You can add, update, or delete subtitle tracks directly from any asset in the Uplynk platform. Subtitle tracks allow you to deliver content in multiple languages, and fine-tune how they appear on screen. Whether you’re localizing content or enhancing the viewer experience with aligned positioning, subtitles can be easily managed through a streamlined UI on each asset.


Adding Subtitles

To add subtitles to an asset:

  1. Go to the asset detail page.
  2. Click the Subtitles tab.
  3. Click the + Subtitle button.
  4. Fill in the Add subtitles form:
FieldRequiredDescription
DescriptionThe name of the subtitle track. For example, “English CC” or “Spanish.”
LanguageThe ISO 639 language code, typically 2–3 characters (e.g., en, es, fra).
Absolute TimeOptionalEnable this to align subtitles with the start of the video. Disable it to keep the timing from the original file.
HorizontalOptionalDefault horizontal alignment for subtitles only if the file doesn’t include positioning. Options may include Left, Center, or Right.
VerticalOptionalDefault vertical alignment for subtitles only if the file doesn’t include positioning. Options may include Top, Middle, or Bottom.
Subtitle FileUpload your .srt, .vtt, or .ttml. You can drag and drop the file, or click Browse Files.

Click Create to upload the track. Once added, the subtitle appears as a new row in the subtitle table for that asset.


Editing Subtitles

To edit an existing subtitle track:

  1. Go to the Subtitles tab on the asset page.
  2. Click the row for the subtitle you want to edit. This opens the edit modal.
  3. The same form will appear, with your current values filled in.
  4. Some fields—like file upload and alignment settings—may be locked unless you upload a new file.
  5. Click Update to save your changes.

Deleting Subtitles

To delete a subtitle track:

  1. Go to the Subtitles tab on the asset page.
  2. Find the subtitle row you want to remove.
  3. Click the trash icon in that row.
  4. Confirm the deletion.

This removes the subtitle from the asset. It does not delete the original file from your media storage.
