Going to backup

Post by Phil » Wed Sep 17, 2008 1:30 pm

Just a quickie

I'm running a 2min cue, the desk falls over, the backup needs confirmation before taking over the show, the cue is still fading on the backup but no output. So when outputs enabled or confirmation of takeover there is a snap in levels live on stage.

Can the backup automatically takeover with no time delay?

I haven't tried it while a cue is running, but, if the tracking backup has the outputs enabled, it should automatically take over without the need for confirmation. You will still get the dialog box telling you it is taking over in 5 seconds, but at least this way it should continue the cue. In Hardware Setup | Console there is an item called "Force Outputs at Startup on Recovery". If this is enabled on the tracking backup, it should enable the outputs each time it is restarted without needing confirmation. Just make sure the main desk is up and running first before starting the tracking backup.

What Phil is talking about is if you are forced to go into backup while a cue is running. If this happens then the levels on the backup continue to change in cue time, but the backup is not outputting anything. If you select the backup to output immediately, you still have as much cue fade without output as it takes for the backup to automatically take over or for you to confirm takeover, which results in a sudden snap change on stage. What I think we need is for the cue to pause until control is completely handed over. Better to have the cue delayed for 5 secs than for a snap change on stage.

This is very similar to the way the 510 took over from a 520. The basic premise is that the backup has to be sure that the main has really died. Both the GeniusPro and Palette OS's have a time out period to verify that the main is really dead. In both cases this time out is around 7 seconds.

Trying to do it any quicker than that, might lead to the backup taking over when it did not need to, which would be a little undesirable.
