I have an idea for linking a keynote presentation with a video (exported from a 3d tool). The idea is that each time you 'click' (as you would to move to the next slide/transition) it would play x more frames of the video then pause. So frame 1-30 might be the first animation, and it would pause on frame 30. Then, you click again and it plays 31-60, stopping on 60.
Is such a thing possible and if so how would I achieve it? Assume a video file is available in the required format.
