Specify the format for this set of captions on this output. The default format is embedded without SCTE-20. Note that
your choice of video output container constrains your choice of output captions format. For more information, see
https://docs.aws.amazon.com/mediaconvert/latest/ug/captions-support-tables.html. If you are using SCTE-20 and you
want to create an output that complies with the SCTE-43 spec, choose SCTE-20 plus embedded. To create a non-compliant
output where the embedded captions come first, choose Embedded plus SCTE-20.
