In this example, the Ripple filter is a downstream filter. The Ripple track is nested within the
cube track and affects the entire shape.
Filters and OpenGL Mode
In OpenGL mode, you cannot see non-accelerated objects when you use the on-screen
interactors in the Composite window. When you release the mouse button, the Composite
window displays all objects as follows:
• Filters are applied upstream to take advantage of Avid FX OpenGL acceleration.
OpenGL is a cross-platform standard that dramatically improves the speed and
interactivity of previews.
• Downstream filters (animated or static) slow playback performance. However, any
interaction is accelerated since the filters are not displayed.
• Upstream filters are optimized to provide better performance. If upstream filters do not
animate, playback, and interaction are accelerated. The filters remain visible, even if the
Shape track animates.
• Animated upstream filters slow playback performance. However, they provide
accelerated interaction, even if the Shape track animates.
Saving Effects and Filters to an Avid Editor
After creating and editing the properties of an effect, you can save it to the Avid editor where
they can be rendered. You can also save the effect as a preset. See “Loading and Saving
Effects using the Library Browser” on page 186.
To save the effects settings to an Avid editing application:
• Click the Apply button in the timeline.
