Generate SRT & VTT subtitles from any video
Auto-generate subtitles: upload a video or paste a link, transcribe with a timestamp-capable model, and download SRT or VTT — ready to use.
From video to subtitle file in minutes
Transcribe your video with a timestamp-capable model (most of the 6), and Silestis exports the result as SRT or VTT — the two subtitle formats video players, platforms, and editors expect. A one-hour video is transcribed in about 30 seconds; the subtitle file is one click after that.
How it works
- Upload your video (MP4, MOV, MKV, AVI, WebM) or paste a link — YouTube and 1800+ sites supported.
- Pick a timestamp-capable AI model and transcribe — each line carries its segment timing.
- Download as SRT or VTT, or export the plain text as TXT, PDF, or DOCX.
Subtitles that start accurate
- Accurate punctuation and timing — pick the highest-quality model when it matters.
- Speaker labels keep multi-speaker videos readable.
- 100+ languages with built-in translation for international audiences.
- Review before export — search the transcript and verify lines against the [mm:ss] timestamps.
SRT or VTT — which one do you need?
SRT is the most widely supported subtitle format — most video editors, players, and upload dialogs accept it. VTT (WebVTT) is the web-native format used by HTML5 video players. Silestis exports both from the same timestamped transcript, so you don't have to choose in advance.

SRT & VTT subtitles — FAQ
How do I generate an SRT file from a video?
Upload the video to Silestis or paste its link, transcribe it with a timestamp-capable model, and click the SRT export. Each subtitle line carries the timing from the transcript — no manual syncing.
Can I get VTT subtitles too?
Yes. When the transcript has timestamps, Silestis exports both SRT and VTT from the same transcript — SRT for editors and platforms, VTT for HTML5 web players.
Can I generate subtitles in another language?
Silestis transcribes in 100+ languages with built-in translation, so you can produce subtitles from content in — and for — many languages.
Do I have to upload the video?
No. If the video is online, paste its link — YouTube and 1800+ sites are supported — or use the browser extension on the page. Uploads work too, up to 10 hours on the Max plan.
