 Codec : H.264 or MPEG-2 . If set to Any , the codec is automatically
detected: this value is suitable when you do not want to use this
parameter as a criterion to select the video stream.

Note: this parameter allows to allocate the system resources (CPU,
memory, license) to the job.
 Clock management : if set to Convert to device internal clock
(default value), then the input clock is converted to the device clock. If
set to
Keep input clock , then the input clock is kept. When you want to
multiplex components from different input programs, the clocks shall
be converted to the device clock. When you want to output a
pass-through component that is scrambled, or that contains private
sections that contain some clock values, you shall keep the input clock
for the whole program.
 Generate fake component on absence : set it to true if you want
to create of fake component on absence of input component.

When no video is detected at the extractor input then a fake video
component is declared in the PMT with the configured information:
 Fake Program Number
 Fake PMT PID
 Fake Component PID
 Fake Codec
When a real video is detected then the fake component is removed. 
Even if Program number or Video PID are configured to All only
one fake component is created in the output PMT.

This mechanism can be used to generate a Dash MPD if there is no
stream at the input of the job.
If
Maximum format is set to HD 1080p@60 fps or UHD
2160p@25/30/50/60 fps, color dynamic range parameters are displayed.
You can select a dynamic range between
SDR , HDR-HDR10 ,
HDR-PQ10 , HDR-HLG and depending of the Dynamic range you
must configure the corresponding parameters:
 If dynamic range is set to SDR, define the color space.
 If dynamic range is set to HDR-PQ10 or HDR-HDR10 , define the
Display primaries , White point position , Maximum and
Minimum display mastering luminance , Maximum content
and Maximum frame average light levels .
 If dynamic range is set to HDR-HLG , define the HLG signaling .
The following parameters can be set to
Auto : Color space , Display
primaries
, White point position, Max and Min display mastering
luminance
, Max content light level , Max frame average light
level
. 
If it is the case, their values are extracted from the input stream if
available.
