Apple Shake 4 - Manual (Page 991)

Chapter 32 The Cookbook 991
This example has a slightly high saturation, a slight blue cast, and punchier whites (but
then again, 30 seconds were spent on it). Note because the tree is made of three
concatenating color corrections, it was not necessary to convert up to float bit depth
before the LogLin.
Deflicker Macro
This macro is helpful for reducing the flicker on an image. The macro takes two
inputs: The first input is your reference frame, which should be a single frame from the
clip you want to affect; the second input is the sequence you want to remove flickering
from (a bluescreen image in this example). To use the macro, place the crop box on an
area that is representative of an area that does not change its content, that is, over a
portion of sky, rather than on the moving traffic below.
The first frame is usually a still reference frame. The second input is the flickering
sequence. Position the box while looking at Input1 (SingleFrame in this example).
