Sure, I'd like to see it. I'm seeing this artifact more in my VideoCDs than in my DVDs. It almost looks like the quantization floor is set really high for MPEG-1 video or something. The non-dark scenes all look really good. What about using an edge-detection algorithm to find the boundaries of large areas, then testing if the large area is low-intensity before setting it all to black? I haven't looked into edge-detection algorithms recently, but it sounds good... Steven Boswell ulatekh at yahoo dot com __________________________________ Do you Yahoo!?
