+The parameter 'q' which is displayed while encoding is the current
 quantizer. The value 1 indicates that a very good quality could
 be achieved. The value 31 indicates the worst quality. If q=31 appears
 too often, it means that the encoder cannot compress enough to meet
 your bitrate. You must either increase the bitrate, decrease the
 frame rate or decrease the frame size.

+If your computer is not fast enough, you can speed up the
 compression at the expense of the compression ratio. You can use
 '-me zero' to speed up motion estimation, and '-intra' to disable
 motion estimation completely (you have only I-frames, which means it
 is about as good as JPEG compression).

 uses the same quality factor in the encoder as in the decoder.
 It allows almost lossless encoding.
