Apple DVD Studio Pro 4 - Manual (Page 471)

Referencing Graphics Files in STL Subtitle Files
An STL subtitle file can contain a mix of text subtitle entries and references to graphics
files. You must use the $SetFilePathToken command in the file before any lines that
reference a graphics file.
$SetFilePathToken = _Graphic_
00:00:12:04 , 00:00:14:12 , _Graphic_RabidLemur.tif
00:00:16:14 , 00:00:19:08 , _Graphic_MooseLemur.tif
Important: Do not add spaces between the token ( _Graphic_ in this example) and the
filename.
The STL subtitle file and the graphics it references must be in the same folder. And, just
like the other assets that you import into your project, the graphics files must not be
moved, renamed, or deleted until after you build your project.
Creating Buttons over Video
Having buttons appear while a track plays can be a very useful navigational tool, providing
the viewer with options that can significantly add to the DVD title’s value. For example,
you can use buttons over video to allow the viewer to jump from the current track to a
track containing related information, such as an interview of an actor, a news clip, or an
explanation of how an effect was done.
How Do Buttons over Video Work?
DVD Studio Pro uses subtitles at specially configured markers to provide the buttons over
video feature. You configure the buttons exactly as if you were configuring a standard
menu using advanced overlays: You create each button’s active area, assign its connection,
set the button navigation (if you use more than one button), and set up the color mapping
for the highlights.
Each subtitle containing buttons over video is tied to a marker. You must create a marker
at the point where the subtitle should appear, and another where it should disappear.
You can mix standard subtitles in the same stream as button over video subtitles.
You can only view one subtitle stream at a time. Because the buttons over video feature
uses a subtitle stream, you effectively disable the normal usage of subtitles on the title
while the buttons over video stream is selected. (Although a subtitle clip can have both
buttons and subtitle text, often the buttons need to appear longer than normal dialogue
text.) In most cases, you would configure the title so that the viewer decides whether to
enable buttons over video by selecting a button on a menu. When selected, the subtitle
stream that contains the buttons is usually configured to be forced to display so that the
viewer does not inadvertently turn it off.
