You can now dub multiple videos in one go. Upload up to 10 files, choose your settings once, and we’ll dub each video in the background.
What’s new
If you’re localizing a library of content, the old flow meant repeating the same steps video after video. Bulk Dubbing Upload turns that into one batch—so you can stay consistent and save time.
Upload a batch
- Drag and drop up to 10 videos on the Dubbing page, or select them from your computer
- See a thumbnail, upload progress, and status for each file
- Rename or remove videos before you submit
Set your dubbing settings once
- Choose your target languages
- Pick full dub with lip-sync or audio-only dub
- Set lip-sync and video timing options for the whole batch
We handle the rest per video
- Source language detection runs automatically for each file
- If detection fails for a file, you can set the source language for that video
- You’ll see one credit estimate for the full batch before you submit
