    I don’t understand why a general media type description is assigned to an instantiation. Seems like this would be better placed within the overall . Because whether an moving image is an mp4 file or on a VHS tape, it’s still a moving image.

    Hey Amanda, For instance today’s Democracy Now episode as an asset is not really moving image or audio. The instantiations include a CD, DVCam tape, mp3, mp4. Some of those instantiations are a ‘moving image’ media type, some are ‘sound’ media type. A printed transcript for be another, though all the instantiations are renditions of the asset in different forms.
