AI video translation with optional dubbing
Translate the speech, pick a voice, and download a dubbed video.
VidDub adds an AI voice in another language to your video. It transcribes and translates what is said, burns in synced subtitles, then generates a dubbed track timed to the original speaker. You can publish one video in many languages without hiring voice actors or recording again.
How AI dubbing works in VidDub
- Sign in with Google or Apple and upload your video: MP4, MOV, MKV, AVI, FLV or WebM, up to 2 GB.
- Choose the language spoken in the video and the language you want to dub into.
- VidDub transcribes and translates the speech and burns synced subtitles into the video.
- Open the dubbing step, listen to voice samples, and pick a voice.
- Generate the dubbed track and download the dubbed video.
Languages for dubbing
Translate and dub into English, Chinese, Japanese, Korean, Spanish, Brazilian Portuguese, French, German, Italian, Russian, Thai, Vietnamese, Indonesian, Arabic or Hindi. The voices on offer depend on the target language of your translation. The full list of source and target languages is on Supported languages.
Timed to the original speech
The dubbed audio is sped up or slowed down to follow the original speech timeline, so each line starts close to when the speaker said it. The burned-in subtitles stay in the video. VidDub does not clone the speaker's voice and does not change lip movements: the picture stays exactly as you filmed it.
Who uses AI dubbing
- YouTube, TikTok and Reels creators who want to reach viewers in other languages without recording again.
- Teachers and course creators who turn recorded lessons into versions for students abroad.
- Companies dubbing product demos, onboarding and training videos for teams and customers in other countries.
- Online sellers who localize product videos for new markets.
Free preview and plans
After you sign in, eligible short videos get a free preview of the translation. Optional AI dubbing is available when you export. See current plans on Credits.
Download, redub and file retention
When dubbing finishes, download the dubbed video or copy a short-lived link to it. Want a different voice? Start a redub and pick another one. Files are removed from the server after about 24 hours, so keep a copy of what you need.
Is AI dubbing free?
You can try VidDub for free: after you sign in, eligible short videos get a free preview of the translated video. Dubbing is not part of that preview. Basic dubbing is free and is not charged extra. Premium dubbing is paid in the iOS and Android apps.
Does VidDub clone my voice or sync the lips?
No. You pick a voice from the VidDub catalog. The dubbed track follows the timing of the original speech, but it is not a clone of the speaker's voice and the mouth movements in the picture are not changed.
Can I dub a YouTube video?
Yes, if the video is yours or you have the right to use it: upload the original file. VidDub does not download videos from YouTube or TikTok.
