Input The track that you want to process.
NumParallel The maximum number of CPU threads to use for analysis.
SegmentDuration The maximum duration of a record in the SegmentedResult or SegmentedResultWithSource track.

Output Tracks

Output track Type Description Output1This column indicates whether the information contained in the track is included by default in the output created by an output task (when you don't set the Input parameter for the output task).
Data DemographicsResult Contains one record, describing the analysis results, for each input record. No
DataWithSource DemographicsResultAndImage The same as the Data track, but each record also includes the source frame. No
Result DemographicsResult Contains one record, describing the analysis results, for each detected face. Yes
ResultWithSource DemographicsResultAndImage The same as the Result track, but each record also includes the best source frame. No
SegmentedResult DemographicsResult

(Available only when processing video). Contains one or more records, describing the analysis results, for each detected face. The maximum duration of records in this track is limited by the parameter SegmentDuration, so multiple records are created with the same ID when a face remains in the scene for longer than this duration.

Yes
SegmentedResultWithSource DemographicsResultAndImage (Available only when processing video). The same as the SegmentedResult track, but each record also includes the best source frame. No
NOTE:

To use the SegmentedResult or SegmentedResultWithSource tracks, ensure that the input for the face demographics task is the DataWithSource track produced by face detection.
