   * **Tuning**: Use the **film** option for real life scenes.
   * **Profile**: The **High** profile is OK for high-definition television (e.g. 1280×720, or Blu-ray disc), //High 10// add support for 10 bits per sample, //High 444// up to 14 bits per sample (both for [[wp>High dynamic range|HDR]] videos). Do not use //Main//, which is for standard-definition TV, e.g. 720×576.
-  * **IDC Level**: Leave this parameter to **Auto**, setting it to higer values does not increase the video quality, but imposes higher constraints to the decoder. I.e. to decode 1280×1024@42 it is sufficient the 3.1 IDC level (see [[wp>Advanced Video Coding]]).
