User Guide

112 Studio 8
Broadly speaking, a button is an area of the screen with
which the user can interact in some way. Buttons are
classified according to the action they produce when
the user activates them, and not by their appearance,
which generally should give a strong clue to their
behaviour, but is not required to. The four types of
button are:
• Normal: Clicking the button causes playback to
jump to a chapter (that is, ordinary video) or another
menu. The link between the button and its target is
created in the Clip properties tool, not in the Title
Editor.
• Thumbnail: This special form of the normal button
type displays a thumbnail frame (or a moving
thumbnail preview) from the part of the movie to
which it links.
• Previous: This button appears on the second and
later pages of multi-page menus (menus with more
links from normal or thumbnail buttons than will fit
on one page). It links to the previous menu page.
• Next: This button appears on all but the last page of
multi-page menus; it links to the following page.
The button art supplied with Studio includes several
examples of each type. Each button is an image file in
Targa (tga) format. Examination of the files in an art
program like Adobe PhotoShop or Paint Shop Pro will
show that the transparent portion of the button image,
and the special area for the display of thumbnails
(where applicable), are defined by an alpha channel
included with the image.
