• Choose Layer > Quality, and then choose an option:
Best Displays and renders a layer using subpixel positioning, anti-aliasing, 3D shading, and complete calculation of
any applied plug-in effects. Best provides the slowest display and rendering time.
Draft Displays a layer so that you can see it, but only at rough quality. It displays and renders a layer without anti-
aliasingandsubpixelpositioning,andsomeeffectsarenotpreciselycalculated.Draftqualityisoftenthemostuseful
setting for general work and for video layers (to avoid blurring when matching compositions to raw video footage).
Wireframe Displays a layer as a box with an X across it. Layer wireframes are displayed and rendered faster than
those rendered with Best or Draft settings. However, layer contents or masks are not visible—only position and size.
Because of this limitation, wireframe quality is available only from the Layer menu.
You can set the default quality of new layers in General preferences; select or deselect Create New Layers At Best
Quality. (If this option is deselected, the default quality is Draft.) Duplicated or split layers retain the Quality setting
of the original layer.

To show and hide effects
UsingtheEffectswitch ,youcancontrolwhetheralayer’seffectsappearinbothpreviewsandrenderedversions.
When you deselect this switch, the layer is displayed and rendered without its effects, saving previewing and
rendering time. This switch is available only if a layer has effects applied to it.
Do one of the following:
• In the Timeline panel, click the Effect switch for a layer to toggle between showing and hiding effects.
• Select a layer, choose Layer > Switches, and make sure that the Effect command is selected (to show effects) or
deselected (to hide effects).
Note: You can temporarily turn on or off an individual effect applied to a layer.

Enhancing time-altered motion by blending frames
Use the Frame Blending switch to enhance the quality of time-altered motion in a layer that contains live-action
footage—video, for example. You can apply frame blending to a sequence of still images, but not to a single still
image. If you are animating a layer—for example, moving a layer of type across the screen—use the Motion Blur
switch .
