How to dub a video
Dubbing is mostly about preparing a clip with clean speech, then choosing how closely the picture should follow the new language.
- 01
Upload a video with clear speech
The video needs a spoken track to translate, so a silent clip is rejected. Clear speech with little background music gives the translation the best material to work from.
- 02
Choose languages and options
Pick up to the allowed number of target languages. Turn lip sync on to match the mouth movement to the new audio, or off if you only want the voice to change.
- 03
Confirm the cost and collect the results
You see the credits per language before anything runs. Each language is a separate result, and you can download a subtitle file alongside the dubbed video.
What the dubbing tool handles
Translation and voice in one step
The speech is transcribed, translated and re-voiced for you, so you do not manage separate transcription, translation and recording tools.
Lip sync as an option
With lip sync on, the mouth movement is matched to the new audio. With it off, only the voice changes and the picture stays exactly as filmed.
Natural pacing
Adaptive speed lets the pacing flex so the translation sounds natural, which can leave the dubbed video slightly longer or shorter than the original.
Speaker handling
Automatic speaker detection works for most videos, and you can set the number of speakers when a dub blends different people into one voice.
Who dubs a video, and why
Creators reaching new audiences
Publish the same video for viewers in other countries without refilming it or relying on subtitles they may skip.
Ads and product videos
Run one proven creative in several markets and compare results, changing only the language.
Training and explainer videos
Give a team in another country the same walkthrough in their own language.
Course and webinar content
Localise recorded lessons so more learners can follow along comfortably.
Short-form clips
Turn a high-performing clip into several language versions for different regional accounts.
What makes a dub feel natural, and what to check before you publish
In VerseIn you upload one video with clear speech and choose the target languages, up to the allowed number, in a single run. The speech is transcribed, translated and re-voiced, and you decide whether lip sync should match the mouth to the new audio. The credits per language are shown before anything runs, each language comes back as its own result, and a subtitle file can be downloaded alongside the dubbed video.
A translation is rarely the same length as the original. Many languages need more or fewer syllables to say the same thing, which is why a dub that forces the new speech into the old timing sounds rushed or oddly slow. Letting the pacing adapt avoids that, at the cost of a clip that may run a little longer or shorter than the source. For most uses that is the right trade.
Lip sync decides how much of the picture the tool is allowed to touch. With it on, mouth movement is adjusted to the new language, which helps when the speaker is close to the camera and the viewer will notice a mismatch. With it off, the video is left alone and only the voice is replaced, which is safer for wide shots, voice-over style clips and footage where faces are small or turned away.
The input decides most of the quality. Speech recorded in a quiet room, with one person speaking at a time, translates and voices much more cleanly than a crowded scene with music running over it. If your source has loud background music, a cleaner version of the audio will improve the result more than any setting.
Always have someone who speaks the target language listen to the result before it goes out. Names, brand terms, numbers and jokes are where machine translation is most likely to drift, and a short review is far cheaper than a corrected re-upload. The subtitle file you can download is a convenient way to read through the translation first.
Finally, think about the whole package. A dubbed video still carries the original on-screen text, so decide whether titles and captions need localising as well. Handled together, a single source video becomes a set of finished regional versions.
AI video dubbing FAQ
What does a video need to be dubbed?
It needs spoken audio to translate, a supported format, and to be within the length and file-size limits shown on the upload step. A video with no sound is rejected.
Can I dub into more than one language at once?
Yes, up to the maximum shown in the tool. Each language is charged and delivered separately, and the confirmation step shows the total before you commit.
Should I turn lip sync on?
Turn it on for close-ups where a viewer would notice a mouth that does not match. Leave it off if you want the picture untouched and only the voice replaced.
Will the dubbed video be the same length?
Not always. Adaptive speed lets the pacing flex so the translation sounds natural, so the result can be slightly longer or shorter than the original.
Can I get subtitles too?
Yes, a subtitle file can be downloaded for the dubbed result, which is also a handy way to proofread the translation.
What does it cost?
It uses the same credits as the other tools, charged per language. The estimate is shown before you confirm, and a language that fails is refunded.
