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
