2.5 Use Case View Renderengine Use

EDL Example1

A simple example showing how the actual objects are placed in the Fixture (=definitive playlist). It shows a Video and Audio clip placed on two tracks

EDL Example2

More complex example showing the Object graph in the EDL and how it is linked into the Fixture to yield the actual locations. In this example, an HUE Effect is applied on a part of the Clip

Engine Example1

Example1 (from EDL) continued: here the RenderEngine to be created by the Builder from the Input shown in Example1

Engine Example2

Example2 (from EDL) continued: notably in this RenderEngine the Effect has been partitioned into 2 segments with constant configuration.
