Parameter Values Description
Stills Detection Off, On
Detects if the video is a still picture, and adjusts the
encoded video bit rate accordingly when operating in VBR
mode.
Film Mode*
Off, On
Sets encoding parameters that give better image quality
for film like sources. Available only for frame rates of 29.97
or 59.94 Hz when the resolution is set to other than SIF.
Inloop Filter
#
High, Normal, Low, Very Low, Auto
Sets the characteristics of the filter placed in the feedback
loop of the encoder. Applying the filter to the picture can
increase picture sharpness.
SEI Encapsulation
Mode
#
Combined, Mediaroom
Sets the SEI messages in combined mode where all the
SEI messages are combines into one NAL unit or into
Mediaroom mode compliance where each SEI message
has its own NAL start.
* Only applicable when the video profile is set to MPEG-2.
#
Only applicable when the video profile is set to H.264.
Only applicable when the video profile is set to MPEG-2 and the frame rate is 29.97 Hz or 59.94 Hz.
Second Video Encoding
The following parameters are available on the Encode tab of the Properties widget
on the Service Configuration page when a video component is selected in the
Outputs widget. The same parameters can be accessed through the
Advanced/EI9001/Video/Video 1/Video/Second Video/Video Encoder menu on
the front panel.
Table 5.9 Secondary Video Encoding Parameters
Parameter Values Description
Profile
Profile Off,
SD MPEG-2 Main Profile Main Level 4:2:0 8 bit,
SD H.264 Main Profile Level 3.0 4:2:0 8 bit,
SD H.264 High Profile Level 3.0 4:2:0 8 bit,
Sets the encoder profile. The profile will affect the allowed
bit-rate range. The secondary video encode will be of the
same coding standard as the primary video encode.
Resolution 720 x 576, 720 x 480
Read Only. Indicates the horizontal and vertical resolution
of the secondary encoded video. This is fixed, and
dependent on the main encoded video component for
frame rate.
Buffer Mode CBR
Read Only. The second video is run at Constant Bit Rate
in order to align the timing with the Main Video.
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.
Aspect Ratio 4:3, 16:9, Follow Input
Signaling of the picture aspect ratio. This setting does not
affect the video processing. The downstream decoder will
use this setting in the absence of other information (e.g.
WSS in VBI).
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, Auto Sets the number of B frames between reference frames.
