Let’s spend a moment considering the purpose of transitions as this relates to design and the order of operations in the Animation Store Creator software.
Setting aside all other aspects, a properly prepared transition accomplishes one of two things:
Applied to the live production suite’s Background video layer, it will ultimately swap the displays from the current Program and Preview row sources.
Or applied to an Overlay and DSK channel, it will introduce another source (commonly a title or graphic, but not limited to those options) to appear ‘above’ (or ‘in front of’) the Background video layer and remove it from view if the transition is run in reverse.
In both cases above, the transition manipulates two sources of imagery, which we can refer to as source A and source B:
At the beginning of a transition, only source A is displayed.
Source B is introduced as the transition progresses, either replacing source A (when the transition is applied in the Background channel) or appearing superimposed above it (when applied to a DSK/Overlay channel).
An Overlay Animation constitutes an added source displayed above both source A and source B during the course of the transition, being completely removed from view when the transition ends.
In all cases, the way source B is introduced is governed by the controls and animation content (if any) you supply in the Wipe/Warp Sequence control group, discussed a bit later in, and by the Effect Type menu setting – discussed next.
