Codecs with names containing media formats MUST support those 526formats. 527 528If device implementations support video codecs: 529 530* [C-2-1] All video codecs MUST publish achievable frame rate data for the 531following sizes if supported by the codec: 532 533<table> 534 <tr> 535 <th></th> 536 <th>SD (low quality)</th> 537 <th>SD (high quality)</th> 538 <th>HD 720p</th> 539 <th>HD 1080p</th> 540 <th>UHD</th> 541 </tr> 542 <tr> 543 <th>Video resolution</th> 544 <td><ul> 545 <li class="table_list">176 x 144 px (H263, MPEG2, MPEG4)</li> 546 <li class="table_list">352 x 288 px (MPEG4 encoder, H263, MPEG2)</li> 547 <li class="table_list">320 x 180 px (VP8, VP8)</li> 548 <li class="table_list">320 x 240 px (other)</li></ul> 549 </td> 550 <td><ul> 551 <li class="table_list">704 x 576 px (H263)</li> 552 <li class="table_list">640 x 360 px (VP8, VP9)</li> 553 <li class="table_list">640 x 480 px (MPEG4 encoder)</li> 554 <li class="table_list">720 x 480 px (other)</li></ul> 555 </td> 556 <td><ul> 557 <li class="table_list">1408 x 1152 px (H263)</li> 558 <li class="table_list">1280 x 720 px (other)</li></ul> 559 </td> 560 <td>1920 x 1080 px (other than MPEG4)</td> 561 <td>3840 x 2160 px (HEVC, VP9)</td> 562 </tr> 563</table> 564 565* [C-2-2] Video codecs that are characterized as hardware accelerated MUST 566publish performance points information.
