Parameter Values Description
Profile for 3G input Profile Off,
HDp50/59.94 HEVC Main Profile Level 4.1 High Tier 4:2:0 8 bit,
HDp50/59.94 HEVC Main Profile Level 4.1 High Tier 4:2:0 10 bit,
HDp50/59.94 HEVC Main Profile Level 4.1 High Tier 4:2:2 8 bit,
HDp50/59.94 HEVC Main Profile Level 4.1 High Tier 4:2:2 10 bit
The profile to set when a 3G input is
detected on the SDI input. Visible only if
Input Detection is set to Auto Detect
and Configure. If this option is visible,
the Video Profile cannot be set
manually.
Profile for UHD input Profile Off,
UHD HEVC Main 10 Profile Level 5.1 High Tier 4:2:0 10 bit,
UHD HEVC Main 10 Profile Level 5.1 High Tier 4:2:2 10 bit
The profile to set when an UHD input is
detected on the SDI inputs. Visible only
if Input Detection is set to Auto Detect
and Configure. If this option is visible,
the Video Profile cannot be set
manually.
Resolution 1280 x 720, 1920 x 1080, 3840 x 2160
Defines the horizontal and vertical
resolution of the encoded video. The
available options depend on the values
set for Video Input Format and Video
Profile.
Signalling Options
SDR (BT.709), UHD SDR (BT.2020), HDR HLG10 (HDR in VUI),
HDR HLG10 (SDR in VUI), HDR PQ10
The HDR signalling option to be used.
Video Bit Rate The valid bit rate range depends on the selected video profile.
Defines the bit rate to be used by the
compressed video component. If Bit
Rate Tracking Mode is set to Maximize
Video for the Transport Stream that
contains the video component, and the
Bit Rate Weighting of the component is
set to other than Fixed or Minimal, this
field is read only.
Buffer Mode CBR Constant Bit Rate operation.
Low Delay
Reduced encode delay achieved by
removing pre-processing functions. Bit
Rate, GOP structure and GOP length
impact the delay. The IP GOP structure
will give low delay, but with reduced
quality.
Mega Low Delay
Encode delay reduced further by
removing frame-sync in pre-processing.
Bit Rate, GOP structure and GOP length
impact the delay. The IP GOP structure
will provide lower latency than Low
Delay.
Super Low Delay
Only available for HEVC and a single
channel:
The lowest delay is achieved by
removing GOP structure concepts and
concentrating on striping of P Frames or
complete I Frames. This selection will
provide the best latency delay
performance. No ANC stream
processing is available in this mode.
Aspect Ratio 16:9, 4:3
Does not affect the video encoding but
rather indicates what the desired aspect
ratio for the decoded picture (not the
pixel). If no other mechanism such as
WSS in the VBI is used, the video output
image will use this aspect ratio.
