Manage audio and subtitle tracks

Add tracks to a video from the dashboard

Add audio and subtitle tracks to an existing media from the FastPix dashboard by uploading a file or an audio URL, with no API call required.

You can add audio and subtitle tracks to an existing media directly from the FastPix dashboard, without calling the API. Use it to add a dubbed audio track or a caption file to a video you’ve already uploaded. Unlike the API, which fetches a track from a public URL, the dashboard also lets you upload a file directly from your computer.

To add tracks programmatically instead, see Add audio to a video and Add subtitles to a video.


Before you begin

  • A FastPix account with an active workspace (Activate your account).
  • An existing media in your dashboard.
  • An audio or subtitle file on your computer, or a public URL to an audio file.

Supported formats

  • Audio: .mp3, .m4a, .wav, .aac, .ogg
  • Subtitles: .srt, .vtt

Add an audio or subtitle track

  1. In the dashboard, open the media and, under Manage Media in the left navigation, select Audio & Subtitles. Then open the Upload audio & subtitles sub-tab.
  2. Add the track in one of the following ways:
    • Upload a file: drag and drop an audio or subtitle file into the upload area, or click Browse to select it.
    • Add audio from a URL: paste an audio file URL into Upload using audio URL, and then click Upload. This option is for audio tracks only.
  3. In the dialog, set the following details, and then click Start upload media:
    • Media Title: a label for the track.
    • Type: set automatically based on the file, either Audio or Subtitle.
    • Language Name: the label shown in the player’s audio or subtitle menu, such as English. Don’t include spaces, and give each track a unique language name. For example, after you add a track named English, you can’t reuse English for another track.
    • Language Code: a BCP 47 language tag, such as en, es, or fr.
  4. The track appears in the Uploaded audio and subtitles list with the status Preparing. When it changes to Ready, the track is available in the player: audio tracks appear in the audio menu, and subtitle tracks appear in the CC menu.

Manage uploaded tracks

Use the Action column in the Uploaded audio and subtitles list to edit a track’s title, language name, or language code, or to delete it. To review the tracks already attached to the media, open the Tracks sub-tab in the Audio & Subtitles tab.

NOTE:

  • Don’t leave or refresh the tab while a file is still uploading, because that cancels the upload.
  • Adding a track only processes the new track you’re adding. Your existing tracks stay Ready, and the media itself isn’t re-processed.
  • For an audio-only media, the original audio track can’t be deleted.
  • If you also use the API, a finished track reports its status as available, which the dashboard shows as a green Ready badge.
