Chapters

Enhance your videos with customizable chapters for improved navigation and accessibility

Overview

Chapter generation offers a simple solution for generating .vtt (WebVTT) files with desired chapter times. WebVTT (Web Video Text Tracks) is a subtitle and caption file format widely used for displaying timed text in HTML5 videos. It provides a standardized format for creating text-based content such as captions, subtitles and descriptive metadata, allowing synchronized display with audiovisual media.

In addition to generating a .vtt file, you have the option to embed chapter information directly into the video metadata. This process involves modifying the metadata tags of the video file to include the chapter markers. Embedding the chapter information ensures that the chapters remain intact even when the video is distributed or played on different platforms.

With this service, you can enhance the accessibility and user experience of your videos by providing interactive chapter navigation.

Typical use cases

This service can be valuable for a plethora of use cases, mainly:

• Improving the user experience - Adding chapter markers to your videos allows viewers to navigate through the content more efficiently. Users can quickly jump to specific sections, facilitating easier content consumption and ensuring a more engaging viewing experience, especially for longer video content.

• Enhancing accessibility - Incorporating chapter markers enables better accessibility for individuals with disabilities, such as visual impairments or cognitive challenges. Screen readers and assistive technologies can utilize the chapter information to help users navigate the video and access specific sections.

• Content organization - Chapters provide a convenient way to organize and structure video content. By generating .vtt files with desired chapter times, lengthy videos can be broken down into logical sections, making it easier for viewers to find and consume the content that is most relevant to them.

• Chapter customization - The chapter times can be defined according to specific user requirements. Customers have control over the timing and granularity of chapters, ensuring they align with the natural breakpoints or key moments within their videos.

• Content discovery - Adding chapters to recorded webinars or presentations enables participants to revisit specific segments and key points. This improves the usability of recorded events and enhances content discoverability.
