When you use Local export to export a video file from Descript, subtitle tracks are embedded into the file by default. This allows services that support embedded subtitles to give viewers the option to enable or disable the subtitle text.

If you have captions in your composition, this can lead to duplicated or doubled captions in your export.

Web players often display the embedded subtitles from your exported composition during playback, but these will only appear if subtitles are enabled in the media player. If this happens, you can disable subtitles directly from your web player.

To avoid embedding subtitles, toggle off Include subtitle track in the export settings before exporting your video.

We share more information about the local exports and share page functions on our Export and publishing overview help page.
