Permitted range is [1 ..30,000]. In a FootageItem, height is linked to the height of the mainSource; in a CompItem, it is linked to the height of a composition. It is legal to change the height of a CompItem or a FootageItem whose mainSource is a SolidSource. It is an error to change the height if the item is a FootageItem whose mainSource is not a SolidSource. Type Integer; read-only unless a CompItem. AVItem name attribute app.project.item(index).name Description The name attribute is the name of the object as shown in the Project window. In a FootageItem, the name is linked to the mainSource.

AVItem pixelAspect attribute app.project.item(index).pixelAspect Description The pixelAspect attribute determines the pixel aspect ratio of a given item. Permitted range is [0.01 .. 100]. In a FootageItem, pixelAspect is linked to the pixelAspect of the mainSource; in a CompItem, it is linked to the pixelAspect of a composition. Certain pixelAspect values are specially known to After Effects, and will be stored/retrieved with perfect accuracy. These are the set { 1, 0.9, 1.2, 1.07, 1.42, 2, 0.95, 1.9 }. Other values may experience slight rounding errors when you set them and get them. Thus, the value you retrieve after setting may be slightly different from the value you supplied.
