How to add subtitles to a video

Gaston can turn any transcript into a ready-to-use SRT subtitle file, timed and split into lines automatically, no manual timestamping required.

1. Open your file's menu

Log in and find the file you want subtitles for in your library. Click the three-dot menu on its card.

2. Choose Export

Open the "Export" panel from the menu, it lists every format Gaston can generate from the transcript.

3. Pick SRT

Select the SRT format and pick the language, the original transcript or any translation you've already generated for it. The file downloads immediately, ready to drop into a video editor or upload alongside your video.

4. Exporting a lot of files? Do it in bulk

Select multiple files in your library and use bulk export to generate SRT subtitles for all of them at once, packaged into a single download.

Free accounts can export files up to 30 minutes long; PRO removes that limit entirely.

Need the subtitles in another language first? Translate the transcript with the guide below, then export the translated version as SRT the same way.
