Steps

  1. Confirm the target file extension (.srt or .vtt) is in Document Translation's supported format list, since caption formats are handled as a first-class document type distinct from plain text
  2. Upload the subtitle file to a source Blob Storage container and configure a SAS-signed source/target container pair as with any Document Translation batch job
  3. POST a batch translation request specifying the target language(s); Document Translation parses cue blocks and translates only the caption text, leaving timecodes and cue numbering untouched
  4. Poll the batch and document status endpoints until translation completes, then download the translated .srt/.vtt from the target container
  5. Spot-check translated captions for line-length/reading-speed issues, since MT output length can differ substantially from the source and may need re-timing or line-splitting for on-screen readability
