/Thanks in advance

Hi Nin,

I don't know if this helps, but I found this in Virtual Dub's documentation here.

"Which capture format should I choose if I'm going to use video compression?
Ultimately, you will need to choose a format which is compatible with the codec, but if you have a choice, always choose YUY2, UYVY, or YVYU over RGB24. Here's why:

TV cards generally use one of two chips, either the Zoran ZR36120 (FlyVideo-derived devices), or the Brooktree/Conexant BT8x8 series (everyone else). If you look at the datasheets for these chips you will find that they either accept YUV 4:2:2 data from the decoder or produce it internally. Guess how they produce RGB24 data when you ask for it? You guessed it, the YUV 4:2:2 data is upsampled to RGB24. This means that the extra color resolution that RGB24 gives is entirely fabricated.

Choosing YUY2/UYVY/YVYU over RGB24 typically gives you a sizable speed increase, and gives you better compression with Huffyuv.

RGB16 introduces horrible banding and signal loss, while RGB32 just adds an extra 8-bits of junk to RGB24. There is no point in using either."

Hope that helps.
