MPEG-4 Streaming Export Options
When you export a movie to MPEG-4 format (by choosing File > Export and then
choosing “Movie to MPEG-4”), you access the following options by clicking Options and
then clicking Streaming.
If you’re going to deliver the exported file using RTSP streaming, select “Enable
streaming.”
Streamed data must be sent in smaller-size packets. Some networks have limitations on
packet size and packet duration. If your network provider gives you information about
size limitations, you can change the packet size and the maximum packet duration to
comply with your delivery network. Otherwise, use the default values.
