:{{note label|MaxBitRate|A|A}} The maximum bit rate of the profile is based on the combination of bit depth, chroma sampling, and the type of profile.<ref name=HEVCApril2014Q1005/> For bit depth the maximum bit rate increases by 1.5x for 12-bit profiles and 2x for 16-bit profiles.<ref name=HEVCApril2014Q1005/> For chroma sampling the maximum bit rate increases by 1.5x for 4:2:2 profiles and 2x for 4:4:4 profiles.<ref name=HEVCApril2014Q1005/> For the Intra profiles the maximum bit rate increases by 2x.<ref name=HEVCApril2014Q1005/>

:{{note label|MaxFrameRate|A|A}} The maximum frame rate supported by HEVC is 300 [[frames per second]] (fps).<ref name=HEVCITURecommendationH265/>

:{{note label|MaxDpbSizeMaxFrameRate|B|B}} The maximum frame rate supported by HEVC is 300 [[frames per second]] (fps).<ref name=HEVCITURecommendationH265/>
:{{note label|MaxDpbSize|C|C}} The MaxDpbSize, maximum number of pictures in the [[High Efficiency Video Coding#Decoded picture buffer|decoded picture buffer]], for the maximum luma picture size of that level is 6 for all levels.<ref name=OverviewHEVCIEEE2012/><ref name=HEVCITURecommendationH265/> The MaxDpbSize can increase to a maximum of 16 frames if the luma picture size of the video is smaller than the maximum luma picture size of that level in incremental steps of 4/3×, 2×, or 4×.<ref name=OverviewHEVCIEEE2012/><ref name=HEVCITURecommendationH265/>

:{{note label|MinCR|CD|CD}} The MinCR, minimum compression ratio, for that level.<ref name=HEVCITURecommendationH265/> The MinCR constraint is reduced to half its base value for the 4:2:2 and 4:4:4 chroma sampling profiles and is reduced by half for the Intra profiles.<ref name=HEVCApril2014Q1005/>

:{{note label|Slices|DE|DE}} The maximum number of slice segments is the number of slices allowed per picture at both the maximum resolution and maximum frame rate.<ref name=HEVCITURecommendationH265/><ref name=HEVCOctober2012K0201>{{cite news |title=AHG9: on number of slices constraint |author=Minhua Zhou |publisher=JCT-VC |url=http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=6572 |date=2012-10-01 |accessdate=2012-11-27}}</ref>

:{{note label|Tiles|EF|EF}} The maximum number of tiles allowed per picture.<ref name=HEVCITURecommendationH265/> The maximum number of tiles allowed per second is the maximum number of tiles allowed per picture times 120.<ref name=HEVCITURecommendationH265/><ref name=HEVCOctober2012K0202>{{cite news |title=AHG9: on number of tiles constraint |author=Minhua Zhou |publisher=JCT-VC |url=http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=6573 |date=2012-10-01 |accessdate=2012-11-27}}</ref>
