Transition Examples

Transitions go in the top-level transitions array. Each transition references two element id values via from_id (outgoing) and to_id (incoming).

Elements used in transitions must have an id set. For text and image elements, duration is also required.

Fade between two video clips. The time values create a sequential timeline; the transition overlaps the cut.
