A transformation operation is selected based on capabilities of the target device and used to create an adapted version of the multimedia presentation from a source version of the multimedia presentation. The adapted version contains adapted media data corresponding to a source version of media data for the multimedia presentation. In one aspect, the adapted version of the multimedia presentation also includes adapted composition data corresponding to a source version of composition data for the multimedia presentation.
