Apple Final Cut Pro 7 - Manual (Page 1641)

Note: Your iChat window may look slightly different from the illustrations shown here,
depending on the version of Mac OS X that you are using on your computer.
As you host a video chat session using iChat Theater Preview, you can play clips or
sequences in the Timeline in the Canvas window. You can also open specific clips in the
Viewer and play them for the remote viewer. You can switch between displaying video
from the Viewer or Canvas by clicking the window you want to make active. You can also
have multiple Viewer windows open and use them to show a different clip or versions
of a clip. For example, you can open three Viewer windows, each holding a different
version of a clip, and then play each window one at a time for the remote viewer to
compare.
The frame displayed in the Viewer or Canvas appears in the remote viewer’s iChat window.
In Final Cut Pro, you can stop clips and reposition the playhead on specific frames to
discuss them. You can also have Final Cut Pro display the timecode of the current frame
in the remote iChat window to help you identify specific frames. If you wish, you can
control the volume of your video using the Audio Mixer. If you make another application
active other than Final Cut Pro, a pause overlay appears in the remote viewer’s iChat
window.
During an iChat Theater Preview session, the streaming of the Final Cut Pro video is
optimized for viewing in an iChat window. The video is streamed at a lower, optimized
frame rate, formatted to fit the iChat window. Overlays and warnings or messages, such
as alerts about dropped frames during playback, are turned off. During the session, the
external video, video playback, and audio playback commands are unavailable in
Final Cut Pro.
The actual video playback performance that the remote user sees can be affected by
several factors, including the speed of the network connection, the processing speed and
power of the host and client computers, and the processing power required to play back
video in a specific format.
