Product Overview
Shake 4
Rotoscoping and Paint
Rotoscoping
In Shake 4, you can mask a layer or an e∂ ect to control which areas of an image are
modifi ed (like a bright color correction on a portion of the image). For sophisticated
animations, each mask in Shake 4 can be keyframed, or each point on the rotoshape
can be tracked, and a photorealistic motion blur can be applied. Multiple shapes
can be created within one rotoshape node, while soft-edge fallo∂ controls can be
modifi ed independently on each control point.
Paint
The Shake 4 QuickPaint node is a touchup tool that can fi x problematic shots such as
holes in mattes, or scratches and dirt on your images. It is a procedural paint system
that allows you to change strokes after they have been placed. With QuickPaint, you
can apply the e∂ ect and easily ignore it, remove it, or reorder it after you have applied
your paint strokes.
Because QuickPaint is a vector-based procedural paint system, you can modify the cur-
rent stroke or any previous paint stroke. You can also modify the paint characteristics
(color, size, brush type, opacity, softness) or the position or shape of the stroke.
32-Bit Keylight and Primatte
Keying usually involves the extraction of a mask from a fi gure shot in front of a blue or
green screen. This image can then be composited on top of a di∂ erent background by
removing the blue or green.
Shake 4 includes two industry-standard keyers, Primatte and Keylight, that operate
with full 32-bit fl oat precision to ensure the continuation of high bit depth through-
out a project. Whereas other packages take a “one-keyer-does-all” approach to keying,
Shake 4 allows you to combine keys to achieve the best results.
Shake 4 also includes tools for pulling keys based on luminance (brightness) and
depth calculated by a 3D render.
