3G Text 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
Text.
These options are available if your movie has a text track (credits, titles, subtitles, and so
on).
Some mobile devices can’t play text in a movie. To allow the movie to play only if the
text can be displayed on the receiving device, select “Require text capability on
handset.” Deselect this checkbox to allow the audio and video to play even if the text
can’t be displayed on the device.
