Synchronizing Content

Network Synchronization Capabilities

As currently implemented, it is possible to synchronize movie playback as well as certain graphics
effects.
Movie Playback Synchronization ensures that movie playback between multiple servers stays
Synchronized for either collage applications or where multiple servers are playing the same
movie clip on different projection surfaces. It is especially useful for long movie clips and will
solve the problems of frame drift that can be associated with media server playback.
Certain effects in the graphics engine can also be synchronized between servers. Effects such as
the ripple effects, object wobbulation, or color cycle effects need to be synchronized between
servers to appear correctly in Collage usage scenarios.

Programming Synchronization

To program synchronization, first start by deciding which fixture/server will be the master server.
This can be any server on the network. However, in a case of mixed computer hardware in the
servers, the oldest server should be chosen as the master. This will ensure that all of the servers
have the ability to playback content as well as the master server.

Sync To Parameter

Once you have chosen your master server, the Sync To parameter must be set on all of the slave
servers. This parameter is found on the first Global Layer of each server. The Sync To parameter
is set to a value equal to the Fixture ID of your master server. For example, if your master server
has a fixture ID of "3", all of the slave servers should have their Sync To parameter on Global
Layer 1 set to "3".

Sync Mode Parameter

DMX Default Value: 0 = no sync mode selection
Next, set the Sync Mode parameter to its appropriate value. These are for synchronizing movie
playback on any Graphic Object. If all Graphic Object 1s need to synchronize together, set the
Sync Type parameter on all Graphic Object 1s of the slave servers to Graphic Object 1. The
same goes for synchronizing all of Graphic Objects 2–9. It is possible to synchronize Graphic
Object 1 to Graphic Object 3, etc., as long as all of the appropriate parameters are set correctly.
NOTE: Unlike the Sync To parameter, Sync Mode does function on all graphic object
layers and must be set in order for Synchronization to function correctly on
that particular layer.
