As our name says, this site is all about Chroma Key;
"The process of overlaying one video signal over another, the
areas of overlay being defined by a specific range of colour, or chrominance,
on the background signal" (Quantel
Digital Factbook).
Final Cut Pro is hands down the most common chroma keying application
on the mac, and while Shake might be a better tool to do it in, many
more people experience the joys and difficulties of chroma key with
their Final Cut Pro. If there is any additional information missing
from these pages that you think is relevant, please feel free to send
an email to info@chromakey.tv.

The Globecaster has several key features for live virtual
set production; it has multiple configurable inputs to take a variety
of cameras. The Globecaster
has a quality Chroma Keyers, which while
lacking in spill suppresion, works well
with Chromatte which has no spill. A DVE
and DSK (Down Stream Key) are built into the Globecaster, this makes
the Globecaster able to scale the talent into the set and place foreground
objects in front of the talent. Globecaster makes virtual set production
a breeze by allowing you to cut from one composite angle to another
on the fly. The Globecaster also has reflection and refraction capabilities
found nowhere else in a virtual set system.

A Virtual Set uses green screen keying to create a
set or stage that isn't real, and in some cases could not be. Virtual
Sets are ideal for situations where a real set is too expensive because
of either space, location, or materials cost. Building a football
stadium would be very expensive. Building a football stadium made
of gold on the moon would be impossible, but not with a virtual set.
A small stage covered with green screen, Final Cut Pro, and adequate
lighting is all that's needed to put your talent anywhere your imagination
wants to put them. |
