Will you be superimposing the clips over other clips? If so, preserve alpha channel
transparency
when exporting from Adobe Premiere Pro.

What is the highest quality compression method that the other software imports?
Using high-quality compression limits the degree of compression that can be applied
to the video file while retaining quality. You want to retain the highest possible level of

picture quality until the editing process is complete. For maximum quality, choose the
None compressor (no compression) if you have sufficient disk space to store the very
large file that will result.

Do you want to paint on frames? If so, you can export to Filmstrip format and edit in
Adobe Photoshop (see “Exporting a filmstrip file for editing in Adobe Photoshop” on
page 301). Alternatively, you can export frames as a numbered sequence of individual
still-image files, and edit each file in Photoshop.

Do you want to use a single frame as a still image? If so, see “Exporting a filmstrip file for
editing in Adobe Photoshop” on page 301.
About creating Internet media
For dial-up modem users, Internet video is constrained by delivery data rates that are even
lower than those used for CD-ROM playback. Match the data rates of your exported video
to the networks through which you expect to deliver the video. The Adobe Media Encoder
contains presets for many bandwidth scenarios so that you can more easily match the
viewing capabilities of your audience.
You have many choices for delivering video over the Internet. Each method has specific
capabilities and workflow requirements, so consider the choices carefully.
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 on the Web is
constrained by the limited bandwidth (56 Kbps or less) of most consumer modems. Use a
higher bitrate if you know your audience has broadband Internet access, such as DSL or
cable modem service. Streaming video can be deployed effectively within intranets where
high-speed bandwidth is more readily available.
The following streaming video formats are available for export from Adobe Premiere Pro:
QuickTime, Windows Media, and RealMedia. You can create streaming video using any of
the options in the Adobe Media Encoder.
Progressive downloadable video
A progressive download movie (also called a
hinted
movie) can begin playing before it is
completely downloaded. The movie player (for example, QuickTime, MediaPlayer, or
RealPlayer) begins playback when it calculates that the movie will be fully downloaded by
the time playback reaches the end of the video. You can create progressive downloadable
video using the Adobe Media Encoder.
MPEG video
MPEG (Motion Picture Experts Group) is a file format that compresses video files
effectively.
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; a form of MPEG-2 is part of the definition for DVD video.
However, the keyframe-based compression and variable bitrate that make MPEG popular
