How it works

From the cut to a subtitle file.

The soundtrack is read out of the video for you.

1

Add the video

MP4, MOV or WebM into the box above, or paste a public link. Anything over 500 MB continues on the upload page.

2

Check the cues

Each word is timed against the audio and the cues are built from those times. Your first transcript opens in full at any length.

3

Export SRT or VTT

SRT for editors and platform uploads, VTT for web players, and TXT, DOCX, MD and JSON from the same job.

The character budget

Japanese subtitles are counted, not word-wrapped.

The timing comes out of the job. Fitting the characters is the editorial work that follows.

About 16 characters a line

Japanese subtitle practice commonly allows roughly 16 full-width characters per line and two lines per cue — a far tighter budget than the same scene in English.

Reading speed in characters

Around four characters a second is a widely used ceiling for adult programming. A dense line that is technically on screen long enough can still be unreadable, so trim rather than hold.

No spaces, so breaks are choices

Japanese does not separate words with spaces, which means a line break falls wherever you decide a phrase ends. The file gives you timings; the break is an editorial judgement.

Full-width punctuation and UTF-8

、 and 。 and the full-width ? need the file imported and saved as UTF-8, or the cues arrive in the editor as mojibake.

Sidecar or burned in

Two ways the subtitles reach the viewer.

What you download is the sidecar file; burning in happens in your editor.

A file beside the video

SRT or VTT stays separate: the viewer can switch it off, a platform can read the words, and a correction does not mean re-exporting.

Rendered into the frame

For subtitles that cannot be turned off, import the SRT into Premiere Pro or DaVinci Resolve and set the typeface and position there.

Speaker labels are not in the file

SRT and VTT carry words and timings only. If a scene needs the speaker named on screen, add it in the editor — JSON is where the speaker of each segment is kept.

Trim, do not shrink

When a line will not fit the budget, cut words rather than reduce the type size. Subtitles that shrink stop being readable on a phone.

FAQ

Japanese video subtitles, answered.

Do the Japanese subtitles come back in Japanese?

Yes, in Japanese script rather than romaji. Nothing is turned into English: Japanese video produces Japanese cues, and that is the file you download.

How many characters fit in a Japanese subtitle line?

Common practice is around 16 full-width characters per line and two lines per cue, at roughly four characters a second. The file gives you the timing; fitting the characters is an editing decision.

How are the cues timed?

Every word carries its own timestamp and the cues are built from those, so a line appears when it is spoken rather than on an even split of the running time.

Will the subtitle file say who is speaking?

No. Numbered speaker labels appear in the transcript view on screen. SRT and VTT hold words and timings; JSON is the export that keeps the speaker of each segment.

Why do my subtitles show as garbled characters in my editor?

That is almost always an encoding mismatch. Import and save the file as UTF-8 and the kanji, kana and full-width punctuation come through intact.

Can I paste a link instead of uploading?

Public video links are usually fetched and transcribed. Some sources refuse to hand over audio, Spotify, Podbean and Kick VODs among them, and for those upload the file.

How long can the video be?

Up to 10 hours or 5 GB per file. The box here takes 500 MB, and your first transcript reads in full at any length.
