Working With Files 153
Note: The Movie Box doesn’t record
cursors, so you don’t have to worry about
getting a “hand” in the shot.
Playing Back QuickTime Movies
You can use the QuickTime movie player
to play back your movies. If you have
QuickTime Pro, you can also use it to edit
your movies. To play back a movie,
double-click the file in the folder where
you saved it. Starry Night does not need to
be open when you play back the movie.
Movie Compression Settings
If you have ever tried to download a video
file from the Internet, you know how large
these files can be. The same thing can
happen with QuickTime movies because
they are also composed of a series of still
images. If you are using 30 frames per
second (the standard rate for television
images), this means 900 images for a 30
second video! It is easy to understand how
even a short movie can easily be a few
megabytes in size. The compression
settings dialog box offers different ways to
keep your movie files down to a
manageable size. This window will open
automatically the first time you make a
movie.
Compressor: This popup lets you
choose from several different
compression formats. “Sorenson Video
3” is a good all-purpose compression
format. Depending on the compression
format chosen, a second popup menu
may allow you to choose from several
colour options.
Quality: The slider lets you adjust the
quality of the recording. The better the
quality, the larger the file size.
Motion: Within this box you can adjust
how many frames per second are
displayed when the movie is played
back and how often to draw a key
frame, and limit the amount of data
stored per second to a maximum value.
