What's the deal with Adobe Ultra?

Sorry about all the weird symbols.  Apparently if one goes to edit one's post, all sorts of weird symbols get inserted.

But what does one use to make the best, cleanest keys, if one cannot get Ultra?

Thank you.

There are other options (although I am told Adobe is bringing back a form of Ultra in future product(s) but that reamins to be see as to what and when).

Boris has some help - from their web page (http://www.borisfx.com/tutorials/chroma_key.php): "BCC Chroma Key filter included as a standard feature with BORIS RED. However, the same BCC Chroma Key is available in the lower-priced BORIS FX package. Both
RED and FX plug into a wide range of NLE systems from Avid, Apple,
Adobe, Sony (Vegas), Harris (DPS Velocity), Canopus (Edius), Media 100,
and others. In addition, BCC Chroma Key is part of the BORIS Continuum
Complete filter set available as native plug-ins Adobe, Apple, Avid,
and other NLEs."

Adobe never actually integrated Ultra into the Production premium product line, that was the problem. THey used to just give it away with the suite but it was never intended to work with the other applications. So for the CS4 release since they wanted to put an emphasis on other areas of the programs. The rumor is that it will be integrated into later versions of the package. It isn't really an emphasised piece of software for the suite since keying iwould usually be handled by the tools in After Effects.
