Convertin any video format to 3gp format

[subchief]

Guys i need help converting videos to 3gp format.

i have installed transmaggedon software but it fails to convert because quicktime muxer plugin is not installed.

This plugin is not available in the repositories.

How can i get this video converter to work or what else can i do to be able to convert videos to 3gp format?

Thank u!!!

The 3gp container can hold a quite limited range of codecs, see here for some details. The most compatible pair of codecs would be h263 for the video and amr for the sound, although quality for both of these is never great. A sample commandline for this combination, using FFmpeg, is as follows:

ffmpeg -i <input_file> \
       -s qcif -vcodec h263 \
       -acodec libopencore_amrnb -ac 1 -ar 8000 -r 25 -ab 12200 \
       <output_file>

This will be ok on an older mobile phone for example but newer devices will support aac sound which will make a huge improvement to playback. Lots of room for experimentation there with the device you wish to use for playback and the codecs available to you .

Can't you convert it in OpenShot? Import the file, add it to the timeline, then export it as .3gp and the correct audio codec in the Advanced tab.
