Apple DVD Studio Pro 4 - Manual (Page 473)

A new subtitle clip appears, with its duration matching the time between the two markers.
See the next section,
Configuring a Button over Video Subtitle Clip , for information on
configuring the subtitle clip to provide buttons over video.
Configuring a Button over Video Subtitle Clip
To configure a button over video subtitle clip, you first add the text or import the graphic
to use for the button or buttons, and then configure the buttons much as you would
when creating a menu.
Using an Overlay Graphic
The first step to creating a button over video subtitle using an overlay graphic is to import
the overlay graphic into the subtitle.
To import an overlay graphic for a button over video
1 Select the subtitle clip that you previously created to configure for buttons over video.
2 Click Choose in the General tab in the Subtitle Inspector.
3 In the dialog that appears, select the graphics file to use, then click Choose.
The graphic appears in the Viewer tab, using the current settings in the Colors tab.
Using Text Buttons
The first step to creating a button over video subtitle using subtitle text is to enter the
text in the subtitle. You need to set its font and position before proceeding with creating
buttons from it. See
Formatting Subtitle Text and Positioning Subtitle Text over the Video
for more information.
Creating the Buttons for Button over Video Subtitles
Once you have imported the overlay graphic or entered the button text, you can create
the buttons. To create the buttons, you create active area rectangles by dragging over
each button’s area. See
Adding Overlay-Based Buttons for details on this process.
The number of buttons you can have depends on the track’s aspect ratio setting, set with
the Display Mode pop-up menu in the General tab in the Track Inspector.
See Choosing an Aspect Ratio for more information on these modes. Also see What
Happens with Different Aspect Ratios? for issues that occur when creating buttons over
video on a 16:9 track.
