Configuring the Buttons for Button over Video Subtitles
Once you have created the buttons, you need to configure them. There are three areas
to configure:
• Button navigation: Sets how a viewer jumps from one button to the next using the
remote control’s arrow buttons.
• Button targets: Sets the connection for each button (what is jumped to when the button
is activated).
• Color mapping: Sets the colors that appear for the normal, selected, and activated
button states.
Button Navigation
Configuring button navigation with buttons over video is exactly the same as configuring
the navigation in menus. By default, the navigation is assigned continuously, with
DVD Studio Pro automatically setting the arrow button actions for each button. You can
disable this function and set the navigation manually if you prefer.
See Configuring Button Navigation for details on the methods you can use.
Button Targets
Configuring the targets for each button with buttons over video is almost exactly the
same as configuring the button targets in menus. You have the option of setting them
in the Connections tab (the buttons appear as marker items), in the Subtitle Inspector,
or by using a shortcut menu in the Subtitle Editor.
The difference is that a button within a track cannot select a specific stream in a different
track. For this reason, the stream settings for buttons in subtitles are inactive if the target
is set to anything other than “not set.”
If you need a button within a track to select a specific stream in another track, you can
set the target to run a script that’s configured to jump to the desired stream.
See Setting a Button’s Connection for details on each method.
Color Mapping
Configuring the color mapping for the buttons with buttons over video is similar to
configuring the color mapping for an advanced overlay with a menu.
