encoding .3GP. Need help. Urgently.

[navand]

My boss thinks I'm some tech guru just because I know after effects, premiere and some programming.

Thing is, there's a few videos that need to be encoded to 3GP. Each video has to be encoded into 6 different .3gp's:

• Sound: [Stereo, AAC, 24Khz]
  Video: [QCIF(176X144)], h263
• Sound: [MPEG-4 AAC, Stereo (8kbps-80kbps bitrate and 16khz-32khz sampling rate)]
  Video: [QVGA(320X240), up to 30fps framerate and 64kbps bitrate], h263
• Sound: [AMR, Mono (8kbps-80kbps bitrate and 8khz-16khz sampling rate)]
  Video: [QVGA(320X240), up to 30fps framerate and 64kbps bitrate], h263
• Sound: [AMR, Mono, 8Khz]
  Video: [SQCIF(128X96)], h263
• Sound: [AMR, Mono (8kbps-80kbps bitrate and 8khz-16khz sampling rate)]
  Video: [QCIF(176X144), up to 30fps framerate and 64kbps bitrate], h263
• Sound: [MPEG-4 AAC, Stereo (8kbps-80kbps bitrate and 16khz-32khz sampling rate)]
  Video: [QCIF(176X144), up to 15fps framerate and 64kbps bitrate], h264

Adobe Media Encoder doesn't let me customize my settings to this remarkably specific level. After some research I found FFmpeg. But I need help.

I am way beyond my knowledge. Borderline desperate with unreasonable expectations. I need a miracle. Please.

Just checking... this not an ffmpeg forum.
This is the ffmpegX for Mac OS X general discussion forum.

I think something like this (command line) would get you those 3GPs:

• ffmpeg -i sample.avi -f 3gp -s qcif -vcodec h263 -b 200k -ar 24000 -ac 2 -acodec libfaac -ab 64k sample1.3gp
  
• ffmpeg -i sample.avi -f 3gp -s qvga -r 30 -vcodec h263 -b 64k -ar 32000 -ac 2 -acodec libfaac -ab 80k sample2.3gp
  
• ffmpeg -i sample.avi -f 3gp -s qvga -r 30 -vcodec h263 -b 64k -ar 16000 -ac 1 -acodec libopencore_amrnb -ab 12.2k sample3.3gp
  
• ffmpeg -i sample.avi -f 3gp -s sqcif -vcodec h263 -b 200k -ar 8000 -ac 1 -acodec libopencore_amrnb -ab 12.2k sample4.3gp
  
• ffmpeg -i sample.avi -f 3gp -s qcif -r 30 -vcodec h263 -b 64k -ar 16000 -ac 1 -acodec libopencore_amrnb -ab 12.2k sample5.3gp
  
• ffmpeg -i sample.avi -f 3gp -s qcif -r 15 -vcodec libx264 -vpre slow -vpre baseline -level 3.0 -b 64k -ar 32000 -ac 1 -acodec libfaac -ab 80k -threads 0 sample6.3gp

These do require external libraries (libfaac, amr-nb, x264) that ffmpeg needs to access.
