To these and Troy's comments, I'd add:

    - preview (ie display a 'live' video input, without necessarily making a
movie)

    - grab individual frames from a 'live' source as a Rev image, whether or
not the source is being displayed on screen

    - open an existing movie, traverse the media and tracks, read the
properties (timebase etc), retrieve poster frame or frame at a given time as
a Rev image

    - create a new movie, add tracks, add data either from other movies, or
by (in the case of video tracks) specifying a Rev image and the time

    - access to the QT user interface dialogs

Um... and no doubt more!
