ADOBE AFTER EFFECTS 5.0
User Guide
Frame blending slows previewing and rendering. To speed things up, you can apply frame
blending without using it to redraw or render. The Quality setting you select also affects
frame blending. When the layer is set to Best quality, frame blending results in smoother
motion but may take longer to render than when set to Draft quality. You can also enable
frame blending for all compositions when you render a movie. For more information, see
“Changing render settings” on page 358.
To apply frame blending to a layer:
Select the layer in the Timeline window and choose Layer > Switches > Frame Blending.
A check mark by the Frame Blending command indicates that it is applied to the selected
layer. Also, the Frame Blending switch ( ) appears in the Timeline window Switches
panel for the layer. Remove frame blending either by clicking the Frame Blending switch
or by choosing the Frame Blending command again.
To enable or disable Frame Blending for redraw and rendering:
Select Enable Frame Blending from the Timeline window menu, or click the Enable Frame
Blending button ( ) at the top of the Timeline window.
Using three dimensions
Use the 3D switch ( ) to turn a layer into a 3D item that you can manipulate. When you
use the 3D switch for a layer, you can add camera and light layers to take full advantage of
the additional dimension.
For more information, see “Using cameras” on page 292 and “Using lights” on page 298.
Applying motion blur to layers
The Motion Blur switch creates a true motion blur based on the layer’s movement in a
composition and what you specify for the shutter angle and phase (see “Adjusting the
shutter angle for motion blur” on page 152).
Note: For information about the Directional Blur effect (called “the Motion Blur effect” in
earlier versions of After Effects), see online Help.
