Description
The width attribute specifies the width, in pixels, of the item. Permitted range is [1 ..30,000].
In a FootageItem, width is linked to the mainSource's width; in a CompItem, it is linked to the comp's width.
It is legal to change the width of a CompItem or a FootageItem whose mainSource is a SolidSource. It is an
error to change the width if the item is a FootageItem whose mainSource is not a SolidSource.
Type
Integer; read-only unless a CompItem.

solid layers, text layers, and sound layers).

available when working with AVLayer.
