Help Using Help Reference Back 111 Description The LayerCollection add() method creates a new AVLayer containing the given AVItem, and adds the new AVLayer to the containing CompItem. This method generates an exception if the item cannot be added as a layer to this CompItem. The duration parameter, if provided, will affect the method only if the given AVItem contains a piece of still footage; it has no effect on movies, sequences or audio. If duration is provided, then the duration of the newly created layer will be the passed value. If duration is not provided, then the duration will be determined by the user preferences. Note that by default, user preferences proscribe that the duration be set equal to that of the CompItem into which the layer is being added. The preference can be changed to a specific duration. Choose Edit > Preferences > Import (Windows) or After Effects > Preferences > Import, and specify options under Still Footage. Parameters item duration AVItem to be added optional floating-point value specifying the length of a still layer Returns AVLayer.
