 ~~~~~~~~~~~~~~~~~~~~
 
 :option:`--tune` *grain* tries to improve the retention of film grain in
-the reconstructed output. It helps rate distortion optimizations select
-modes which preserve high frequency noise:
+the reconstructed output. It disables rate distortion optimizations in
+quantization, and increases the default psy-rd.

 It lowers the strength of adaptive quantization, so residual energy can
 be more evenly distributed across the (noisy) picture:
