How to export SRT or VTT subtitles
Create a transcript with timing, review the segments, then export the subtitle format your video editor or player accepts.
Start with a source you may process
Upload a supported audio or video file, paste a supported link, or start from a supported Safari page. Choose a mode that supplies timestamps if you need subtitles synchronized to the original recording. A plain transcript without usable timing is not equivalent to synchronized captions.
Check words and timing
Review names, numbers and specialist vocabulary against the audio. Check the start and end of the recording and several points in the middle for alignment. Transcription errors and poorly timed segments should be corrected before publication; an export is not a guarantee of broadcast or accessibility compliance.
Choose the format your destination supports
- SRT is a common interchange format for video editors: numbered cues with start and end times.
- WebVTT uses a WEBVTT header and is commonly used for captions in web players.
- TXT contains the transcript text and is useful for reading or editing, but is not a timed subtitle file.
- Silestis provides TXT, SRT and VTT exports on Free; other formats and AI features depend on the plan.
Test the exported file in the destination
Illustrative example: export the subtitles for a short tutorial, import the file into your video editor, then replay a passage near the beginning and one near the end. If captions drift, investigate the timing or any edits made to the media. Renaming a file from .txt to .srt does not create valid subtitle timing.
When you trim or rearrange the source video, check the subtitle timing again. Keep a copy of the reviewed transcript so you can correct the captions without repeating transcription unnecessarily.

FAQ
Should I choose SRT or VTT?
Use the format your destination accepts. SRT is widely used by video editors; WebVTT is common for captions in web players.
Can Free users export subtitles?
Free includes TXT, SRT and VTT export within its transcription and credit allowances. Usable source timing still depends on the selected mode.
Are exported subtitles ready to publish without review?
No. Check transcription accuracy, synchronization and your destination requirements before publishing.
Start from the supported lecture page you already use.
