Rendering Effects
583
For example, if several filters are applied to one track, then the filter that appears closest
to the bottom of the timeline is rendered first, followed by the other filters.
See “The Rendering Pipeline” on page 583 for information about the order in which the
elements of an effect are rendered.
The Rendering Pipeline
Avid FX renders the elements of a shape in a particular order, which is referred to as the
“rendering pipeline.” This order is represented in the timeline by the individual tracks in the
timeline, each of which rendered separately. The tracks are rendered starting from the track
at the bottom of the timeline and moving up.
The rendering pipeline makes it possible to have both upstream and downstream filters and
masks. The rendering order is displayed in the following diagram, which uses the cube shape
as an example. The same information applies to any of the shapes:
See “The OpenGL Interactors” on page 52.

Face track Shape Transformation
Filter Mask
Downstream filters and masks are applied
after Transformations and are applied to
the entire shape.
Upstream filters and mask are applied
before transformations and are only
applied to the face of the shape not the
entire shape.
