Frequently asked questions

How do I dub a video?

Upload your video, trim a clip, choose its languages and click Dub video. Retwist delivers the translated speech and lip sync together as a video in Studio.

Which languages can I choose?

The language menus list the supported choices by name. You can detect the original language automatically. Choose a different target language to translate your clip.

How much does dubbing cost?

The current credit rate is shown before creation. Each started second is charged: at 23 credits per second, a 10-second clip costs 230 credits and a 10.2-second clip costs 253 credits.

Which video files can I upload?

Upload MP4, MOV or WebM up to 250 MB. Your browser prepares a 4–30 second MP4 clip under 40 MB before submission. Codec support varies by browser; use an MP4/H.264 file if preparation fails.

Will every voice and mouth match perfectly?

No. Clear speech and a visible face work best. Overlapping speakers, background noise, strong accents and hidden mouths may reduce translation or lip-sync quality.

Where can I see the result?

Open Studio to check its status and play or save the finished video. Processing time varies. A result under review should not be submitted again until its outcome is confirmed.

What happens if creation fails?

A confirmed failure returns the job’s credits. An uncertain provider response is checked before any refund or retry to avoid duplicate charges.

Are my uploads public?

No. Source clips use private signed access and are retained for 7 days. Only upload videos whose voices and likenesses you have permission to translate and modify.
