Why creators use AI Dubbing & Translation in MCV Labs
Timed to the original
Each translated segment is placed on the original timeline so it lines up with your video.
Subtitles included
Every dub comes with SRT files for the source and the translation, ready for your video editor.
Charged only on success
If a dub fails, you are not charged. The cost depends on the length of the recording and the text translated.
Works with your editor
For video, you receive a new audio track and subtitles to drop into your existing edit — your video is not re-rendered.

Frequently asked questions
How does AI dubbing work?
Your recording is transcribed with segment timings, each segment is translated, spoken by the AI voice you chose, and placed back on the original timeline.
How long can my recording be?
It depends on your plan: up to 60 seconds per file on the free plan and longer on paid plans (up to 20 minutes on Pro and Business). Files can be up to 25 MB.
Does it replace the audio in my video?
It gives you a new translated voice track and subtitle files. You combine them with your video in your editor; MCV Labs does not re-render the video.
Will the dub sound like the original speaker?
No. The translation is spoken by the AI voice you choose, not a copy of the original speaker's voice.
