Chapter 8. Working with Visual Tracks

Chapter 8. Working with Visual Tracks

Several QuickTime track types—video, sprite, 3D, text, MPEG, and Flash—have visual components. Also, streaming tracks often contain visual data.

In this chapter, we’ll cover QuickTime Player functions that apply to all these types of visual tracks. These functions allow you to change a track’s size, shape, and location; make portions transparent or translucent so that you can see other tracks layered below; and alter the colors used to display them. You’ll find many of these techniques to be most useful when you’ve combined tracks (by using the Add or Add Scaled commands, covered in Chapter 7). You may discover, however, that some are helpful even if your movie contains only one visual track.

We’ll also go over what you need to know if you want to add visual data to a QuickTime VR movie or a custom color table to any movie.

We’ll cover the process of exporting QuickTime visual tracks as still-image or animation files in other formats.

Finally, we’ll cover a new feature in QuickTime 5: media skins, which allow you to create yet another kind of track, called a skin track.

To find out more about visual tracks, make sure to read Chapters 9, 10, and 11, which cover individual track types.
