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 (typically 350ms) achieved by
removing pre-processing functions. Bit Rate, GOP
structure and GOP length impact the delay. The IP GOP
structure will give lowest 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 give lowest
delay, but with reduced quality.
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.
GOP Length 4 to 250
Defines the nominal distance in steps of video frames
between two consecutive I frames in the encoded bit-
stream.
GOP Structure IP, IBP, IBBP, IBBBP, IBBBBBBBP
Sets the number of B frames between reference frames.
IBBBBBBBP can only be used for 720p video format
encoded with a H.264 video profile.
Closed GOPs Off, On
Enables or disables the usage of Group of Pictures in
which the predicted frames can have their reference from
outside the group.
Delay
Displays the actual video encoding delay. Read only
parameter.
