Description

The AVLayer object provides an interface to those layers that contain AVItem objects composition layers,
footage layers, solid layers, text layers, and sound layers.

• AVLayer is a subclass of Layer. All methods and attributes of Layer, in addition to those listed below, are
available when working with AVLayer.
• AVLayer is a base class for TextLayer, so AVLayer attributes and methods are available when working with
TextLayer objects.

Example

If the first item in the project is a CompItem, andthe first layer of that CompItem is an AVLayer,the following
sets the layerquality, startTime, and inPoint.
var firstLayer = app.project.item1.layer1;
firstLayer.quality = LayerQuality.BEST;
firstLayer.startTime = 1;
firstLayer.inPoint = 2;
