If not, the MIDI trick you were talking about might be an interesting avenue to explore. The other board is at http://www.fxplugfx.com/forum/index.php They just recently opened up a developer section and they referred me to this list.

Admittedly, it's not an FXPlug application. Does anyone have a good idea how they might be doing this? Mike, FxPlugs can get some timing information starting with FCP 6 and Motion 3, but it's not clear what you mean when you say you want time code data. Can you describe in more detail what you're trying to accomplish? It may be possible to do what you want. Looking at DigitalHeaven's website for BigTime (<http://www.digital- heaven.co.uk/bigtime/>), it appears that it's probably making itself available as a MIDI device, and rather than sending the data out to some actual MIDI hardware, it's displaying the information. That's just speculation on my part, though. It's an interesting idea! I believe that FCP 6 also has some AppleScript capabilities. I haven't worked with them, but it may be possible to get some information out of FCP via that route, too. But if you're just trying to learn FxPlug, definitely have a look through the FxPlug sample code, and feel free to ask questions about what you're specifically trying to do or learn.

It's a strange choice, but that's the way it is. I've never seen a formula for premultiplying YUV. Is it just a linear scaling of the Y channel by the A channel?
