| Platform | Use | Note |
|---|---|---|
| MP4 | Publishing and editor exports | A practical choice when the final delivery file is already an MP4. |
| MOV or M4V | Camera and Apple-oriented workflows | Upload the exported file directly instead of creating a separate audio copy. |
| WEBM | Browser and web recordings | Useful for browser captures and recordings exported from web tools. |
| MKV | Recorder and archive files | Check that the intended dialogue track is audible before transcription. |
Export guide
| Format | Best for | Note |
|---|---|---|
| SRTRecommended | Editors, players, and common video platforms | Numbered cues with start and end timestamps. |
| VTT | HTML5 and browser-based video players | A web-oriented timed-caption format. |
| TXT or DOCX | Editorial review and copy reuse | Use when you need readable text rather than a timed subtitle track. |
Working from audio only?
Video is not required for subtitle generation. If your source is an audio-only MP3, use the MP3 to SRT converter to create timed captions before attaching them to a video edit or player.
