Basic downstream key operations
The basic procedure for downstream keying is as follows.
Inserting a downstream key
In order to use a downstream key for text or graphics, it must first be imported
onto the internal hard disk of this unit. You can use the alpha channel of a
graphics file in targa format as the key source, which allows high-quality
downstream keying.
For details on importing a graphics file, see “Importing Graphics Files” (page 175).
