This panel consists in a timeline–style interface that represents both the elements capable of being transitioned or animated, and the transitions themselves, grouped by type.
The transition type refers to the event that triggers the animation of the elements: an Overlay switching IN and OUT, or a pagination of a Dynamic Content List, be it manually or auto-cycling.
Transitions Panel Interface
(1) Transition Type tabs: Select which transition to edit for the currently focused element.
(2) Transition Phase and controls: Switch between editing the different moments of the transition, and trigger previews for the current transition. These controls will change according to the transition type.
(3) Transition Tree: Is very similar to the main Elements Tree. Here you will see every element that can be animated in the scope of the current transition type. We'll cover more about scopes below.
(4) Timeline: It is the visual representation of all the Animations of the elements in the current transition. The length of an animation block represents the animation duration, and the position relative to the time ruler represents the delay.
(5) Animation inspector: Just like in the main Elements Inspector, here you will see every configurable parameter of the selected Animation, which will be highlighted in the Timeline.
(6) Timeline options: Change the zoom level, toggle between different time scales (milliseconds, 30 fps, 60 fps), or enable/disable snapping when dragging Animations.
Transition ScopesWe call scopes to the different subsets of elements of your Scene that can be animated for each Transition Type.
Both Overlay IN/OUT and List Pagination transitions are basically an orchestration of animations of several elements after a specific event (e.g. setting the Overlay IN or going to the next page).
On Overlay IN/OUT transitions, all of the elements that belong to the same Overlay can be animated together. So, when you select an Overlay or any of it descendant elements, you will see all of them listed in the Transition Tree, up to the Overlay itself, but not other Overlays.
Update Animations only apply to the element whose value or content changes. They don't apply to sibling or parent elements. This is the main difference with Overlay IN/OUT transitions, which can affect all the elements contained in an Overlay.
For List Pagination transitions instead, the elements capable of being orchestrated together after a page change are all the elements that are descendants of the List that fires that pagination event. So, you will only see the List Item and its descendants on the Transition Tree.
During pagination transitions, we have the current elements Leaving the scene and the new ones Entering.
On the Update Animations, this kind of transition will handle the animations for the element’s old value (leaving) and new value (entering).
Tree and Timeline
You'll find each element in the current transition scope represented as a track on the Timeline. The focused element's name will be slightly highlighted as a visual reference.
Those coloured blocks you see on the tracks represent the Animation applied to each element. There can only be one Animation per Element per Transition Phase.
Below the Timeline Inspector you will find some general view-related controls:
"Snap to ruler" toggle: When turned on, dragging and resizing animations in the timeline will snap to the time ruler marks.
Time format: Choose the scale and format used in the time ruler and timecode.
Keep in mind that this scale is just a visual reference for everyone used to work in "frames per second" tools.
Changing it will not affect the animations frame rate, which will always try to reach 60fps. Since our Graphics are rendered using HTML, this frame rate will always depend on the browser and device where the live Graphics is displayed.
Zoom slider: Work at the microsecond level or view your entire transition at a glance. You can also use ctrl + mouse scroll or trackpad's pinch gesture when hovering the timeline to zoom in and out.
