日本語 Japanese captions, in kanji and kana or Romaji

Muvomi hears Japanese in a video, with the English words people mix into it, and writes the captions the way you choose: in kanji and kana, with no spaces between words, in Latin letters (Romaji), or translated into English or 50 other languages. In kanji and kana or Latin letters every word keeps its time; a translation is timed phrase by phrase.

How Japanese captions work

Everything auto captions do
  1. Put the video in the editor

    Import a video or a recording with Japanese speech in it, and open Captions.

  2. Press Auto-caption

    Language starts on Auto, which takes the language from the voice; or choose Japanese first. The captions are laid on the timeline, each word at the moment it is said, and the tool says what it heard.

  3. Choose how it is written

    Write in: Latin letters (Romaji), kanji and kana, or Translate to English and any other language of the list. The captions change at once.

  4. Pick a look and export

    Choose one of the caption looks, then export the video with the captions in it, or download the SRT or VTT file.

Japanese captions, questions answered

Last updated .

Can Muvomi make Japanese captions from a video automatically?

Yes. Put the video in the editor, open Captions and press Auto-caption. Language starts on Auto, which takes the language from the voice, so Japanese speech is written as captions in kanji and kana, each word at the moment it is said, and the tool says what it heard: “Heard Japanese: Japanese in kanji and kana.” You can also choose Japanese in the Language list first; it is told to the recognizer when it listens.

How do I get Japanese captions in Latin letters?

Choose Japanese in Language, then Write in: Latin letters (Romaji). Each Japanese word is written in Latin letters as Romaji writes it, and English words stay as they were said. Nothing is listened to again, and every word keeps its time.

Can the captions be in kanji and kana?

Yes. Choose Write in: kanji and kana. The words are written as they were heard, with no spaces between Japanese words, as Japanese is written, and every word keeps its own time for the looks that follow the voice. All 87 caption looks draw kanji and kana.

Can it translate Japanese speech into English or another language?

Yes. Choose Write in: Translate to English, and pick the language in Translate to: English first, then 50 others. The speech is translated phrase by phrase, and each phrase is shown while it is said.

Can I ask the editor's AI for Japanese captions?

Yes. Ask it in your own words: “Japanese captions”, “captions in Romaji” or “translate the captions to English”. It sets the choice and writes the captions already made again, without listening again. “Japanese captions” on a voice that speaks another language translates them into Japanese.

Can I download Japanese subtitles as SRT or VTT?

Yes. The Captions panel downloads SRT and VTT files, which carry the captions as they are written: in kanji and kana, in Latin letters or translated.

Does changing the language or the writing cost anything?

Listening to a recording is a captions job, 10 credits, once. Writing the words in Latin letters or translating them is a captions job the first time each is asked for; going back to a writing already made, and choosing English, cost nothing and listen to nothing again. Choosing a language other than the one heard offers Listen again as that language, which is one more captions job.
