You can make your long form videos easier to watch and navigate by adding chapter markers to single videos or to Adaptive Video Sets. When a user plays the video, they can click the chapter markers on the video timeline (also known as the video scrubber) to easily navigate to their point of interest, or immediately jump to new new content, demonstrations, tutorials, and so on.
The video player that is used must support the use of chapter markers.
See Adding or editing a video viewer preset to configure the chapter navigation cue points and chapter title pop-up text for the Universal_HTML5_Video viewer (HTML5).
See also Adding and editing Viewer Presets.
If desired, you can create and brand your own custom video viewer with chapters instead of using a video viewer preset. For instructions on creating your own HTML5 viewer with chapter navigation, in the Adobe Scene7 Viewer SDK for HTML5 guide, in the Adobe Scene7 Viewer SDK, reference the heading “Customizing Behavior Using Modifiers” under the classes s7sdk.video.VideoPlayer and s7sdk.video.VideoScrubber.
The Adobe Scene7 Viewer SDK is available as a download from the following location:
You create a chapter list for your video in much the same way that you create captions. That is, you create a WebVTT file. Note, however, that this file must be separate from any WebVTT caption file that you may also be using; you cannot combine captions and chapters into one WebVTT file.
You can use the following sample as an example of the format you use to create a WebVTT file with chapter navigation:
WEBVTT Chapter 1 00:00.000 --> 01:04.364 The bicycle store behind it all. Chapter 2 01:04.364 --> 02:00.944 Creative Cloud. Chapter 3 02:00.944 --> 03:02.937 Ease of management for a working solution. Chapter 4 03:02.937 --> 03:35.000 Cost-efficient access to rapidly evolving technology.
In the example above, Chapter 1 is the cue identifier and is optional. The cue time of 00:00:000 --> 01:04:364 specifies the start time and end time of the chapter, in 00:00:000 format. That last three digits are milliseconds and can be left as 000, if preferred. The chapter title of The bicycle store behind it all is the actual description of the chapter’s contents. The cue identifier, the starting cue time, and the chapter title all appear in a pop-up in the video player when a user hovers their mouse pointer over a visual cue point in the video’s timeline.
Because you are using an HTML5 video viewer, ensure that the chapter file you create follows the WebVTT (Web Video Text Tracks) standard. The chapter filename extension is .vtt. You can learn more information about the WebVTT captioning standard.
To add chapter markers to video
Save the .vtt file in UTF8 encoding to avoid problems with character rendition in the chapter title text.
Generally, you want to name the chapter VTT file the same name as the video file, and append it with chapters. By doing so, it can help you with automating the generation of the video URLs using your existing web content management system.
In the Viewer List table, find the HTML5 viewer named Univeral_HTML5_Video, and then do one of the following:
For a pop-up video viewer experience, click Copy URL to the far right of the name.
Append the copied URL of the video with the following syntax to associate it with the copied URL to your caption file:
&navigation=<full Copy URL path to the chapter navigation file .vtt>
For an embedded video viewer experience, click Embed Code to the far right of the name.
In the Embed Code dialog box, click Copy to Clipboard.
For the HTML5 Universal_HTML5_Video viewer, append the copied embed code with the following:
videoViewer.setParam("navigation","<full Copy URL path to the chapter navigation file .vtt>”
