Scene Graph

Scene Graph

The Montagix SDK utilizes a Scene Graph as its backbone for media composition and editing. This provides a clear and organized way to structure media elements, control timings, and apply effects or transitions.


A Scene Graph is a structure that encapsulates the entire media scene, representing clips, layers, transitions, and effects. With Montagix SDK, you don't have to create a Scene Graph from scratch; it's already provided. Your primary interaction will be to populate the graph with nodes, such as media clips or effects, and dictate how they connect and behave in relation to each other.
