So I could embed a video in a web page. A man, say, walking up to a wall that has two doors. The video stops? pauses? I click the left side of the video,say--and the left door opens, and the video continues with him going through it? And if I click the right side, the right door opens and the video continues with him going through that door? Or do we jump to another web page, a new video, the man going thru the left or right door?

In html I can already put text below a video, giving the option to go left or right--but only by jumping to a new html page which will have the appropriate video. Clicking the video itself--somehow putting layers/triggers over it--I've never tried, but it does sound interesting.

The project is not placed on a web page. Its played through a player capable of reading all the information that make up a story. But in theory I guess you could make it as web page, that loads a new page all the time. However i find it annoying to having to wait for movies, sounds, objects etc to load, so doing it offline will improve speed so it becomes more like a movie.

But you are correct the whole movie would be made up by small movies corresponding to what selections are made. So the example you use could be the case.

I don't think there would be any problem in doing it in html if you wanted. But since it started as a personal project and i commonly ran into problems keeping track of things. The editor have a built in functionality that will do this for you, so when working on a given scene/page, you will be able to see all the input pages that leads to it and at the same time you can see all the output pages that the one you are working on leads to. So it makes it fairly easy because you can use this overview to quickly navigate through the story etc as you built it.

Also there are no limitation of how you organize your things, so you can have video playing on top of other videos, images on top of video etc.

Hope that answers your questions.
