Asset Movie

The asset movie is required if you want any kind of video other than the start and end

frames to appear during the transition. For example, if you want a spinning DVD to fly

across the screen during the transition, it is the asset movie that provides the flying

DVD image.

The asset movie must have the same name as the asset folder and can have an

extension. For example, if the asset folder’s name is Spinning DVD, the asset movie

could be named Spinning DVD.mov.

The asset movie can also include an alpha channel. In the above example with the

spinning DVD flying by, you would most likely want to be able to see the start or end

frame video through the DVD’s hole and around its edges. For this to happen, there

must be an alpha channel for DVD Studio Pro to know which parts of the asset movie

video should appear and which should be ignored.

There are two ways to provide this alpha channel: embedded with the asset movie or

as a separate asset matte movie (described later).

When the alpha channel is embedded with the asset movie, be sure the video output is

premultiplied, or shaped, by the alpha channel. In other words, the video output

should be transparent or opaque as defined by the alpha channel.

Note: Normally, the transition background matte movie (described later) controls

which areas of the background show the start and end video frames while the

transition plays. If there is no background matte movie, DVD Studio Pro switches from

using the start frame video as the transition’s background to using the end frame video

as the background at the asset movie’s halfway point.

The asset movie provides

transition video in addition to

the start and end frames.

The asset movie can

contain an alpha channel

to control where the

background appears.
