Supported video files you place in InDesign play when tapped in the viewer. For video files, use a format that is compatible with Apple iTunes, such as an MP4 file with h.264 encoding. When creating the video, use Baseline Profile for optimal compatibility with Android devices. Use .mp4 instead of .mov files, which are not supported in web viewer. If your video does not play properly in the viewer, re-encode the video to .mp4 h.264 using Adobe Media Encoder or a third-party tool such as Handbrake.
- You can play video inline or in full-screen mode.
- You can set up a video file to be played by letting users tap the view area or by creating separate buttons with the Video action. The Play, Pause, and Stop options are supported. Resume and Stop All are not supported.
- For best results with inline videos, create a movie in the appropriate dimensions, such as 400 x 300 pixels. Consider setting full-screen movies to 1024 pixels wide. The maximum video size for the HD iPad is 1920x1080, although creating a video that large increases the folio size. For a good balance between file size and quality, some publishers recommend 10-12 MB per minute of film. To reduce video size, some publishers use Adobe Media Encoder or a third-party application such as HandBrake. For details, see Keith Gilbert's article Compressing Videos for Use in DPS.
- You can specify a URL to stream video only from an http: website. To stream video using an https: website such as YouTube or Vimeo, create a Web Content overlay. In InDesign CS6 or later, you can use the Insert HTML command to insert the embed code of a YouTube clip. Make sure that the embed code includes an "http://" prefix such as src="http://www.youtube.com/..." For best results, set the overlay to Auto Play, and add a poster image on top of the overlay. For examples and instructions, see the Advanced Overlays issue of the free DPS Learn app.
- Videos stop playing when users move to a different article, but they keep playing when users move to a different page within the article. To stop the video on page turn, a workaround is to auto-play a "dummy" video. For details, see Johannes Henseler's article Stop a video when going to the next page of an article.
Select the placed object, open the Media panel (Window > Interactive > Media), and specify a poster.
For a video file, you can choose an image or specify a frame from the video. For best results, choose an image that indicates the page item is interactive. You can also create a poster image simply by placing a non-interactive object (such as a transparent play button) on top of the video object.
Select the video object and specify any of the following options in the Overlays/Folio Overlays panel.
URL or File
Specify a URL to stream a video, or click the folder and specify a video file if you haven't already placed it. When you specify a streaming URL, all options in the overlay are supported, including Auto Play and Full Screen.
Streaming a video supports http, not https. Services such as YouTube and Vimeo are not supported. Use Web Content overlays instead, as described in the "Best practices" section above.
If you both place a video and specify a streaming URL, the first action takes precedence. For example, if you specify a URL first and then place a video, the overlay uses the URL, not the embedded movie. (In fact, you can take advantage of this feature by selecting a poster for the streaming video.)
Select this option to play the video file when the page is loaded on the mobile device. You can also specify the number of seconds to delay. Auto Play is not supported for Android viewers.
Play Full Screen
If this option is selected, the video plays in full-screen mode. If this option is not selected, the video plays within its bounding area. Note that all videos on Android devices play full screen.
Tap To View Controller
If this option is selected, tapping the inline video while it’s playing displays a controller bar with pause and play controls. If this option is not selected, tapping the video pauses and restarts.
Do Not Allow Pause
If you select this option, users cannot tap the video to pause or stop it. This option is available only if Auto Play is selected and Play Full Screen is not selected.
