Translate an English video into Japanese subtitles
English content in a Japanese market needs Japanese subtitles, and machine captions from the platform rarely produce them cleanly. This does it from the audio, not from YouTube's caption track.
The timing comes from the audio, so a line lands where it is actually spoken.

What happens to your video
- Upload the file or paste a public link. Phone footage (HEVC/MOV) is read as it comes off the phone.
- The audio is transcribed first, with word-level timing, so every cue starts where speech starts.
- Each line is translated on its own. Timecodes are copied through and never rewritten.
- Download the SRT, or a copy of the video with the subtitles burned in at the original resolution.
Notes on the audio
- Japanese puts the verb at the end, so a sentence can only be translated after it finishes. That is why English subtitles on Japanese video often appear slightly after the original speech.
- Politeness level changes the length of a sentence: the same acknowledgement is two to three times longer in keigo than in plain form.
- Japanese subtitles usually run one line per cue. When the English translation does not fit, break it into two cues rather than shrinking the font.

Questions
Will the Japanese lines be too long for the screen?
Lines are kept short, but Japanese usually runs longer than the English source, so a manual pass on line breaks is worth doing. Japanese subtitles usually run one line per cue. When the English translation does not fit, break it into two cues rather than shrinking the font.
Does it use YouTube's auto-captions?
No. It transcribes the audio itself, so it also works for files with no captions at all.
Can I get both languages?
Yes, bilingual output keeps the English line above the Japanese one.
