I have a question about authoring multiple movies to a DVD. Here's the basic idea. I have 2 separate films that I want to be able to access from the main menu. This will lead to a separate menu for that particular movie. From there I want to be able to access chapters and so forth for that movie.
I also have a book pdf that I would like to be able to access from the main menu, so that the viewer can access it and flip through the pages like a book through the DVD player (i.e. not as bonus media via the computer, etc.)
The multiple movie ideas is very easy, just create a firstplay menu which allows you to choose which movie menu you want them to be directed to. For each movie, create a menu with a Play button, and a chapters button. Have the Chapters button select a new menu, where you create buttons for every chapter, attached to each of the chapter points in that particular timeline. It's about as simple as it gets.
As far as the .pdf is concerned, you will need to convert each page of the .pdf to a .jpg, or .psd, taking into account for the aspect ratio change, and title safe zones. Create menus for each page, and create forward and back buttons to allow them to navigate through the pages. Remember, that you are dealing with 720X480 resolution, so small print may be a problem for reading. You might need to chop your pages in two, so that they will fit the page, and have enough resolution and be large enough to be read on a TV.
