#Chroma-Key
9 messages in this thread
GreG,
I have no idea of what chroma-keying is, but LIVE does have a feature
where you can overlay your live image onto a genlock screen and pick a color to
make color 0 and thus transparent. Don't know if that helps but thought I'd
mention it.

Stated simply, chroma-keying is electronically "selecting" one color (narrow
range of colors, actually), making that color "transparent", then placing the
resulting image "over" another video signal. For example, a newsman sits
before a large panel painted, say, blue. By chroma-keying, that blue panel
goes "transparent", and news story footage from another source "shows through"
the "window", such that you apparently see the footage over the anchor's
shoulder.
I'm explaining this poorly, I fear — Joanne could do much better — but you
get the idea, perhaps.

Rick,
Thanks for the explantation! Your analagy worked great! When I tell
customers they have a TV-studio in there home, Im not so far of, eh? 🙂

John: Chromakey is a process used in television where an object (person, thing,
etc.) is "video-ed" in front of a special colored screen (usually blue or
black) and that image is electronically merged into another video image. For
instance, you could tape a scene on a London street, tape yourself at home in
front of a chromakey screen, and, thru the magic of television, have a finished
product that looks like you're walking in London. Similar effects can make
people fly like Superman, etc.

Ken,
First off, thanks for the explanation! If I understand you correctly,
If I use Amiga LIVE to tape me doing something in front of a blue screen, that
I could then turn off by setting the blue color to color 0 so Genlock would
come through, then I could run a tape through Genlock and save the resulting
combined image on to another tape. Sounds neat! Im going to have to try it!

Basically thats what it is. I thought that Live might have that capability
since thats how the Mandala system works….almost. But couldn't be sure if
that was done entirely by thier software of Live's. Thanks for the info John.

GreG,
Have you thought about approaching Very Vivid and getting into playing
with their Music Vision Software? I have a demo version that's not flexible at
all, and Im putting the real thing on order soon. Im hoping with their good
pricing structure that this will really catch on. It's an incredible way to
show off the Amiga. A customer brought in an article from a 'Computer
Graphics' magazine where they were talking about this incredible new inverntion
that took 3,000 circuit boards and $3,000,000 to do. It allowed the user to
use his body to point at things on a screen and make a computer do something.
Sounds pretty neat, huh? Also sounds exactly like what I am doing with Music
Vision which cost me $295 for my Amiga. 🙂

John,
I would LOVE to have the complete Mandala system. After seeing Very Vivid
perform I am hooked. But other things have to come first for me….like a
LOTTO jackpot! 🙂 That new invention you talk about really sounds
interesting. And to think….only $3,000,000 to that! GIVE ME A BREAK people!
For the price of an Amiga and Mandala you can do MORE than just point to things
on the screen! John, guess they'll never learn! <grin>
Let me know when you get the complete set-up. Yeah, rub it in! 🙂

GreG,
I'll be sure to let you know. 🙂
