I need to know which is the best video format for capture a uncompressed frame domestic panasonic DV video cam using the Microsoft DV driver.
I try RGB24
But the quality of the bmp is not great

You can try RGB 24 and YUV. There should not be big differences. What is the problem with the quality?

snap shot is better quality

Thank you for the image. I compared the heads, i magnified them, but i can not see any differences, except the IC Imaging Control image has a little bit more color. But this depends on the used camera parameters only.

Hello Stefan, I don't find the IC control as more color I find the hight light is more bright compare to the other one.
do I get a better quality if i install a s-video frame grabber then the DV signal ?
is there a way to replace the blue background with a still image ?
I like to design a new chromakey photo system

I think, the image properties can be adjusted with the camera properties, like brightness, saturation etc. I can not say, whether you get a bette quality, but S-VHS would be worth a test.
If you want to echange the blue background with a still image, you can use any image processing software like photo shop, paint shop or what ever. IC Imaging Control itselft has no such funcionallity. You may program this on your own, this should not be so hard with a little programming experience.

Hello Stefan, I have an old s-video capture card. I will try to test to see if the quality is better.
For the chromakey what i like to do. is to replace the blue with a still image on a live shot.
I all ready have software to replace the bleu after the shot is taking
Long time ago i use a Targa+ capture card to do the chormakey
