Why SRT and VTT export matter
Caption files often need to travel separately from the video. You may need SRT for a platform upload, VTT for a web player, and a captioned MP4 for social sharing.
The useful workflow is to clean the captions once, then export the format each destination needs.
- Use SRT for broad platform and editor compatibility.
- Use VTT for browser video players and web learning platforms.
- Use captioned MP4 when subtitles must be permanently visible.
Why editing comes before exporting
A file conversion can change syntax, but it cannot verify whether captions match the speech. Captn keeps video preview, text cleanup, timing controls and export formats together so the final SRT or VTT is useful.
You can import existing SRT/VTT files, generate captions from video, fix the subtitle layer, and download the reviewed result.
