5 To reduce the file size of a QuickTime movie at the expense of quality, select an option from
the Compressor pop-up menu. Different options appear on the Compressor pop-up menu
depending on the video hardware and software available in your system. Consult your
QuickTime documentation.
Animation compression is for simple animations.
Cinepak compresses 16-bit and 24-bit video for playback from CD-ROMs.
Component Video is usually used when capturing from a live video feed.
Graphics compression is for exporting single frames of computer graphics.
None exports with no compression.
Photo-JPEG compression is good for scanned or digitized continuous-tone still images.
Video compression is for exporting video clips.
6 To determine the compression quality and resulting file size when using the chosen
compressor, use the Quality slider. A higher-quality setting preserves the appearance of the
images and motion but increases the size of the file. A lower-quality setting results in poorer
image quality but decreases the size of the file.
7 To determine the color depth (the number of colors) of your artwork, select a setting from the
Color Depth pop-up menu. The compression method you select determines the color depth
options available to you in this pop-up menu.
8 To determine the method by which the exported QuickTime movie is resized, select values for
Scale. You can select a percentage from the Scale pop-up menu, or you can type pixel
dimensions in the fields. By entering the number of pixels, you can stretch a movie so that it
plays in a rectangle that does not adhere to the original aspect ratio.
9 To choose which soundtracks are exported with your movie, select Channel 1 or Channel 2. A
checked box indicates that the associated sound channel in the score is exported with your
QuickTime file.
External sounds (sounds you imported as linked cast members) are not exported when you
export a digital video. To include sound when you export a digital video movie, you must
import the sounds as cast members instead of linking to them.
Looped sounds don’t loop in a movie that you have exported as a digital video. To loop a sound
in a movie that you plan to export as a digital video, you must trigger the sound by alternating
it between the two sound channels.
