Advanced Operations
Create Primary and Secondary M/Es (Dual Feed)
324
Multiple Feeds
Starting with the example in Create Primary and Secondary M/Es (Dual Feed) , on page 324,
you could chain additional M/Es for multiple feeds. This should be planned carefully but
once configured, the entire show can be switched from the Primary ME thus simplifying a
very complex set of operations.
Including Source Substitutions
Source substitutions can also be a powerful part of chained M/Es. They can be used to cut
on two or more different sources for the chained M/Es and switched from the Primary ME.
For example during a “Home” verses “Away” baseball game, the Primary ME could take a
camera source in the Home team’s dugout on Source 1 but take a different camera on
Source 11 on the Secondary ME in the Away team’s dugout using the source substitution
(see Bus Linking Source Substitution Tables , on page 166).
Source substitutions could also be used across multiple feeds for different languages or for
paid cable verses network feeds and so on.
Transition Chaining is part of the Load Granularity pane in the File Ops, User Setups, Suite
Prefs menu.
About Corner Pinning
Corner Pinning allows you to move the corners of a source image relative to the source
plane of the image. Corner Pinning is keyframeable, with all standard path control
functions. The new corner locations do not need to form a rectangle.
Corner Pinning is accomplished by distorting the source to fit into its newly defined
corners. The modified image remains in its original source plane, and is not “bent” along
the Z axis. Corner Pinning does not change the location of the axis of rotation or spin of the
source image.
