Emphasis Level can be assigned any value specified in enum NV_ENC_EMPHASIS_MAP_LEVEL.
|

Emphasis Level Map is used to specify regions to be encoded at varying levels of quality.
|

The hardware encoder adjusts the quantization within the image as per the provided emphasis map,
|
||||
by adjusting the quantization parameter (QP) assigned to each macroblock. This adjustment is commonly called “Delta QP”.
|
||||
The adjustment depends on the absolute QP decided by the rate control algorithm, and is applied after the rate control has decided each macroblock’s QP.
|
||||
Since the Delta QP overrides rate control, enabling emphasis level map may violate bitrate and VBV buffersize constraints.
|
||||
Emphasis level map is useful in situations when client has a priori knowledge of the image complexity (e.g. via use of NVFBC's Classification feature) and encoding those high-complexity areas at higher quality (lower QP) is important, even at the possible cost of violating bitrate/VBV buffersize constraints
