Method Details
-
getAdaptiveQuantization
The adaptive quantization.This allows intra-frame quantizers to vary to improve visual quality.
- See Also:
-
getAfdSignaling
Indicates that AFD values will be written into the output stream.If afdSignaling is auto, the system tries to preserve the input AFD value (in cases where multiple AFD values are valid). If set to fixed, the AFD value is the value configured in the fixedAfd parameter.
- See Also:
-
getBitrate
The average bitrate in bits/second.This is required when the rate control mode is VBR or CBR. It isn't used for QVBR. In a Microsoft Smooth output group, each output must have a unique value when its bitrate is rounded down to the nearest multiple of 1000.
- See Also:
-
getBufFillPct
The percentage of the buffer that should initially be filled (HRD buffer model).- See Also:
-
getBufSize
The size of the buffer (HRD buffer model) in bits/second.- See Also:
-
getColorMetadata
Includes color space metadata in the output.- See Also:
-
getColorSpaceSettings
Settings to configure the color space handling for the video.- See Also:
-
getEntropyEncoding
The entropy encoding mode.Use cabac (must be in Main or High profile) or cavlc.
- See Also:
-
getFilterSettings
Optional filters that you can apply to an encode.- See Also:
-
getFixedAfd
A four-bit AFD value to write on all frames of video in the output stream.Valid only when afdSignaling is set to Fixed.
- See Also:
-
getFlickerAq
If set to enabled, adjusts the quantization within each frame to reduce flicker or pop on I-frames.- See Also:
-
getForceFieldPictures
This setting applies only when scan type is "interlaced." It controls whether coding is performed on a field basis or on a frame basis. (When the video is progressive, the coding is always performed on a frame basis.) enabled: Force MediaLive to code on a field basis, so that odd and even sets of fields are coded separately. disabled: Code the two sets of fields separately (on a field basis) or together (on a frame basis using PAFF), depending on what is most appropriate for the content.- See Also:
-
getFramerateControl
Indicates how the output video frame rate is specified.If you select "specified," the output video frame rate is determined by framerateNumerator and framerateDenominator. If you select "initializeFromSource," the output video frame rate is set equal to the input video frame rate of the first input.
- See Also:
-
getFramerateDenominator
The frame rate denominator.- See Also:
-
getFramerateNumerator
The frame rate numerator.The frame rate is a fraction, for example, 24000/1001 = 23.976 fps.
- See Also:
-
getGopBReference
If enabled, uses reference B frames for GOP structures that have B frames > 1.- See Also:
-
getGopClosedCadence
The frequency of closed GOPs.In streaming applications, we recommend that you set this to 1 so that a decoder joining mid-stream will receive an IDR frame as quickly as possible. Setting this value to 0 will break output segmenting.
- See Also:
-
getGopNumBFrames
The number of B-frames between reference frames.- See Also:
-
getGopSize
The GOP size (keyframe interval) in units of either frames or seconds per gopSizeUnits.The value must be greater than zero.
- See Also:
-
getGopSizeUnits
Indicates if the gopSize is specified in frames or seconds.If seconds, the system converts the gopSize into a frame count at runtime.
- See Also:
-
getLevel
The H.264 level.- See Also:
-
getLookAheadRateControl
The amount of lookahead.A value of low can decrease latency and memory usage, while high can produce better quality for certain content.
- See Also:
-
getMaxBitrate
For QVBR: See the tooltip for Quality level.For VBR: Set the maximum bitrate in order to accommodate expected spikes in the complexity of the video.
- See Also:
-
getMinIInterval
Meaningful only if sceneChangeDetect is set to enabled.This setting enforces separation between repeated (cadence) I-frames and I-frames inserted by Scene Change Detection. If a scene change I-frame is within I-interval frames of a cadence I-frame, the GOP is shrunk or stretched to the scene change I-frame. GOP stretch requires enabling lookahead as well as setting the I-interval. The normal cadence resumes for the next GOP. Note that the maximum GOP stretch = GOP size + Min-I-interval - 1.
- See Also:
-
getNumRefFrames
The number of reference frames to use.The encoder might use more than requested if you use B-frames or interlaced encoding.
- See Also:
-
getParControl
Indicates how the output pixel aspect ratio is specified.If "specified" is selected, the output video pixel aspect ratio is determined by parNumerator and parDenominator. If "initializeFromSource" is selected, the output pixels aspect ratio will be set equal to the input video pixel aspect ratio of the first input.
- See Also:
-
getParDenominator
The Pixel Aspect Ratio denominator.- See Also:
-
getParNumerator
The Pixel Aspect Ratio numerator.- See Also:
-
getProfile
An H.264 profile.- See Also:
-
getQualityLevel
Leave as STANDARD_QUALITY or choose a different value (which might result in additional costs to run the channel).- ENHANCED_QUALITY: Produces a slightly better video quality without an increase in the bitrate. Has an effect only when the Rate control mode is QVBR or CBR. If this channel is in a MediaLive multiplex, the value must be ENHANCED_QUALITY.
- STANDARD_QUALITY: Valid for any Rate control mode.
- See Also:
-
getQvbrQualityLevel
Controls the target quality for the video encode.This applies only when the rate control mode is QVBR. Set values for the QVBR quality level field and Max bitrate field that suit your most important viewing devices. Recommended values are: - Primary screen: Quality level: 8 to 10. Max bitrate: 4M - PC or tablet: Quality level: 7. Max bitrate: 1.5M to 3M - Smartphone: Quality level: 6. Max bitrate: 1M to 1.5M.
- See Also:
-
getRateControlMode
The rate control mode.QVBR: The quality will match the specified quality level except when it is constrained by the maximum bitrate. We recommend this if you or your viewers pay for bandwidth. VBR: The quality and bitrate vary, depending on the video complexity. We recommend this instead of QVBR if you want to maintain a specific average bitrate over the duration of the channel. CBR: The quality varies, depending on the video complexity. We recommend this only if you distribute your assets to devices that can't handle variable bitrates.
- See Also:
-
getScanType
Sets the scan type of the output to progressive or top-field-first interlaced.- See Also:
-
getSceneChangeDetect
The scene change detection.On: inserts I-frames when the scene change is detected. Off: does not force an I-frame when the scene change is detected.
- See Also:
-
getSlices
The number of slices per picture.The number must be less than or equal to the number of macroblock rows for progressive pictures, and less than or equal to half the number of macroblock rows for interlaced pictures. This field is optional. If you don't specify a value, MediaLive chooses the number of slices based on the encode resolution.
- See Also:
-
getSoftness
Softness.Selects a quantizer matrix. Larger values reduce high-frequency content in the encoded image.
- See Also:
-
getSpatialAq
If set to enabled, adjusts quantization within each frame based on the spatial variation of content complexity.- See Also:
-
getSubgopLength
If set to fixed, uses gopNumBFrames B-frames per sub-GOP.If set to dynamic, optimizes the number of B-frames used for each sub-GOP to improve visual quality.
- See Also:
-
getSyntax
Produces a bitstream that is compliant with SMPTE RP-2027.- See Also:
-
getTemporalAq
If set to enabled, adjusts quantization within each frame based on the temporal variation of content complexity.- See Also:
-
getTimecodeBurninSettings
- See Also:
-
getTimecodeInsertion
Determines how timecodes should be inserted into the video elementary stream.disabled: don't include timecodes. picTimingSei: pass through picture timing SEI messages from the source specified in Timecode Config.
