6.8 Audio and Video Metadata<br />
<strong>Amazon</strong> requires that publishers (or their conversion houses) provide a description of the audio and video<br />
file, and the duration of the file in minutes and seconds, in the HTML immediately after the audio and<br />
video file is specified.<br />
Example:<br />
<br />
<br />
<br />
“There is video content at this location that is not currently supported for your<br />
device. The caption for this content is displayed below.”<br />

6.9 NCX File<br />
When creating eBooks with audio and video content, <strong>Amazon</strong> requires the creation of an NCX file that<br />
points to the audio and video assets. This file should list all video and audio files in reading order, with<br />
links to where they occur in the book. For descriptions of the audio and video files, reuse the same audio<br />
and video metadata. (Example: A link to the video clip in section 6.8 would say “How to create Kindle<br />
content (5:01)”.) This information should be embedded in the NavList portion of the NCX file.<br />
6.10 Images with Play Controls<br />
It is possible to tag images so that they can be played by clicking on them. The minimum pixel width and<br />
height for such images is 45 pixels by 45 pixels.<br />
To add play controls to the image, superimpose the <strong>Amazon</strong> PLAY icon onto the lower right-hand side of<br />
any image via Photoshop or similar program. Then add the following tag to the HTML (in this example,<br />
the audio file has an id attribute of “audio1” and no controls tag):<br />
Example:<br />
<br />
However, if you are using KindleGen version 1.2 or earlier, use the following HTML instead:<br />
