QuickTime Help contains some incorrect information about the Advanced settings for 3G export via QuickTime Pro. This document contains corrected information.
If your file is in Mobile MP4 or EZmovie format, you can restrict distribution so that a file can't be sent or copied anywhere else once it is on a handset
With either of the two EZmovie formats, you can specify how many times the file can play on the handset once downloaded, or make the file expire after a certain number of days or on a certain date.
Note: The "Allow transfer" pop-up menu has only one option, "No transfer allowed."
With the 3GPP2 (EZmovie) format, the "Fragment movie" option is activated and hard-set to 15 second fragments. Fragmenting 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).
