Instance Property

enablePostProcessing

A Boolean value that indicates whether post processing is required for the video composition instruction.

Declaration

var enablePostProcessing: Bool { get set }

Discussion

If no post processing is required for the whole duration of the video composition instruction, set this property to false to make the composition process more efficient.
