Upload audio and subtitle tracks from the dashboard

You can now add an audio or subtitle track to a media directly from the dashboard, without calling the API.

The new Upload audio & subtitles view sits alongside the read-only Tracks view in a media’s Audio & Subtitles tab. It accepts audio files (.mp3, .m4a, .wav, .aac, .ogg) and subtitle files (.srt, .vtt), either uploaded directly from your computer or, for audio, pulled from a public URL. That local-file option is the main difference from the API, which can only fetch a track from a public URL. Each track carries a title, a type that is auto-detected from the file, and a BCP 47 language name and code that label it in the player’s audio and subtitle menus.

Uploaded tracks appear in a management list where you can watch their status, and edit or delete a track. A few behaviors are worth knowing:

• Adding a track only processes that new track and leaves your existing tracks Ready.
• An audio-only media’s original audio track can’t be deleted.
• Language names can’t contain spaces, and each track needs a unique language name.
• A track that the API reports as available shows in the dashboard as a green Ready badge.
