Asset movie, Alpha channels – Apple DVD Studio Pro 4 User Manual
Page 117
When you open DVD Studio Pro, it looks in two locations for transition asset folders:
• At the root of your disk, in this location: [root]/Library/Application
Support/Final Cut Studio/DVD Studio Pro/Transitions/
• In your home folder, in this location: [user]/Library/Application
Support/Final Cut Studio/DVD Studio Pro/Transitions/
Note: If you add a transition folder while DVD Studio Pro is open, it is ignored until the
next time you open DVD Studio Pro.
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 transition asset folder and can have
an extension. For example, if the transition asset folder’s name is Spinning DVD, the asset
movie could be named Spinning DVD.mov.
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.
There are two optional aspects to the asset movie: an alpha channel and a switch point.
Alpha Channels
In the example with the spinning DVD flying by discussed in the previous section,
, 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 in
).
