CHAPTER 11 314
Producing Final Video
About creating a video file for the Internet
In general, Internet video is constrained by delivery data rates that are even lower than those
used for CD-ROM playback. Use the guidelines for CD-ROM exporting (see ““About creating
a video file for CD-ROM playback” on page 313”), but tune them to the data rates available on
the networks through which you expect to deliver the video.
You have many choices for delivering video over the Internet. Each method has specific
capabilities and workflow requirements, so consider the choices carefully.
Animated GIF, GIF Sequence, and GIF
Animated GIF is best suited for solid-color motion graphics at a small frame size, such as an
animated company logo. It is convenient because it is viewable in most Web browsers without
requiring a plug-in. You cannot include audio in an animated GIF file. Animated GIF works
better for synthetic graphics than for live-action video. Don’t confuse Animated GIF with the
GIF Sequence file type, which is a series of individual single-frame GIF files, or GIF, which is
one still image in one file. You export animated GIF the same way you do any other file, making
sure that you choose Animated GIF as the File Type. See “Exporting video files” on page 304.
For best results, test completed Animated GIF files in a Web browser before distributing.
When you choose File > Export movie, click Settings, choose Animated GIF or GIF Sequence
for the File Type, and click Advanced Settings, the following options are available:
Dithering
Select to simulate colors that are not available in the Web-safe color palette used by
Web browsers. Dithering simulates unavailable colors using patterns that intersperse pixels
from available colors. Dithered colors may look coarse and grainy, but dithering generally
improves the apparent color range and the appearance of gradations. Deselect this option to
move unavailable colors to the next closest color in the palette; this may cause abrupt color
transitions.
Transparency
Select None from the menu to create the movie in an opaque rectangle. Select
Hard to convert one color into a transparent area; click Color to specify the color. Select Soft to
convert one color into a transparent area and soften the edges; click Color to specify the color.
