General Concept

With Scene Transitions (or Transition Scenes), Ventuz can seamlessly blend two Scenes or Templates. The Transition Scene holds the current on-air Scene, and the cued Scene in a Scene Port. Because of this, it is possible to blend the two Scenes together to enable Ventuz to make both Scenes visible at the same time.

To use Transitions, every Template in Director has a tab with Transition, to add a built-in Transition or custom Transitions. The Transition is always added to the cued Template and will be placed between the (default) Layout Scene and the Template Scene when cued. Because the Scene Transition holds both Scenes, the engine has to validate and render both. When both Templates are in the same Scene, the Scene is loaded twice to perform the Transition.

Please Note: during a transition, Ventuz will render both Scenes at the same time; Please ensure that all systems that will be using these transitions can handle the extra load of two scenes running simultaneously

Technical Setup

The Transition Scene is a standard Ventuz Scene with a specific configuration, to work as Transition Scene:

In General, every animation between these two Ports is possible. For a detailed description see the: How To Build a Scene Transition.

The Animation section of a the Transition Scene behaves the same way as a standard Template does. Data channels added to the Animation Data are accessible when the Transition is cued and useful for creating custom Transitions. The default duration is determined by the duration between the Begin and Present state and is changeable when cued.

Cue and Take Process

This graphics shows the process of a cue and take with a Transition in the Scene Tree window, with an break-down below:

Control and Information

With the Transition Info Node the status and state of the Transition Scene is available. This node is useful when building custom logic to trigger events that depend on the progress of the Transition.

The Audio Incoming and Outgoing channel within the Transition Scene can control the Audio output channel in the Template Scene, where it can control the audio level of a bound movie clip node.

Timing

The timing of Templates together with the Transition is shown below:

Depending on the length of the Template animation, the Transition will align relatively different.

Director

The Director has built-in Transitions in a separate Transition window. To use custom Transitions, they must be part of the Published Scenesin the same way Templates are. If there is a new .trans Scene in the directory, Director will ask to add it. To add it manually, you can find it in top menu bar: Show -> Project -> Published Scenes.

All Transitions are selectable in the Transitions window and added by dragging onto the cued Template's animation tab. The duration and all Transition Data can be changed for all Transitions and if used.
