Doom9's Forum - View Single Post - DiAVC decoder, yet another fast H.264 high profile decoder

I would be thankful for a hint,
can't seem to find a working registry entry for DiAVC's frameserver settings.
(WinXP32 SP3)

Right now I got some poor and underexposed 1280x720x25p on 50p AVCHD cam footage to edit.

If I preview in MPC using DiAVC and DiAVC "Properties" Window:

A: Crushed shadows if I leave levels set to "Auto".

B: Still underexposed, but shadows are not crushed too much anymore
when I manually set Levels as follows: Input PC Range, Output TV Range.

Now I'd like to do frameserving using DGAVCDecDI and I would like to use the same preset, but how ?

The frameserved result unfortunately gets crushed blacks.
The histogram borders come out close to a rectangle with a strong peak at Y=0.
The DGAVCDecDI chain seems to assume "Input/Output Level: Auto/Auto"
so obviously does not read from the GUI settings.

A decoding workaround:
Sony Vegas Pro 10 still decodes this stream with a 0-255 histogram with a slight peak at Y=0 or 1,
and not too much crushed shadows, so I decode in Vegas for now.
