72 Chapter 6: Pre-processing If you are authoring cross-platform movies for the Web or CD-ROM and do not want different versions for Mac OS and Windows, select a gamma setting that looks acceptable on both platforms. Usually, your movies end up looking a little light on a Mac monitor and a little dark on a Windows monitor. Although this is a compromise, it is better than having your Mac OS movies look perfect while your Windows movies are significantly darker, or having your Windows movies look perfect while your Mac OS movies are too bright. • Since you are processing your movies on Mac OS, set the gamma so it looks ideal on your Macintosh screen, then add 30 points to the gamma for a compromise. As with all settings, test your material on your target computers to determine the optimal setting. Note: There is currently no effective way to make the same video track play lighter on Windows and darker on Mac OS. However, you can create alternate versions of a QuickTime movie that have different gamma settings and are displayed according to the viewer's platform. See "Using Alternates to Adjust for Gamma Differences" on page 121 for more information. Brightness The Brightness slider makes the image lighter or darker in a linear fashion. Unlike the gamma setting, increasing the brightness changes all the pixels the same amount. Thus, your light tones tend to become totally white when you raise the brightness and your dark tones totally black when you lower the brightness. Contrast NTSC and PAL video often appear low contrast and somewhat grey when shown on computer monitors. This is due to different black levels and gamma curves. Video to be played on a computer often looks better if you slightly increase the contrast to compensate for this. You may also want to change the black level. See "Black Restore and White Restore" below for details. A Contrast setting of +20 is a good starting point. Experiment with the Contrast settings in the Adjust tab while using the Dynamic Preview to find the best setting for your movie. Increasing the brightness/gamma, in addition to boosting the contrast, may help maintain a tonal range that is similar to that of the source material when displayed on a monitor.

Since you are processing your movies on Mac OS, set the gamma so it looks ideal on your

As with all settings, test your material on your target computers to determine the optimal

Note:

There is currently no effective way to make the same video track play lighter on Windows

and darker on Mac OS. However, you can create alternate versions of a QuickTime movie that

have different gamma settings and are displayed according to the viewer’s platform. See

“Using Alternates to Adjust for Gamma Differences” on page 121 for more information.

Brightness

The Brightness slider makes the image lighter or darker in a linear fashion. Unlike the gamma

setting, increasing the brightness changes all the pixels the same amount. Thus, your light tones

tend to become totally white when you raise the brightness and your dark tones totally black

when you lower the brightness.

monitors. This is due to different black levels and gamma curves. Video to be played on a

computer often looks better if you slightly increase the contrast to compensate for this. You may

also want to change the black level. See “Black Restore and White Restore” below for details.

A Contrast setting of +20 is a good starting point. Experiment with the Contrast settings in the

Adjust tab while using the Dynamic Preview to find the best setting for your movie. Increasing

the brightness/gamma, in addition to boosting the contrast, may help maintain a tonal range

that is similar to that of the source material when displayed on a monitor.
