- Method Detail
  - getAdaptiveQuantization
```
@Stability(value=Stable)
 @Nullable
default String getAdaptiveQuantization()
```
    The adaptive quantization.
    This allows intra-frame quantizers to vary to improve visual quality.
  - getAfdSignaling
```
@Stability(value=Stable)
 @Nullable
default String 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.
  - getBitrate
```
@Stability(value=Stable)
 @Nullable
default Number 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.
  - getBufFillPct
```
@Stability(value=Stable)
 @Nullable
default Number getBufFillPct()
```
    The percentage of the buffer that should initially be filled (HRD buffer model).
  - getBufSize
```
@Stability(value=Stable)
 @Nullable
default Number getBufSize()
```
    The size of the buffer (HRD buffer model) in bits/second.
  - getColorMetadata
```
@Stability(value=Stable)
 @Nullable
default String getColorMetadata()
```
    Includes color space metadata in the output.
  - getColorSpaceSettings
```
@Stability(value=Stable)
 @Nullable
default Object getColorSpaceSettings()
```
    Settings to configure the color space handling for the video.
  - getEntropyEncoding
```
@Stability(value=Stable)
 @Nullable
default String getEntropyEncoding()
```
    The entropy encoding mode.
    Use cabac (must be in Main or High profile) or cavlc.
  - getFilterSettings
```
@Stability(value=Stable)
 @Nullable
default Object getFilterSettings()
```
    Optional filters that you can apply to an encode.
  - getFixedAfd
```
@Stability(value=Stable)
 @Nullable
default String 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.
  - getFlickerAq
```
@Stability(value=Stable)
 @Nullable
default String getFlickerAq()
```
    If set to enabled, adjusts the quantization within each frame to reduce flicker or pop on I-frames.
  - getForceFieldPictures
```
@Stability(value=Stable)
 @Nullable
default String 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.
  - getFramerateControl
```
@Stability(value=Stable)
 @Nullable
default String 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.
  - getFramerateDenominator
```
@Stability(value=Stable)
 @Nullable
default Number getFramerateDenominator()
```
    The frame rate denominator.
  - getFramerateNumerator
```
@Stability(value=Stable)
 @Nullable
default Number getFramerateNumerator()
```
    The frame rate numerator.
    The frame rate is a fraction, for example, 24000/1001 = 23.976 fps.
  - getGopBReference
```
@Stability(value=Stable)
 @Nullable
default String getGopBReference()
```
    If enabled, uses reference B frames for GOP structures that have B frames > 1.
  - getGopClosedCadence
```
@Stability(value=Stable)
 @Nullable
default Number 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.
  - getGopNumBFrames
```
@Stability(value=Stable)
 @Nullable
default Number getGopNumBFrames()
```
    The number of B-frames between reference frames.
  - getGopSize
```
@Stability(value=Stable)
 @Nullable
default Number getGopSize()
```
    The GOP size (keyframe interval) in units of either frames or seconds per gopSizeUnits.
    The value must be greater than zero.
  - getGopSizeUnits
```
@Stability(value=Stable)
 @Nullable
default String getGopSizeUnits()
```
    Indicates if the gopSize is specified in frames or seconds.
    If seconds, the system converts the gopSize into a frame count at runtime.
  - getLevel
```
@Stability(value=Stable)
 @Nullable
default String getLevel()
```
    The H.264 level.
  - getLookAheadRateControl
```
@Stability(value=Stable)
 @Nullable
default String getLookAheadRateControl()
```
    The amount of lookahead.
    A value of low can decrease latency and memory usage, while high can produce better quality for certain content.
  - getMaxBitrate
```
@Stability(value=Stable)
 @Nullable
default Number 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.
  - getMinIInterval
```
@Stability(value=Stable)
 @Nullable
default Number 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.
  - getNumRefFrames
```
@Stability(value=Stable)
 @Nullable
default Number getNumRefFrames()
```
    The number of reference frames to use.
    The encoder might use more than requested if you use B-frames or interlaced encoding.
  - getParControl
```
@Stability(value=Stable)
 @Nullable
default String 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.
  - getParDenominator
```
@Stability(value=Stable)
 @Nullable
default Number getParDenominator()
```
    The Pixel Aspect Ratio denominator.
  - getParNumerator
```
@Stability(value=Stable)
 @Nullable
default Number getParNumerator()
```
    The Pixel Aspect Ratio numerator.
  - getProfile
```
@Stability(value=Stable)
 @Nullable
default String getProfile()
```
    An H.264 profile.
  - getQualityLevel
```
@Stability(value=Stable)
 @Nullable
default String 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.
  - getQvbrQualityLevel
```
@Stability(value=Stable)
 @Nullable
default Number 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.
  - getRateControlMode
```
@Stability(value=Stable)
 @Nullable
default String 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.
  - getScanType
```
@Stability(value=Stable)
 @Nullable
default String getScanType()
```
    Sets the scan type of the output to progressive or top-field-first interlaced.
  - getSceneChangeDetect
```
@Stability(value=Stable)
 @Nullable
default String 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.
  - getSlices
```
@Stability(value=Stable)
 @Nullable
default Number 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.
  - getSoftness
```
@Stability(value=Stable)
 @Nullable
default Number getSoftness()
```
    Softness.
    Selects a quantizer matrix. Larger values reduce high-frequency content in the encoded image.
  - getSpatialAq
```
@Stability(value=Stable)
 @Nullable
default String getSpatialAq()
```
    If set to enabled, adjusts quantization within each frame based on the spatial variation of content complexity.
  - getSubgopLength
```
@Stability(value=Stable)
 @Nullable
default String 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.
  - getSyntax
```
@Stability(value=Stable)
 @Nullable
default String getSyntax()
```
    Produces a bitstream that is compliant with SMPTE RP-2027.
  - getTemporalAq
```
@Stability(value=Stable)
 @Nullable
default String getTemporalAq()
```
    If set to enabled, adjusts quantization within each frame based on the temporal variation of content complexity.
  - getTimecodeInsertion
```
@Stability(value=Stable)
 @Nullable
default String 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.
