 Use this mode to retain good visual quality and do not care about the exact bitrate or filesize of the encoded file.
-  * The mode works exactly the same as in x264, except that maximum value is always 51, even with 10-bit support, so please read the H.264 guide for more info.

   * **-tune**:  Choose a tune (optional).
     * By default, this is disabled, and it is generally not required to set a tune option.
