[FFmpeg-user] video quality problem with ffmpeg command mov to 3gp

[aris sirajawali]

how to convert video from mp4 to 3gp using ffmpeg.
I use a command like the following: ffmpeg-i INPUT.MOV-acodec libfaac-ab
12.2k-ac 2-ar 8000-vcodec h263-s QCIF-r 10-b 32k OUTPUT.3GP
but by using the above command, I get the video that is not good.

whether there is an error on my order and how do i get the command line with
the results of a good video.

thank you, please help from friends all..
