the DOG animated off a split second before the switch back, I wonder why?
Normally when the pres suite take their mixer into emergency cut, the bug disappears entirely. Not seen it do something like that before.
Although it might not be what happened in this case, the bug does stay on with emergency cut on Showcase, along with BTS3, because of the slightly different system they run on compared to 1 & 2, where it would indeed dissappear.
Most of the time, if you see a bug quickly disappear and then reappear in the same place, it means the automation is taking into a new event - as far as the automation's concerned, the bug has to animate off as it is at the end of a part, and then reappear as if it is the start of a new part. For example, a new event with a different source might be placed next in the schedule as another way of getting that source to air.
Quite often you'll see this happen with the bug if a live event is crossing the 6am threshold, because that's when the new broadcast day starts and for the sake of the schedulers and the 'as-run' reports, a second event with exactly the same source as before 6am is taken into. It's for the same reason that even across most channels that show nothing live, you'll see an event (bumpers, idents, programmes - depending on the channel) always start at dead on 6am every morning.
