Chroma Key Studio is one of 28 new filters in Boris Continuum
Complete 6 FxPlug for Apple Final Cut Pro, Motion and Final Cut Express
and a fresh addition to the Boris Continuum Chroma Key Unit. Chroma Key
Studio builds on the strength of previous BCC keying and compositing
tools with features such as a best-of-breed chroma key process, spill
suppression, matte choker, and a light wrap compositing step. All four
tools are combined in one, easy-to-use filter; there is no need to
stack multiple filters to pre and post process video. What’s even
better is that all four steps are now implemented in OpenGL for blazing
real-time previews and rendering. All necessary keying and compositing
steps are executed flawlessly on your graphics card. Let's dive in and
see how it's done...
In
Final Cut, place a green screen clip in the timeline and apply the BCS
Chroma Key Studio filter from BCS Keying category. BCS stands for Boris
Continuum Shaders, signifying that all BCS filters are implemented
using "shaders" - special code for programmable GPUs.
The
first step in using Chromakey Studio is picking the backing color with
the eye drop tool. Zooming in on the backing area of the green screen
clip we can see that there is a fair amount of noise in the green color
but the keyer will have no problem with that. There is no need to
pre-process the clip to reduce or remove the uneven luminance. In fact
such noise is normal and the keyer is already designed to deal with it. read more...
