178 Chapter 10: Working with Video
• If you are comfortable with ActionScript, you can write custom ActionScript to control video
playback. You can play or stop a video, jump to a frame, and control video in other ways. You
can also display a live video stream from a camera. For more information, see “About
controlling video playback using the Timeline” on page 192.
Note: You can preview frames of an imported video by dragging the playhead along the Timeline.
However, the sound does not play back. To preview the video with sound, use the Test
Movie command.
You can use the Property inspector and the Embedded Video Properties dialog box to modify
embedded and linked video clips. The Property inspector lets you give the clip an instance name;
change the width, height, and registration points; and swap a video clip with another video clip.
The Embedded Video Properties dialog box lets you rename a video clip, update an imported
video that you have edited in an external application, or import another video to replace the
selected clip. For more information, see “Changing the properties of a video clip” on page 190.
For lessons on working with video, see Import and Edit Video on the Macromedia Flash Support
Center at www.macromedia.com/support/flash/images_video/flash_video/.
