Movies and sound clips you add to a document can be played when the document is exported to Adobe PDF or SWF, or when you export the document to XML and repurpose the tags.
You can import video files in Flash Video format (.FLV and .F4V), H.264-encoded files (such as MP4), and SWF files. You can import audio files in MP3 format. Media file types such as QuickTime (.MOV), AVI, and MPEG are supported in exported interactive PDF files but not in exported SWF or FLA files. We recommend that you use file formats such as FLV, F4V, SWF, MP4, and MP3 to take full advantage of the rich media support offered in Acrobat 9, Adobe Reader 9, and Adobe Flash Player 10 or later.
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.
