Captions are text overlays that can span key frames in storyboards. Changes you make to caption settings are reflected immediately in the storyboard.
You can specify that two captions appear at the same time in the storyboard. The captions will be stacked vertically in the track, based on their assigned Location.
Start time is current position of caption in the storyboard. Drag the caption to a different position, change the start time.
If you select Fade, specify how long the transition will last.
Specify any of the following:
Select Text Only to format the contents with standard text formatting options (text font, size, emphasis, color, alignment, and outline effect color).
Select HTML to use HTML tags to format the text. When you use HTML tags, you can include hyperlinks and images, as well as HTML text formatting.
Specify anchor point for the caption: Top Center, Bottom Right).
By default, the text is opaque.
Resize the caption by specifying a percentage of the frame for it to cover with the Size X and Size Y settings.
The maximum height of the caption is one-half of the frame. The size is relative to the size of the window in which the storyboard is displayed.
Fine-tune the caption position using the OffsetX and OffsetY settings.
