H.265 HEVC Encoder
The H.265 HEVC encoder processing component is able to encode
H.265 HEVC video in 4:2:0, 8/10 bits, from low resolution up to UHD.
Figure 3-287. H.265 HEVC encoder parameters
For this processing component, you must set the following parameters:
 Rate mode : indicate if the component bitrate should be CBR , Capped
VBR or Statmux . If set to Capped VBR , indicate the characteristics of
the video component, as shown hereafter.
It is not possible to use values outside of the bitrate range, and it is not
recommended to reduce the bitrate range.

Min bitrate : indicate the minimum ES bitrate that the video
component should have.
 Max bitrate : indicate the maximum ES bitrate that the video
component should have.
 Rate Control Quality : set the picture quality level required, in
percentage. The value must be between 10 and 90% (best
quality). Default value: 70%.
 Bitrate : (CBR only) enter the bit rate value (without encapsulation
overhead), in bits per second.
When the input video is chunked, an IDR frame is set at the beginning
of the chunk. This overrides the configuration parameters.
If you set the minimum bitrate to a lower value than the minimum
value of the range, the value applied is the minimum value on the
range, and inversely for the maximum bitrate.
