Original video stays local
For supported formats, the browser prepares audio locally and uploads the prepared audio rather than the complete video stream.
VIDEO SUBTITLE WORKFLOW
Create an SRT subtitle file from video.
Media2Text prepares the video’s audio track in your browser, transcribes the speech, keeps timing for review and exports corrected cues as SRT.
Upload video for SRT →What this workflow gives you
Review with timing
Search the transcript and replay important moments before turning the text into subtitle cues.
Export for the next tool
Download SRT for broad compatibility or VTT for a web-video workflow after checking cue readability.
How it works
- Choose a supported video. Upload MP4, MOV, MKV, WebM, WMV, MPG, TS or 3GP that contains an audible track.
- Transcribe the prepared audio. Select the spoken language and speaker option, then review the timestamped transcript.
- Preview and export SRT. Set cue length and duration, check the result and download the subtitle file.
Subtitles need more than accurate words
A useful subtitle must be correct, synchronized and readable. Even when the transcript words are accurate, automatic cue boundaries may need adjustment around pauses, sentence structure, speaker changes and quick edits.
Transcription covers spoken audio. It does not describe silent action or automatically capture every title card. Accessibility work may require separately authored descriptions and a review of meaningful on-screen text.
The original video remains on the device during supported browser-side audio preparation. Prepared audio is still uploaded for transcription and follows the published retention policy, so review privacy requirements before processing confidential footage.

Questions and limits
Which video formats can be turned into SRT?
Supported inputs include MP4, MOV, MKV, WebM, WMV, MPG, TS and 3GP when the file has a playable audio track.
Is the complete video uploaded?
For supported browser workflows, Media2Text prepares audio locally and uploads the prepared audio required for transcription, not the original video.
Can it subtitle a silent video?
No. Speech transcription requires audible speech; silent visual action needs separately written captions or descriptions.
Can I export VTT instead?
Yes. Choose VTT when a web player or platform requests WebVTT rather than SRT.
