Documentation

When a video includes subtitle tracks (embedded in the HLS manifest), the player displays a subtitle button in the control bar for quick toggle, and a selector in the settings panel to choose between available languages. Subtitles can be enabled by default, auto-started on load, and the preferred language can be configured via embed parameters. A notification popup briefly confirms which track has been activated.

The subtitle button in the control bar toggles subtitles on and off.
The subtitle selector in the settings panel lets you choose a language.

Frequently asked questions

Which subtitle formats does the player accept?

The player consumes WebVTT tracks multiplexed in the HLS manifest (<code>EXT-X-MEDIA TYPE=SUBTITLES</code>). If you upload SRT files to Videas, they are converted to WebVTT automatically before packaging, so you don't need to convert them yourself.

Can subtitles start automatically in the viewer's language?

Yes. Add <code>subtitles=1</code> to enable them on load, and <code>subtitle_lang=fr</code> (for example) to select a specific language. Without <code>subtitle_lang</code>, the player falls back to the browser's <code>Accept-Language</code> preference.

Are subtitles indexed for SEO?

Videas exposes the full transcript and subtitle text on the public video page (when enabled), making every spoken word searchable by Google. For private embeds, subtitles remain available inside the player but are not published on external SERPs.
