Advanced Composition Settings

Advanced Composition Settings

In addition to the Motion Blur settings introduced in
Chapter 2 and detailed in Chapter 8, Composition Settings:
Advanced contains two Preserve toggles that
infl uence how time and space are handled when the composition
is nested into another.
Preserve Frame Rate maintains the frame rate of the composition
wherever it goes—into another composition with a different
frame rate or into the Render Queue with different
frame rate settings. So if a simple animation cycle looks right
at 4 frames per second (fps), it won’t be expanded across
the higher frame rate but will preserve the look of 4 fps.
Preserve Resolution When Nested controls what is called
concatenation. Typically, if an element is scaled down in a
precomp and the entire composition is nested into another
comp and scaled up, the two operations are treated as one,
so that no data loss occurs via quantization. This is concatenation,
and it’s usually a good thing. If the data in the
subcomp is to appear pixilated, as if it were scaled up from
a lower-resolution element, this toggle preserves the big
pixel look.

Adjustment and Guide Layers

Two special types of layers that don’t render, adjustment
and guide layers, offer extra benefi ts that might not be
immediately apparent.
