What’s new

If you’ve ever shipped a localized video and then realized it needs captions, you know the drill: export an SRT, open another tool, and burn captions in manually.

Now, you can do it directly during dubbing:

  • Turn on Burned-in captions when creating a dub (it’s off by default)
  • Captions appear in the dubbed language and are timed to the dubbed audio
  • Each language version keeps its own setting, even if you edit the transcript and retranslate

This helps your dubbed videos work better in more places:

  • Sound-off viewing (social feeds, autoplay in LMS, internal comms)
  • Accessibility, without extra steps

What to know

  • Caption sharpness depends on your original upload quality. For crisp captions, upload 720p or higher
  • Captions use a fixed style (the same style as our existing burned-in captions), and Styled Captions aren’t supported for dubbing yet

For more on how it works, check out our documentation.
