Video Translator: Translate a Video and Dub It
This video translator turns a video into another language and gives you the video back, dubbed. Only its sound uploads: read the translation line by line next to what was said, give each speaker a native voice or their own, dub it, and the new sound goes back into your video in your browser, the picture copied as it is. Subtitles and the bilingual text come with every translation.

How do you translate a video?
To translate a video, drop it into the video translator, choose the language to translate into and press Translate. Only the sound uploads. Read each line next to the original, then dub it: the dub goes back into your video in your browser and you download the video, in the same format, with subtitles if you want them.
Translate video in three steps
The translation arrives as text first, so you read every line before a word of it is spoken.
Drop in your video
An MP4, MOV, MKV or WEBM file. Your browser takes out its sound and only that uploads; the video stays on your device. Dubs run up to 60 minutes.
Read the translation line by line
Every line shows what was said and its translation, with who said it and when. Correct a name, rename the speakers, or download the subtitles straight away.
Dub it and get your video back
Give each speaker a voice and dub. The new sound goes into your video in your browser, the picture copied as it is, and you download the translated video.
Why use this video translator
Your video comes back as it was, in a new language, with the translation checked before anything is spoken.
Video translation that leaves your video on your device
Every video translation tool we tested takes your whole video and makes a new one on its servers. Here only the sound goes up, about 1 to 2 MB a minute. When the dub is ready, your browser puts it back into your own file and copies the picture as it is: the same frames, size and frame rate, and the same format you brought.
Each speaker in their own voice, or a native one
This AI video translator tells speakers apart and hears each one for their voice, so a man and a woman get different voices that sound like them. Switch on “Keep their own voice” and each translated line is turned into that speaker’s voice from the video, or pick any voice from the library.
Check the video translation before it is dubbed
The translation comes back line by line next to the original, with the speaker and the time. Fix a name or a number, and when you change a line after dubbing, only that line is dubbed again, its credits shown on the button.
Video dubbing on the speakers’ timing, lip-sync when you want
Each translated line is written to fit the time its original line took and placed where it was said, so the dub follows the speakers on screen. A line that would run long is marked before you dub. By default the picture stays as it is, mouths included; the optional lip-sync moves them to the new words.
Music and background sound stay
When music or the sound of the place plays under the speech, it is separated from the voices and kept under the dub, so the video still sounds like where it was made.
Subtitles and the translation, ready to use
Every translation gives SRT and VTT subtitles timed to the video, and a bilingual DOCX and TXT. Use the subtitles on their own for a video translation without a dub, or upload them with the dubbed video.
Video translator samples
Each sample is one of our own videos, translated and dubbed by this video translator and put back into the video by the studio: the dub exactly as it came out. Switch between the original and the translated video at the same moment, and read both languages line by line.
Video translation, step by step
Which videos an AI video translator handles best
Clear speech, one person at a time, gives the cleanest translation: lessons, interviews, product videos, tutorials, vlogs and talks. A crowd talking over itself is the hardest case.
By default the picture is not changed, which suits videos where the speaker’s mouth is small on screen, off screen or in a voice-over. For a close-up, the optional lip-sync moves the mouth to the dubbed words, for videos up to 3 minutes, at 2 credits a second counted in five-second steps for each part, a part within 0.1 s of a step counting as the next (the button shows the total first). The video’s parts are uploaded for it and the picture is encoded again at 30 fps. A 15-second clip usually takes about 6 minutes; longer videos run four parts at once, so 3 minutes takes about half an hour, longer when the model is busy.
Translate video to English
Leave the language heard on Auto, choose English as the language to translate into, and press Translate. Translating takes 2 credits a minute, plus 1 credit for each started 10 minutes.
Check names and numbers in the English, then dub it in a native English voice or in each speaker’s own voice.
Check the video translation before you dub
A quick read turns a good translation into one you can publish. Work in this order and it goes fast.
- 1Rename the speakers, so every line shows who says it.
- 2Check names, places and numbers, clicking a line’s time to hear it.
- 3Say any line marked as too long in fewer words.
- 4Move a line given to the wrong speaker.
Get the translated video back
In Chrome and Edge on a computer, the video translator gives back an MP4 or MOV with the dub, and WEBM and MKV come back as video in Chrome, Edge and Firefox. Firefox can’t write the sound an MP4 or MOV carries, so there you get the dub on its own as MP3; open the run in Chrome or Edge to get the video. The new sound track is marked with the dub’s language, so players list it by its language.
Videos up to 1 GB (300 MB on a phone) come back as video. For a bigger file, download the dub and the subtitles and put them under the video in a desktop editor.
Opened a translation later? Drop the same video again and the dub goes back into it. The video’s length is checked, and nothing is charged again.
Translate video subtitles only
You don’t have to dub. Every translation already gives SRT and VTT subtitles in the new language, timed to the video, which most players and video sites take as a caption file.
