YouTube Video Chapters
Video chapters organize YouTube videos into sections, adding context to each part and allowing viewers to rewatch specific segments with ease.
* This module works on Joomla 3,4 and 5.
After installing the module, go to Modules > New > Youtube Chapter to start.
You need to set 2 main parameters:
- YouTube Video ID: The ID of the Youtube video. For example, if the link to the video is https://www.youtube.com/watch?v=TXNQ01Sy6Xw, then its ID is TXNQ01Sy6Xw.
- Chapters: Each line is a chapter. The structure of each chapter is <TIME><space><Chapter Caption>. <TIME> has the format "HH:MM:SS", if the video is less than 1 hour long, it has the format "MM:SS", and if the video is less than 1 minute long, it has the format "00:SS".
Examples of how to write chapters:
00:00 Introduction
01:35 Photos and videos
02:41 Entertainment
03:38 Work
04:19 FaceTime
05:26 Design
06:57 Technology
08:32 Ending

Some other parameters of the module:

1. The "radio buttons" extra field doesn't transfer the values in the additional field, e.g., "yes" or "no," and only enters certain values into the #__fields_values database.
2. The "textarea" extra field with the "Use editor" option checked converts to "textarea" when it should be "editor."
3. In K2, the extra field group is assigned in the category. In Joomla Articles, the category is assigned in the extra field. It would be nice if this were automatically completed. A checkbox could be added if someone doesn't want this option.
