A Half M/E that provides additional mix and cut functions is also included
with this option. Half M/E and DSK functionality cannot be used simulta-
neously, however.
Flexible Chroma Keyers
Additional Dual Chromatte flexible chroma keyers are also available as an
option. Two chroma keyers are included with each option. Each chroma
keyer can be flexibly assigned to any desired keyer in any M/E.
3-D Digital Effects Concepts
The Kayak Digital Picture Manipulator options provide 3-D planar image
translation and transformation from within each M/E of the Kayak system.
Image translation has special basic concepts and terminology you should
understand in order to get the most out of using the option.
Translation and Transformation
Translation is a subset of transformation, and involves picture movement
along the X, Y, and Z axis. The picture is simply relocated to a different
place and does not change in actual size or shape.
Figure 33. Picture Translation
Transformation includes translation, and also includes these other func-
tions:
Size
Enlargement and reduction of the picture area while it remains in the same
plane in 3-D space. This is different from picture translation in the Z axis,
where the picture retains its original size, but appears smaller when moved
away, and larger when moved closer.
