## Discussion

[`VTMotionEstimationSessionCreate`](/documentation/VideoToolbox/VTMotionEstimationSessionCreate) takes a dictionary of creation options, `motionVectorProcessorSelectionOptions`.
You can supply [`kVTMotionEstimationSessionCreationOption_UseMultiPassSearch`](/documentation/VideoToolbox/kVTMotionEstimationSessionCreationOption_UseMultiPassSearch) with `kCFBooleanTrue` to provide
higher quality motion estimation. True-motion achieves higher quality by running the motion estimator in multiple
passes. The default is `kCFBooleanFalse`.
