52 Chapter 4 Exporting Files With QuickTime Pro

3G Streaming Options

When you export a movie to 3G format (by choosing File > Export and then choosing

“Movie to 3G”), you access the following options by clicking Options and then clicking

Streaming.

To create a file for RTSP streaming to QuickTime Player, select “Enable streaming.” This

option creates a hint track (instructions necessary for streaming a file).

“Optimize for server” helps the server to process the file faster, but increases the file

size.

3G Advanced Options

When you export a movie to 3G format (by choosing File > Export and then choosing

“Movie to 3G”), you access the following options by clicking Options and then clicking

Advanced.

If your file is in Mobile MP4 or EZmovie format, you can restrict distribution so that

once the file is on a handset it can’t be sent or copied anywhere else. You can specify

how many times the file can play back on the handset once downloaded, or make the

file expire after a certain number of days or on a certain date.

“Fragment movie” enables the file to download via HTTP in small pieces so that

playback can start faster and so that larger files can be played on the handset (only the

fragment, not the entire movie, must fit on the handset at one time).
