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).
