Integrating media clips into PDFs
Movie files are not physically embedded in the PDF document. Instead, you define a
rectangle within the document, and then associate a pointer with the movie file. Sound
files, unlike movie files, are physically embedded in a PDF document. You can specify how
media files play by setting options for the file.
Acrobat PDF documents will play all video and sound files that are compatible with Apple
QuickTime.
Note:
System 7 sound files and Sound Mover (FSSD) files are automatically converted to
QuickTime movies before they are played (Mac OS). This conversion may cause a slight
delay in the playback response time. With Windows, no conversion is necessary before
playing AIF or WAV files.
Adding movie clips
When you add QuickTime movie clips to a PDF document, you create a pointer to them.
Therefore, if you distribute the PDF document, you must remember to distribute the
movie files as well. Be sure to use the correct filenames and relative path locations for the
movie clips when you distribute them.
The movie image format is made up of a set number of pixels and is therefore a set size.
For this reason, it is recommended that you keep the magnification of the document page
at 100% to prevent the added movie file from being scaled inadvertently. Also, when you
click to place a movie, the pixel size of the movie frame determines the size of the
activation area. However, if you define the play area for the movie by dragging and
creating a rectangular boundary, the movie frame is enlarged or compressed to better fit
the specified area, although the movie’s original aspect ratio is always preserved. This
resizing of the movie frame to fit the custom area can result in a distorted image quality.
For this reason, clicking to place a movie is recommended over creating custom frame
sizes.
Note:
Movie files can also be played from links, bookmarks, form fields, and page actions.
