How?????? The ST uses a non NTSC (70 hz) video siginal. If they ARE genlocking, I can't figure out how the trick is down. (The main reason, well okay one of
three or do main reasons) I eventually bought an Amiga was becuase it gave me
an NTSC out to use with my video equiptment.

By the way, a good professional studio should be able to genlock itself to
the NTSC out from yor computer, thus you could use the studio's chroma
key to build the images you want. Using decent studio equiptment has some
real advantages in terms of control and flexability, if you can afford it.
