This setting disables screen save for the current session.
This setting is not stored over a reset / power on.
19.16.9 Reduced rate Output
By default MagicQ sets the reduced rate Output to “Mixed + Changes only”. This reduces the amount of
network/usb traffic when DMX values are not changing. It also interleaves the ArtNet frames so that
ArtNet devices with small buffers will still be able to decode the correct ArtNet universes on heavily
loaded networks.
Consoles and PC installations that have been programmed on older versions of MagicQ software will
automatically have this option turned to “Mixed + Changes only” when the system is first started after the
upgrade. Users can change the setting back to the previous setting if required. The previous setting
“Normal” has been renamed “Continuous”. We recommend using the “Mixed + Changes only” option as
your normal setting particularly when using wireless networking.
Data packets sent to WWIWYG and Capture are sent only when the data changes – thus significantly
reducing network traffic when data is not changing. The “reduced rate DMX” options do not affect the
WYSIWYG or Capture data.
The DMX data sent to MagicQ Wings and Interfaces is only sent when the data changes – this reduces
USB data traffic. When the data is constantly changing there will be no difference. The RX data LED on
MagicQ Wings & Interfaces shows the level of DMX traffic – when DMX data is not changing this LED
will flicker a few times a second instead of being on constantly.
Some older DMX equipment is not able to work at full DMX speed. Use this option to reduce the DMX
refresh rate – note that this option reduces the rate of data MagicQ sends ve rthe network or via USB to
the interface. It may not affect the actual DMX rate as this may be under control of the interface itself.
Some Ethernet Interfaces and network hubs are unable to handle high levels of Ethernet traffic, for
example all 18 MagicQ universes output simultaneously. On these devices set this option to “Mixed +
Changes” – this sends the Ethernet data at the same rate, but in alternating order, thus ensuring that the
Ethernet Interface can pick up the data.
Note that MagicQ will always send data on ArtNet and Visualiser at least once every second regardless of
whether data has changed.
19.16.10 Movie Buffer frames
MagicQ uses buffering for Movie clips. By default (when this settting is set to 0) MagicQ uses a buffer
size of 128 frames. MagicQ will always use a minimum of 128 frames regardless of this setting.
Note that on Pro 2010 consoles MagicQ uses a solid state disc so on these systems changing this
parameter should not make significant difference.
