About
Order machine or professional captions for one or more media entries using REACH.
Captions are provided in the same language as the media. If you need translated captions or subtitles in another language, see Ordering Translations.
You can also create rules to automatically request captions, OCR, chaptering, or dubbing for new entries that meet specific criteria. For more information, see Create captioning & enrichment rules in Rich Media CMS.
If Content Lab is enabled on your account, you may also see a Captions & Translations option when ordering captions. For instructions using this workflow, see Order captions in Rich Media CMS with Content Lab.

Machine captions
Machine captions (ASR) provide an average accuracy rate of approximately 85%.
Machine captions support:

Professional captions:
