Instance Property

enablePostProcessing

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

Declaration

var enablePostProcessing: Bool { get }

Discussion

A value of false indicates that no post processing is required for the whole duration of the video composition instruction. The composition process is more efficient if the value is false.

The value is true by default.
