Ganging Channels for Synchronized Playback
Two video channels can be ganged together for frame-accurate playback. This may be used for
key and fill material (either stills or clips), or multi-channel playout of presentations, such as
synchronized matte backdrops on News Broadcasts, or multi-screen projection of related images.
The channels can be ganged in the following combinations:

The channels can be ganged in the following combinations:
• Channel 1 controls Channel 2 and/or Channel 3 and/or Channel 4.
• Channel 2 controls Channel 3 and/or 4
• Channel 3 controls Channel 4
• Channel 2 controls Channel 3 and/or 4
• Channel 3 controls Channel 4
To configure Channel Ganging Click EDIT->CONFIGURE->TIMING from the Main Menu. The

Using Ganging for Key-and-Fill or 3D Playback
Channel Ganging is used for frame-accurate playback of stills animated sequences that have
an alpha, or key, channel. These in turn are fed to a downstream keyer or video effects generator,
to be combined with other video content. Manual or automated control of the Master channel is all
that is needed to play both the key and the fill. The MAXX-2400HD can also be used to play two
synchronized channels for 3-D applications.

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_
There is no provision for automatic loading of similar named clips on more than two
channels—the Master channel and the next higher numbered Ganged channel.
Proper key and fill operation requires two clips of identical length. This can be accomplished
by editing with head and tail trim.
Channel 3 is ganged to Channel 4 in the following example:
When a clip is opened/cued on Channel 3, the server automatically looks for another clip with
the same name, plus a trailing underscore. If the clip is found, it is loaded on Channel 4. The
Channel 3 clip contains the “fill” material, while the Channel 4 clip contains the “key” (or alpha)
file.
