      Modified no memory rate control. · eec3def7

      This 2-pass rate control setting allocates bits based
      on first pass stats to each kf group, gf group and individual
      frame but does not correct the bits left and allocation after
      each frame.
      
      In other words it recommends a bit allocation for each frame
      but does not try and correct any over or under spend on a
      frame over the remainder of the clip. This reduces the accuracy
      of rate control in terms of hitting an average bitrate but prevents
      problems that may arise because early frames either use to many
      or too few bits. This mode is currently more inclined to undershoot
      than overshoot (particularly at higher data rates).
      
      Also minor changes to rate of adaption when recode loop is not
      enabled.
      
      This mode is currently enabled by default for VBR.
      It gives the following % performance gains.
      
      derf +0.467, +1.072
      yt 2.962, 2.645
      stdhd 1.682, 1.595,
      yt-hd 2.3, 2.174
