render in 3gp

is there a way to animate in 3gp format?
or is there any other format that is compatible with cellphones?

From my notes i found this:

ffmpeg -i clip.ogg -s qcif -vcodec h263 -acodec mp3 -ac 1 -ar 8000 -r 25 -ab 32 -y clip.3gp

It means there is an ogg-animation converted to 3gp format, so it is some command line work to do. Propably something like this is what you need to convert the clips, but I’m not quite sure about the details here.
