(The frame rate or the bit rate?) Is this reproducible with ffmpeg (the application)? To test if it is at all possible to reach a given bitrate for a given input file, you can use a high constant quantizer to test: $ ffmpeg -i input -qscale 31 -vcodec h263 out.avi I don't think 22k for qcif and h263 is realistic. If you really meant frame rate than you can choose it freely assuming the container allows it.
