Chapter 13: Multimedia and 3D models
The possibilities for Adobe PDFs extend to the richness of multimedia communication. PDFs can include video clips,
digital audio, interactive content, and 3D models that readers can move, turn, zoom in on, and examine part by part.
Multimedia in PDFs
Play multimedia
PDFs can include many types of multimedia files, including (but not limited to) Flash®, QuickTime, mp3, MPEG, and
Windows® Media files. You can play these files on a page or activate them from a link, bookmark, form field, or page
action. Each multimedia file includes a play area from which the media can be activated. The play area typically appears
on the PDF page as an image or a rectangle, but can also be invisible.
Any computer that has Adobe Reader® can play these files.
• Media files created in Flash (FLV format)
• Media files that comply with the H.264 standard for video compression
Media files in other formats require the necessary hardware and software to play.
To help protect your computer from viruses, Acrobat asks you if you want to play multimedia files from unverified
sources. You can change this default behavior in the Multimedia Trust preferences.
❖
Using the Hand tool or the Select tool, click the play area of the video or sound file. When the pointer is positioned
over the play area, it changes to the play mode icon
