What is WebVTT?
WebVTT, or Web Video Text Tracks, is a popular standard for displaying subtitles or closed captions in HTML5 video players. Developed with human readability in mind, it allows for placing text cues on a timeline relevant to the video content.
You can think of the commands in a WebVTT file as guides, providing precise instructions about when and how a text should appear on the screen. Its versatile nature means it can seamlessly handle subtitles and chapter titles, descriptions, and navigation menus, making it an increasingly robust and essential tool in online video content.
WebVTT vs. SRT
Subtitles or captions are critical to enhancing the user experience in video content. WebVTT and SRT (SubRip Subtitle) are two prevalent formats to create these displays. While they share many similarities, their differences lie in their capabilities and features.
SRT is primarily designed to display subtitles mapped with respective time codes. On the other hand, WebVTT was derived from SRT but went a step further in offering additional features. WebVTT provides precise subtitles/captions and allows you to tweak the positioning and alignment of the text on the screen, making it more flexible.
You can also include metadata in the files, making it exceptionally useful for providing descriptions, chapter titles, and navigation cues. While SRT may provide simplicity for basic captioning needs, WebVTT offers the robustness needed for enhanced interactive features.
When is WebVTT Used?
WebVTT’s functionalities reach far and wide, offering developers a significant range of possibilities beyond ensuring subtitles sync with the video. Here are some common situations where you might encounter WebVTT:
- Subtitling and captions: WebVTT synchronizes accurate text cues—subtitles or captions—with video playback, enhancing viewer understanding and accessibility.
- Chapter titles: For videos with multiple distinct sections or ‘chapters,’ WebVTT presents timely, well-curated chapter titles.

- Multilingual Support: With the internet’s global reach, subtitles aren’t limited to just one language. WebVTT provides excellent support for multilingual subtitles, making it easier to share content across language barriers.
- Metadata: WebVTT goes beyond the visual and includes a method to add valuable metadata to your content—this could pertain to information about the film or video, the creative team, or other essential details that aren’t displayed visually.
- Video SEO: By including captions, descriptions, and metadata, WebVTT naturally enhances Video SEO. Search engines can index the provided text, making your videos more discoverable and boosting their ranking in search results.
WebVTT, with its numerous features and ease of implementation, bolsters the viewer experience while ensuring your content achieves widespread accessibility and higher discovery rates.
