Super Black
Hi!
Realy, the way to go is to use those alpha channels… We've had to go through
all this for some projects. If we want to output something to be keyed, then we
use
Yost's Clamp IXP to restrict the range of the luminance in VPost, using a
matte.
But this not realy an ideal solution.
Sometimes we bypass this process by fiddlin' with the ambient light level
(start with 60) to restrain our blacks.
Since we always render to disk (we use an Abekas A65), we enforce matte
generation for all our projects. 8-bit files are not that big…<g>
Let us know if you find an elegant solution!
