Description
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.
Constant Bit Rate operation.
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.
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.
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.
Defines the nominal distance in steps of video frames
between two consecutive I frames in the encoded bit-
stream.
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.
Enables or disables the usage of Group of Pictures in
which the predicted frames can have their reference from
outside the group.
When enabled, minimizes the negative effect the scene
changes have on the bit rate by inserting an I-Frame when
a change is detected. It also affects the GOP length.
Displays the actual video encoding delay. Read only
parameter.
Detects if the video is a still picture, and adjusts the
encoded video bit rate accordingly when operating in VBR
mode.
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.
Sets the characteristics of the filter placed in the feedback
loop of the encoder. Applying the filter to the picture can
increase picture sharpness.
Controls the bit rate at which the encoder switches from
CABAC to CAVLC entropy coding.
Defines how the SEi messages are formatted in the picture
header for H264. For combined, all the different types of
messages (for example AFD) are bundles into one NAL
packet. For Mediaroom each type of message is put into
its own NAL packet. This was done for STB compatibility
issues
Configures output to include information in the SEI
message depending on the 3D mode. Frame Sync Delay
in SEI is only available for CE-x with CE/SWO/CE-x/H264,
CE/SWO/CE-x/HD and CE/SWO/CE-x/3D licenses.
