To find a decent bitrate simply multiply the target pixel count by the frame rate; then multiply the result by a factor of 1, 2 or 4, depending on the amount of motion in the video; and then multiply that result by 0.07 to get the bit rate in bps. While you may believe that a higher bitrate will result in better video quality, this is not always the case. So, bitrate is a unit of measurement that comes under bandwidth.
