About Creating A Video File For Use In Other Software - Adobe PREMIERE 5 User Manual

316 CHAPTER 11
Producing Final Video
MPEG
Motion Picture Experts Group (MPEG) is a file format that compresses video files effectively
but is not as standardized as QuickTime or AVI. There are actually several variations
of MPEG. The version generally used for Internet and CD-ROM is MPEG-1, which provides
picture quality nearly comparable to VHS. MPEG-2 can provide SVHS picture quality.
However, the keyframe-based compression that makes MPEG popular for delivery of final
video makes it unsuitable for high-quality editing. MPEG export is not built into Premiere,
but Premiere-compatible plug-in modules are available from other companies or may be
included in some video-card bundles.
Streaming video
Streaming video resembles conventional television in that video is sent to you frame-by-frame,
without downloading a large file to your hard drive. Streaming video export is not built into
Premiere, but Premiere-compatible plug-in modules are available from other companies or
may be included in some video-card bundles. Streaming video on the Web is constrained by
the limited bandwidth (56 Kbps or less) of most consumer modems. However, streaming video
can be deployed effectively within intranets where high-speed bandwidth is more
readily available.
About creating a video file for use in other software
Premiere exports to many formats readable by other applications. For example, you can export
a QuickTime movie for use in Adobe After Effects. When preparing to export to a video file for
use in other video-editing or special effects software, answer the following questions:
What file formats and compression methods does the other software import? This helps
•
determine which format you will use to export.
Will you be transferring across computer platforms? This may constrain the choice of file
•
formats and compression methods further. Consider using high-quality cross-platform codecs
(transcoders) such as QuickTime Motion JPEG A or B, or the Animation codec.
Will you be superimposing the Premiere clips over other clips? If so, preserve alpha channel
•
transparency when exporting from Premiere.
