Audio Description
audio-descriptionScript-then-render accessibility: a reviewable dub + AD script, voiced and mixed only after approval.
Make a video accessible in two async stages. Stage 1 writes the complete narration script — translated dialogue plus descriptions of on-screen action placed in the silences — as editable text. Stage 2 voices the approved lines and mixes them onto the video.
- POST transcript-audio-description → async job; result_data.data is the script (segments[dub|ad])
- POST transcript-audio-description-render → async job; result_data.data.video_url is the finished MP4
