In VirtualDub's capture mode, the histogram shows luma of the captured video; is it possible to adjust brightness and contrast levels to "stay inside the borders"...
what I'd like to know is: the red part of the histograms at left (luma black point) and right (luma white point) must never appear to obtain a good luma range (16-235), or they are just "red alert" - I mean, the histogram could reach those red parts but only for few moments - like the red part of analog audio meter?
