This simple script:
AVISource("source.avi")
ConvertToYUY2()
when used with NTSC DV and VirtualDub appears to make the darks darker and whites whiter and larger. I'm working with a camcorder source where no filters were used and blue and green stage lights were hitting the camera.
Darks getting darker doesn't bother me too much but I would prefer that to be something I control.
The real problem is the overly saturated white areas are becoming enlarged. Faces, hands, dark details on otherwise white objects are all becoming less distinct. They're horrible in the original because they're white blobs with dark spots where eyes should be, etc. After conversion, those dark areas are smaller or non-existant.
Is there a technique for converting the colorspace which will help prevent this?
