#accessibility ⇒ `String`

If the WebVTT captions track is intended to provide accessibility for people who are deaf or hard of hearing: Set Accessibility subtitles to Enabled. When you do, MediaConvert adds accessibility attributes to your output HLS or DASH manifest. For HLS manifests, MediaConvert adds the following accessibility attributes under EXT-X-MEDIA for this track: CHARACTERISTICS=“public.accessibility.describes-spoken-dialog,public.accessibility.describes-music-and-sound” and AUTOSELECT=“YES”. For DASH manifests, MediaConvert adds the following in the adaptation set for this track: <Accessibility schemeIdUri=“urn:mpeg:dash:role:2011” value=“caption” />

. If the captions track is not intended to provide such accessibility: Keep the default value, Disabled. When you do, for DASH manifests, MediaConvert instead adds the following in the adaptation set for this track: <Role schemeIDUri=“urn:mpeg:dash:role:2011” value=“subtitle” />

end

#style_passthrough ⇒ `String`

To use the available style, color, and position information from your input captions: Set Style passthrough to Enabled. MediaConvert uses default settings when style and position information is missing from your input captions. To recreate the input captions exactly: Set Style passthrough to Strict. MediaConvert automatically applies timing adjustments, including adjustments for frame rate conversion, ad avails, and input clipping. Your input captions format must be WebVTT. To ignore the style and position information from your input captions and use simplified output captions: Set Style passthrough to Disabled, or leave blank.
