 16-235 to 0-255.

That was the first idea, and it didn't work

The problem is that CCE doesn't want RGB input, it wants YUY2. It sounds like whatever's doing the colourspace conversion is getting the luminance levels incorrect.

Instead of saving out uncompressed RGB, save as uncompressed (or losslessly compressed) YUY2.

Yes, it's worth trying. Thanks
