$ man ffmpeg
       ·   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.

       ·   To have a constant quality (but a variable bitrate), use the option '-qscale n' when 'n' is between 1 (excellent quality) and 31 (worst
           quality).

       ·   When converting video files, you can use the '-sameq' option which uses the same quality factor in the encoder as in the decoder.  It
           allows almost lossless encoding.
