Timing and advanced editing

Let every sentence have an accurate position.

First identify audio and video, or directly import existing subtitles.
Without content, the page will not generate any sample subtitles.

Not persisted by default

Imported subtitles keep the number, sentence number and timeline by default.

Local subtitle transcription, translation and editing

ToolRobin Subtitle Studio turns audio or video into editable subtitles in the browser. You can also import SRT or VTT files, translate subtitle text, review timing against the source media and export a clean subtitle file.

Step by step

  1. Choose audio or video and run local AI transcription. Hardware acceleration is used automatically when supported, with a browser-compatible fallback when it is not.
  2. Import existing subtitles, correct wording line by line, review the media preview and export SRT or VTT after your final check.
  3. Subtitle translation changes only caption text. Subtitle numbering, start times and end times remain protected so the translated file stays aligned with the original timeline.
  4. After transcription or translation, compare caption text with the recording and keep a copy of the original subtitles. Review names, numbers and every cue’s start/end order. A successful model run does not establish accurate wording or timing.

Choosing the settings

OptionWhat changes
Edit SRT and VTTSelected media is limited to 100 MiB and 600 seconds; subtitle or project imports are limited to 2 MiB. SRT and VTT preserve timed cues, while a project JSON keeps editable project data. Export a copy before leaving the editor.
Translate without changing timecodesSubtitle translation changes only caption text. Subtitle numbering, start times and end times remain protected so the translated file stays aligned with the original timeline.
Privacy-first workflowMedia transcription runs on the device. Translation runs in the browser using built-in translation when available, with an English, Chinese and Japanese local fallback.

Example and expected result

Editing example: cue 1 starts at 1000 ms and ends at 2500 ms. Replace Hello with Hi while timing protection stays enabled. Expected: one cue lasting 1500 ms with the same number and timestamps; this demonstrates editing, not measured transcription accuracy.

If it is not working

  • The first model download needs a working connection even though your file is processed locally. If loading fails, retry the missing download; if memory is insufficient, use a smaller input. A model result still needs comparison with the original.
  • After transcription or translation, compare caption text with the recording and keep a copy of the original subtitles. Review names, numbers and every cue’s start/end order. A successful model run does not establish accurate wording or timing.
