Super Black
The elegant solution is to use the alphas, just render them to tape, a perfect
traveling matt. It's just the matter of not being able to save the alphas
alone, without the corresponding full color images. I can do it with other
systems I have so I know it can be done. I'd rather do it in a compositing
system but that's more money.
We use the SP because it's a convenient traveling format. It's certain that
not everyone has an Abekas, or can transport files, and going to composite D2
has no advantages over component beta sp. D1 is a little silly, for the expense
thought I've been toying with Abekas 601 file formats since there is some
interesting software that will utilize it. But then I could create the Abekas
files and use something like Diver to convert them to TGAs to be run to tape.
Who knows?
