SRT Generator is the subtitle-export workflow for creators who need an editable `.srt` file. Add media from your device, transcribe it with browser Whisper, inspect timing, and download an SRT draft for your editor or caption-review process.

What you can export:

  • .srt file with numbered cue blocks
  • SRT draft with millisecond timestamps
  • VTT alternative exported from the same result

Best for:

  • editable SRT drafts
  • timestamp review
  • video editing workflows

Privacy: Whisper transcription runs in the browser-first workflow. Media stays on your device instead of going through an upload-first dashboard.

Before you export: Start with a short representative clip, then check names, numbers, technical terms, and important cue boundaries against the source. A transcript or subtitle file is an editable machine-generated draft, not a legal record, translation, speaker-identification result, or proof of accessibility compliance. Keep your source file, make corrections before publishing, and use only material you are permitted to transcribe. Keep a short correction log with the final export so later edits remain traceable.

How It Works

1

Add audio or video

Use the media that already sits in your edit.

2

Generate the timed draft

Browser Whisper produces cues with start and end times.

3

Nudge the cue boundaries

Align each cue with the spoken phrase in your timeline.

4

Download the .srt

Import the file into the editor or upload it to the platform.

Features

Numbered Cue Blocks

Output follows the SRT structure editors expect: index, timestamp line, caption text.

Millisecond Timestamps

Cue boundaries you can nudge against the edit timeline.

Editor Import

Bring the draft into a desktop NLE or a web player without conversion.

Format Swap

Export VTT from the same transcript when the destination needs WebVTT instead.

Use SRT Timing as an Editable Draft

An SRT file pairs numbered caption cues with start and end timestamps. Generate the draft, play the source alongside it, and correct cue boundaries, reading speed, spelling, and punctuation before delivery. Prefer word-level alignment only when the extra model download and processing time are worthwhile for the project.

The generator does not translate captions, burn text into a video, or certify accessibility compliance. If your destination needs another format, export VTT or TXT from the same transcription result and adapt it in the platform or editor you use.

SRT Structure and Editor Handoff

SRT is a small, strict format: a cue index, a comma-separated millisecond timestamp line, the caption text, and one blank line before the next cue. Small deviations break importers — a missing blank line, a period instead of a comma in the milliseconds, or Windows line endings where the editor expects something else. If a downloaded file is rejected, inspect the first two cues before assuming the transcription was wrong.

The draft is designed for a handoff, not for final delivery. Editors differ in how they treat overlapping cues, styling tags, and frame-rate ambiguity, so import the file, check the first and last minute, and confirm the timeline interpretation matches the project frame rate. Keep the reviewed .srt beside the source media so the export can be rebuilt without re-transcribing.

SRT Generator — FAQ

How do I create SRT file output?

Use the SRT file generator to transcribe the media you select, inspect the timing, and create SRT file output you can edit in a video workflow.

Can I use audio to SRT and video to SRT?

Yes. The same SRT file generator handles audio to SRT and video to SRT exports when the browser can read the selected file.

What is inside an SRT file?

Numbered cue blocks: an index, a start and end timestamp in the form HH:MM:SS,mmm, then the caption text, with a blank line before the next cue.

Can I edit the SRT after download?

Yes. It is plain text, so any editor can change the text or timings as long as the file stays UTF-8 and keeps the blank line between cues.

Does this translate subtitles?

No. It transcribes the spoken language it hears; translation is a separate step you perform after reviewing the source-language draft.

Can I get word-level timing instead of segments?

Precise subtitles mode adds word-level alignment. It needs an extra model download and more processing, so use it when a project needs tighter sync.
