Subtitle Generator makes timed subtitles from the speech in a video or audio file. Each line gets its start and end time, ready for YouTube, VLC, Premiere, DaVinci Resolve or CapCut. The video is processed in your browser, so it is never uploaded.
How to make subtitles
- Choose the video (MP4, MOV, WebM, MKV) or its audio file. Only the sound is used.
- Choose the language: English (fast) for clear English, English (more accurate) for accents or noise, or the spoken language.
- Click Transcribe. Lines appear as they are recognised.
- Correct the text in the box, keep Subtitles (.srt) under Download as and download.
How the timings are made
The speech is cut at natural pauses, and every piece becomes one subtitle with its own start and end time. Silence between sentences is skipped, so subtitles disappear when nobody is talking. A long stretch of speech without a pause is split into pieces of at most about 20 to 30 seconds.
A downloaded SRT looks like this:
12
00:01:04,200 --> 00:01:07,900
And that is why we start with the basics.Editing before you download
Fix names, technical terms and punctuation directly in the box. Keep one line per subtitle: as long as the number of lines stays the same, every line keeps its timing. If you join or split lines, the timings no longer match, so make those changes in your video editor afterwards.
Adding the subtitles to a video
| Where | How |
|---|---|
| YouTube | YouTube Studio > Subtitles > your video > Add language > Upload file, with timing |
| VLC | Put the .srt next to the video with the same name, or Subtitle > Add Subtitle File |
| Premiere Pro, DaVinci Resolve | Import the .srt and drag it onto the timeline as a caption track |
| CapCut and other editors | Use the import captions or subtitles option |
| Instagram, TikTok, WhatsApp, anywhere | Burn them into the picture with Add Subtitles to Video, so they always show |
Tips
- Clear speech with little music gives the best subtitles. For a noisy video, run the sound through Noise Reduction first and transcribe the cleaned file.
- Long lines are hard to read on screen. Shorten the wording where you can; the timing stays.
- For a plain transcript instead, switch Download as to Text. No need to transcribe again.
