Create subtitle track(s)

post
https://services.uplynk.com/api/v4/assets//subtitles

Create one or more subtitle tracks for an existing asset by submitting a CloudSlicer job. This request accepts either a single subtitle input or a list of multiple tracks and associates them with the specified asset_id (which refers to the asset’s GUID). Subtitle files can be uploaded via URL or base64-encoded content, and customization options include default position, language, and track metadata.

Sample Use Cases

  • Add closed captions to a video in multiple languages.
  • Attach time-synced subtitles for accessibility or compliance.
  • Use webhooks to receive job status updates after subtitle ingestion.
