English to Japanese video translation
Translate English video to Japanese
Upload a video spoken in English. Sonilo translates it into Japanese and re-voices every line for viewers in Japan. You proofread the Japanese script before anything renders.
You pick the languages after signing up. Nothing is charged until you start the translation.
Same scene, dubbed by Sonilo. Tap a language to hear it.
You read the script before it is voiced.
Four steps from the video you already have to the same video in Japanese.
- 01
Upload your English video
An .mp4, .mov or .m4v up to 5 minutes and 400 MB. Sonilo detects the language that is spoken, so there is nothing to set. Add an .srt or .vtt per language if you already have the lines.
- 02
Pick Japanese
Choose Japanese, add more languages if you like, and decide whether lip sync renders the mouths again to match.
- 03
Proofread the Japanese script
Switch on proofreading to read the transcript and the Japanese translation line by line, and fix names, product terms and jokes before anything is voiced.
- 04
Watch, then download
Play every language in the browser. Download the translated videos and their subtitles on any paid plan.
Made for the video you already cut.
The soundtrack stays
Sonilo keeps the original background music and sound effects and replaces only the speech, with lip sync on or off.
The speaker’s own voice
Sonilo keeps the speaker’s own voice in the new language, so the translated speech sounds like the person in your video, not a stock voice. There is no voice to record or set up.
Lip sync, when you want it
On: mouths are re-rendered to match the new language. Off: your original picture stays untouched and only the voice is replaced.
You approve the words
The translation is a script you can read and correct first. A product name, a joke, a line of dialogue: fix it before it is spoken.
Your subtitles, spoken
Upload an .srt or .vtt for a language and the dub says exactly those lines, instead of a machine translation of them.
Music for the new cut
Sonilo also adds music to video. If a translated version needs its own soundtrack, add music to it in the same account.

Before you upload
What people ask before they translate their first video.
Do I have to tell Sonilo the video is in English?
No. Sonilo detects the spoken language when it transcribes your video, then translates that English transcript into Japanese. You see both before anything is voiced.
Can I put Japanese subtitles on the video?
Yes, when the dub comes back with its Japanese script: proofread it first, or upload your own .srt or .vtt. On a computer you can then style the subtitles and export a copy of the video with them burned in, set in Noto Sans JP unless you pick another font.
Can I translate Japanese video into English too?
Yes. Japanese to English is a pair of its own: upload the Japanese video and pick English as the target.
Can I translate the same English video into more languages?
Yes. Pick Japanese and as many of Sonilo's 24 dubbing languages as you need in one job, all from one upload. Each language is priced on its own.
Which languages can I translate into?
English, German, Spanish (Latin America), Spanish, Hindi, Indonesian, Arabic, French, Chinese (Mandarin), Japanese, Portuguese (Brazil), Portuguese, Vietnamese, Korean, Italian, Russian, Tamil, Turkish, Kannada, Thai, Gujarati, Malayalam, Punjabi (India), Sindhi (India). Pick any number in one job.
How long can my video be?
Up to 5 minutes and 400 MB, as .mp4, .mov or .m4v. For something longer, split it and translate the parts.
Can I edit the translation?
Yes. You read and correct the translated script before the video is rendered, so names and phrasing come out the way you want.
What does lip sync change?
With lip sync on, the speakers' mouths are rendered again to match the new language. With it off, your picture is left exactly as it was and only the voice changes, so mouths still move to the original language.
Does Sonilo keep the background music and sound effects?
Yes. Sonilo keeps your video's original background music and sound effects and replaces only the speech, so the translated version plays over the same soundtrack, with lip sync on or off.
Does Sonilo clone the speaker's voice?
Yes. Sonilo keeps the speaker's own voice in the new language: the translated speech sounds like the person in your video, not a stock voice, and when several people speak, each keeps their own. There is no voice to record or set up first.
I already have subtitles. Can I use them?
Yes. Upload an .srt or .vtt for a language and the dub says exactly those lines.
How does Sonilo compare with HeyGen, ElevenLabs and Rask?
Sonilo suits short creator clips that also need music or sound effects: 24 languages, videos up to 5 minutes, lip sync on Pro and Premium, plus one free trial on Free and Creator. HeyGen lists more languages, and ElevenLabs Dubbing is the cheapest way in. We make Sonilo, and our comparison of eight AI video translators, limits included, is at https://sonilo.com/compare/best-ai-video-translators.
Can I translate a video for free?
The free plan comes with 2,000 credits every two weeks, which covers about 40 seconds of video in one language. You can watch the result in the browser. Downloading it takes any paid plan.
