<p>The High 4:2:2 Profile <fddLink id="fdd000081">MPEG-4_AVC</fddLink> (from ITU-T H.264) supports 4:2:2 chroma at 10 bits per channel, adaptive macroblock-level switching between 8x8 and 4x4 transform block size, encoder-specified quantization scaling matrices, encoder-specified separate control of the quantization parameter for each chroma component, and monochrome sequences. The <a href="https://www.fastvdo.com/spie04/spie04-h264OverviewPaper.pdf">Overview and Introduction to the Fidelity Range Extensions</a> states that "High 4:2:2 is expected to be used frequently in studio environments."</p>
<p>NOTE: this Web page drafted prior to the amendment of the standard to add the four High profiles.<a href="../contact_format.shtml">Comments welcome</a>. </p>

<fdd:clarity>See <fddLink id="fdd000081">MPEG-4_AVC</fddLink>. Depends in part on the level and encoding algorithm selected. The High 4:2:2 Profile has the potential to produce greater clarity than <fddLink id="fdd000082">MPEG-4_AVC_BP</fddLink>, <fddLink id="fdd000083">MPEG-4_AVC_MP</fddLink>, <fddLink id="fdd000084">MPEG-4_AVC_EP</fddLink>, <fddLink id="fdd000215">MPEG-4_AVC_HP</fddLink>, and <fddLink id="fdd000216">MPEG-4_AVC_H10P</fddLink> at a given picture size and data rate. By the same token, MPEG-4_AVC_H422P clarity can be surpassed by <fddLink id="fdd000218">MPEG-4_AVC_H444P</fddLink>.</fdd:clarity>
