Captions formats supported in Microsoft Smooth outputs
In this table, look up your input container and captions type. Then read across to find the caption formats that are supported in MediaLive in a Microsoft Smooth output, when you have this input container and captions type.
Note
You can also produce subtitles without a caption source in your input. Enable the Smart Subtitles feature, which uses AWS Elemental Inference to generate TTML subtitles from the audio. For more information, see Smart Subtitles using Elemental Inference.
