Compressing slide data
Captivate provides you with the option of compressing slide data that is shared between slides.
This option reduces overall file size and it is the default setting.
Note: In certain circumstances, compressed movies may not appear correctly when imported into
Macromedia Flash. If you plan to import your Captivate movie into Flash, do not select the
advanced compression option. (Not applying compression will, of course, increase the size of your
movie.)
To compress the time between slides:
Open a Captivate movie.
1.
From the Movie menu, select Preferences.
2.
Click the Preferences tab.
3.
Select Advanced movie compression.

Correcting colors in slides
In general, color should appear correctly in Captivate movies. However, there are cases in which
colors may appear inaccurately, such as when the color scheme varies radically between slides. So
if Slide A uses color palette ABC, and Slide B uses color palette XYZ, and the two palettes are
radically different, Slide B might resort to using palette ABC.
Most of these problems can be fixed by changing the video quality of the slide. Captivate provides
three levels of video quality, even though only the Standard option is suggested for most uses.
To change video quality in a slide:
Open a Captivate project.
1.
Double-click on the slide containing the colors you want to correct.
2.
From the Slide menu, select Video Quality and one of the video options:
3.
Standard: The default format for slides. Standard is the most efficient choice for the majority
of screen shots because it uses 256 optimized colors. Standard slides also compress well, which
results in smaller file sizes.
JPEG: This option is best used when the slide contains a photograph. You can change the
quality and compression ratio for JPEG images on the Movie Preferences dialog box.
High Quality: Compared to the Standard format of 256 colors, this format uses 16 million
colors for the slides. This option should only be used if the Standard and Optimized options
do not offer the correct color depth. The file size increases dramatically using this option.
Note: Selecting the JPEG or High Quality format may increase the file size and the time it takes to
download your movie. You should only use a format other than Standard when necessary and
appropriate.
