You can add movies and sound clips to a document, or you can link to streaming video files on the Internet. Although media clips cannot be played directly in the InDesign layout, they can be played when you export the document to Adobe PDF or when you export the document to XML and repurpose the tags.
A poster is the image that represents a media clip. Each movie or sound can appear with or without a poster. If the poster in InDesign is larger than the movie, the poster is clipped to the size of the movie in the exported PDF document.
QuickTime 6.0 or later is required to work with movies in InDesign. You can add QuickTime, AVI, MPEG, and SWF movies, and you can add WAV, AIF, and AU sound clips. InDesign supports only 8‑ or 16‑bit WAV files that are not compressed.
Keep track of the media files you add to an InDesign document during the production cycle. If you move a linked media clip after adding it to the document, use the Links panel to relink it. If you send the InDesign document to another person, include any media files you add.
You may want an object to link to a web URL that plays a streaming media file. After you export the document to Adobe PDF or to a different format, clicking the object plays the movie, if an Internet connection is available.
You can edit movie options by double-clicking the movie play area using the Selection tool, or by selecting the movie object and choosing Object > Interactive > Movie Options.
You can edit sound options by double-clicking the sound play area using the Selection tool, or by selecting the sound object and choosing Object > Interactive > Sound Options.
You cannot simply use a placed image as a poster. Instead, specify any of the following types of poster images in the Movie Options or Sound Options dialog box:
