"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

ffmpeg -i inputfile.mp4 -vcodec h263 -b 160k -s 352x288 -acodec aac -ac 1 -ar 8000  -ab 64k -y outputfile.3gp

As for quality...that depends on the bitrate. You said you want the output video to be at 160Kbps, which is rather low, and that will only the the same quality as the source MP4 if the source file is also 160K. If the source is something like 800K, the output 3gp quality will be MUCH worse...
