Chapter 4 T2 Alpha Option
Option Overview
You can play/import movies containing transparency information and still images
(alpha embedded clips). In addition, you can play a playlist in which alpha embedded
clips and normal clips are mixed.
Alpha embedded clips in the list of the Browse or Bin tab are displayed with icons
indicating that they contain alpha.
If an alpha embedded clip is loaded to the P1 or P2 channel, the Fill data is output to
the channel where the clip is loaded and the Key data is output to the other channel
(Fill/Key output mode). The Fill side channel is shown as "Fill" and the Key side
channel is shown as "Key".
NOTE: Icons corresponding to Fill and Key are shown during the front panel
mode.
When you play a playlist that contains any alpha embedded clip, the system enters the
Fill/Key output mode and the Key side will output a black screen while a normal clip
is being played.
For more information about Fill and Key, see "What is Fill and Key data?" on
page 50 .
