hi mike,

first off, there are many different strategies on how to do an interactive movie where you can choose different endings.

it can be done like the way you describe, although it might not be the best way to go about it. breaking up the movies into smaller consecutively loaded movies might be better, or even using multiple players to trick the eye into believeing things are seamless when they are actually not.

if you are intent on working with one long video, you will need to work with CUE_POINTS, encoding both event and navigation type cuepoints into your video to enable you to trigger events, and navigate to the correct points in the movie.

say you were doing 2 different endings, you could lay it out so the first choice plays from start to end. the second ending could start right after the first ending ends. for this set up(see image below), the minimum sequence of cuepoints needed would be an event c.p. at the point of change ( lets call it eventA), and an event c.p. where the first ending ends ( call it eventB), and a navigation c.p. at the beginning of ending 2 ( call it navigationA).

the yellow bar represents the films timeline for the beginniing up to the point of divergence.
the red bar represents the first ending
the blue bar represents the second ending

the top bar is the complete timeline
the middle bar shows how the common beginning plays, and goes right into the first ending, then ends
the lower bar represents the common beginning playing up to the point of change, then jumping to the second ending

i made a real crude example of this you can see here:

of course, this is describing it in its most simplest bare bones form. to deploy it for real, you would need to take many things into consideration, one being that cue points can't be accessed until they have buffered.

if you want more help with cuepoints, i'd be glad to help.
