Move On Dark


By default Move On Dark will be enabled. When this function is enabled for the playback, whenever a fixture goes dark (it’s intensity falls to zero, or the shutter is closed), ZerOS will look ahead in the playback to upcoming cues to see what values the colour, beam, shape and position parameters are next programmed at for that fixture. Although this is called Move On Dark, this isn't just for position parameters - this is for Colour, Beam and Shape too.

It will then output those values after the fixture has gone dark (according to the Move On Dark delay and fade times). When the fixture comes back on again in a later cue, the colour, beam, shape and position parameters will already be at their correct values and just the intensity will fade up or the shutter open. 

Move to First Cue

This option is used when there are no more cues later in the playback for the fixture to Move on Dark to. If enabled, when fixtures go dark for the last time in the playback, they will move to the first cue they are used in. When disabled, once the fixtures go dark for the last time in the playback, they will not move.

Fade Time

This is the time it takes for the fixture's parameters to move to the values that they are in the next cue they're used. The default is 3 seconds, as this keeps larger older moving lights quieter when being prepared for when they're next used.

Delay Time

When a fixture goes dark, the delay time can be used to delay the fixtures, prior to them fading to their values using the fade time. The default is 1 seconds, meaning when a fixture goes dark, it waits a second, and then fades to the values required for the upcoming cue.

Don’t Move...

This option allows you to disable a specific attribute from moving in dark across the whole playback. By default, only “Don’t Move Effect” will be enabled, indicated with a red stripe.
