Super Black, if I am not mistaken, is simply RGB 000. "Black" that is going to be broadcast as is should be 7.5% Gray. That is the "Black" that editors set their waveforms to. Super black is also called "key black" because it is used when straight chrominance keying is to be attempted (without the aid of alpha mattes). If mattes exist, of course, it doesn't matter what the background is (except for mixing solid key backgrounds with non-solid source backgrounds or vice-versa). As digital matting techniques get more sophisticated, the key-black thing will become less important. Ken Loss-Cutler
