# 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:

1. Open a Captivate movie.

2. Double-click on the slide containing the colors you want to correct.

3. From the Slide menu, select Video Quality and one of the video options:

   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.
