Using Channel Ganging
Transport operations on Video Channels can be locked or “ganged” together to allow frame-
accurate key and fill material (either stills or clips) to be implemented. (See Using Ganging for Key
And Fill Operations on Page 72). Channel Ganging might also be used to create certain types of
presentations, such as synchronized matte backdrops on News Broadcasts.
Maxx 2400 can gang channels as follows:
1. Select a Channel Ganging Master channel. This can be channel 1, 2 or 3. To configure the
Channel Ganging Master Click EDIT->CONFIGURE->TIMING from the Main Menu. The
screen of Figure 33 is displayed.
2. Once the Master Channel is selected, any HIGHER NUMBERED channel may be ganged to
it by clicking the GANG checkbox in the Transport View of that channel. For example, if
Channel 1 is selected as the Ganging Master, channels 2,3 and 4 can be ganged to it. If
Channel 2 is the Ganging Master, channels 3 and 4 may be ganged to it and so on.
It is possible to gang channel 4 to channel 2 and leave channel 3 free for recording.

Using Ganging for Key And Fill Operations
Channel Ganging is most commonly used to support and Key and Fill operations. Ganging allows
generation of frame-accurate key and fill material (either stills or clips). This in turn is used with a
downstream keyer or video effects generator to be externally combined with a third video source.
Manual or automation control of the Master channel is all that is needed to play both the key and
the fill.
Key and fill clips are associated by their names. The Key Clip must have the same name as the Fill
Clip with a trailing underscore. Example:
Fill clip name: myfile
Key clip name: myfile_
