Soloing a layer
You can isolate one or more layers for animating, previewing, or rendering by soloing.
Soloing excludes all other layers of the same type from appearing in the Composition
window. For example, if you solo a video layer, any lights and audio layers are unaffected,
so they appear when you preview or render the composition. However, the other video
layers do not appear. Soloing is useful for speeding up redraw and rendering.
To isolate a layer:
In the Timeline window, select the layers you want to isolate, and choose Layer >
Switches > Solo to add a checkmark next to the Solo command.
The Solo icon ( ) appears in the switches panel to the left of the layer names in the
Timeline window. You can also click this icon to toggle soloing off and on for a layer.
Understanding trimming
You can trim (hide) footage at the beginning or end of a layer, changing which frames are
first or last in the composition. The first frame to appear is called the In point, and the last
frame is called the Out point.
