A channel can have multiple outputs, one for each packaging group associated with a source. We are only using HLS in this workshop, but DASH and CMAF are also supported.
Specify index as the manifest name. Do not add a file extension as MediaTailor will do that automatically based on the format type.
Make sure you use the same source group you assigned back in step 3 otherwise your content will not be available to the channel.
Leave the default manifest duration at 60 seconds.
