QTMCC 06 - Stepping through a PICT Movie (15-Sept-95)

Q I've been trying to use QuickTime to step through a movie of PICTs activated by key input (hit a key and the next frame is displayed). My problem is I can't get consistent steps.

What's the easiest way to move to the next frame?

A The easiest way is to use a Movie Controller to accomplish this. The controller does not need to be visible, but it must reside in the same grafPort as your movie. You can send mcActionStep to the controller to bump the movie to a new frame.
See chapter 2 of Inside Macintosh: QuickTime Components for complete details on using a Movie Controller, pp. 2-3 to 2-75.
