If you choose Upconvert, MediaConvert includes the captions data in two ways: it passes the 608 data through using the 608 compatibility bytes fields of the 708 wrapper, and it also translates the 608 data into 708.
*)source608ChannelNumber : int option;Specifies the 608/708 channel number within the video track from which to extract captions. Unused for passthrough.
*)source608TrackNumber : int option;Specifies the video track index used for extracting captions. The system only supports one input video track, so this should always be set to '1'.
