AVVideoCompositionInstructionMBS.containsTweening as Boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	AVFoundation	MBS AVFoundation Plugin	14.0	✅ Yes	❌ No	❌ No	✅ Yes	All

A Boolean value that returns whether the composition contains tweening. (required) (read-only)

If YES, rendering a frame from the same source buffers and the same composition instruction at two different compositionTime may yield different output frames. If NO, two such compositions will yield the same frame.

The media pipeline may be able to avoid some duplicate processing when this property is set to false.
Available in OS X v10.9 and later.

AVVideoCompositionInstructionMBS.enablePostProcessing as boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	AVFoundation	MBS AVFoundation Plugin	13.2	✅ Yes	❌ No	❌ No	✅ Yes	All

Indicates whether post processing is required for the video composition instruction. (read-only)

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.

AVVideoCompositionInstructionMBS.passthroughTrackID as Integer

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	AVFoundation	MBS AVFoundation Plugin	14.0	✅ Yes	❌ No	❌ No	✅ Yes	All

Returns the track ID if a single source frame should be displayed for the duration of the instruction. (required) (read-only)

If for the duration of the instruction, the video composition result is one of the source frames, this property returns the corresponding track ID. The compositor won't be run for the duration of the instruction and the proper source frame is used instead.

The dimensions, clean aperture and pixel aspect ratio of the source buffer are matched to the required values automatically.
Available in OS X v10.9 and later.

property	AVFoundation	MBS AVFoundation Plugin	13.2	✅ Yes	❌ No	❌ No	✅ Yes	All

The time range during which the instruction is effective. (read-only)
