destinationType property
Specify the format for this set of captions on this output. The default format is embedded without SCTE-20. Other options are embedded with SCTE-20, burn-in, DVB-sub, IMSC, SCC, SRT, teletext, TTML, and web-VTT. If you are using SCTE-20, choose SCTE-20 plus embedded (SCTE20_PLUS_EMBEDDED) to create an output that complies with the SCTE-43 spec. To create a non-compliant output where the embedded captions come first, choose Embedded plus SCTE-20 (EMBEDDED_PLUS_SCTE20).
