Properties
AdaptiveQuantization
Adaptive quantization.
virtual string AdaptiveQuantization { get; }
Property Value
System.String
Remarks
Allows intra-frame quantizers to vary to improve visual quality.
AfdSignaling
Indicates that AFD values will be written into the output stream.
virtual string AfdSignaling { get; }
Property Value
System.String
Remarks
If afdSignaling is "auto", the system will try to preserve the input AFD value (in cases where multiple AFD values are valid). If set to "fixed", the AFD value will be the value configured in the fixedAfd parameter.
AlternativeTransferFunction
Whether or not EML should insert an Alternative Transfer Function SEI message to support backwards compatibility with non-HDR decoders and displays.
virtual string AlternativeTransferFunction { get; }
Property Value
System.String
Remarks
Bitrate
Average bitrate in bits/second.
virtual Nullable<double> Bitrate { get; }
Property Value
System.Nullable<System.Double>
Remarks
Required when the rate control mode is VBR or CBR. Not used for QVBR. In an MS Smooth output group, each output must have a unique value when its bitrate is rounded down to the nearest multiple of 1000.
BufSize
Size of buffer (HRD buffer model) in bits.
virtual Nullable<double> BufSize { get; }
Property Value
System.Nullable<System.Double>
Remarks
ColorMetadata
Includes colorspace metadata in the output.
virtual string ColorMetadata { get; }
Property Value
System.String
Remarks
ColorSpaceSettings
Color Space settings.
virtual object ColorSpaceSettings { get; }
Property Value
System.Object
Remarks
FilterSettings
Optional filters that you can apply to an encode.
virtual object FilterSettings { get; }
Property Value
System.Object
Remarks
FixedAfd
Four bit AFD value to write on all frames of video in the output stream.
virtual string FixedAfd { get; }
Property Value
System.String
Remarks
Only valid when afdSignaling is set to 'Fixed'.
FlickerAq
If set to enabled, adjust quantization within each frame to reduce flicker or 'pop' on I-frames.
virtual string FlickerAq { get; }
Property Value
System.String
Remarks
FramerateDenominator
Framerate denominator.
virtual Nullable<double> FramerateDenominator { get; }
Property Value
System.Nullable<System.Double>
Remarks
FramerateNumerator
Framerate numerator - framerate is a fraction, e.g. 24000 / 1001 = 23.976 fps.
virtual Nullable<double> FramerateNumerator { get; }
Property Value
System.Nullable<System.Double>
Remarks
GopClosedCadence
Frequency of closed GOPs.
virtual Nullable<double> GopClosedCadence { get; }
Property Value
System.Nullable<System.Double>
Remarks
In streaming applications, it is recommended that this be set to 1 so a decoder joining mid-stream will receive an IDR frame as quickly as possible. Setting this value to 0 will break output segmenting.
GopSize
GOP size (keyframe interval) in units of either frames or seconds per gopSizeUnits.
virtual Nullable<double> GopSize { get; }
Property Value
System.Nullable<System.Double>
Remarks
If gopSizeUnits is frames, gopSize must be an integer and must be greater than or equal to 1. If gopSizeUnits is seconds, gopSize must be greater than 0, but need not be an integer.
GopSizeUnits
Indicates if the gopSize is specified in frames or seconds.
virtual string GopSizeUnits { get; }
Property Value
System.String
Remarks
If seconds the system will convert the gopSize into a frame count at run time.
Level
H.265 Level.
virtual string Level { get; }
Property Value
System.String
Remarks
LookAheadRateControl
Amount of lookahead.
virtual string LookAheadRateControl { get; }
Property Value
System.String
Remarks
A value of low can decrease latency and memory usage, while high can produce better quality for certain content.
MaxBitrate
For QVBR: See the tooltip for Quality level.
virtual Nullable<double> MaxBitrate { get; }
Property Value
System.Nullable<System.Double>
Remarks
MinIInterval
Only meaningful if sceneChangeDetect is set to enabled.
virtual Nullable<double> MinIInterval { get; }
Property Value
System.Nullable<System.Double>
Remarks
Defaults to 5 if multiplex rate control is used. 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 and/or stretched to the scene change I-frame. GOP stretch requires enabling lookahead as well as setting I-interval. The normal cadence resumes for the next GOP. Note: Maximum GOP stretch = GOP size + Min-I-interval - 1
ParDenominator
Pixel Aspect Ratio denominator.
virtual Nullable<double> ParDenominator { get; }
Property Value
System.Nullable<System.Double>
Remarks
ParNumerator
Pixel Aspect Ratio numerator.
virtual Nullable<double> ParNumerator { get; }
Property Value
System.Nullable<System.Double>
Remarks
Profile
H.265 Profile.
virtual string Profile { get; }
Property Value
System.String
Remarks
QvbrQualityLevel
Controls the target quality for the video encode.
virtual Nullable<double> QvbrQualityLevel { get; }
Property Value
System.Nullable<System.Double>
Remarks
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:
RateControlMode
Rate control mode.
virtual string RateControlMode { get; }
Property Value
System.String
Remarks
QVBR: Quality will match the specified quality level except when it is constrained by the maximum bitrate. Recommended if you or your viewers pay for bandwidth. CBR: Quality varies, depending on the video complexity. Recommended only if you distribute your assets to devices that cannot handle variable bitrates. Multiplex: This rate control mode is only supported (and is required) when the video is being delivered to a MediaLive Multiplex in which case the rate control configuration is controlled by the properties within the Multiplex Program.
ScanType
Sets the scan type of the output to progressive or top-field-first interlaced.
virtual string ScanType { get; }
Property Value
System.String
Remarks
SceneChangeDetect
Scene change detection.
virtual string SceneChangeDetect { get; }
Property Value
System.String
Remarks
Slices
Number of slices per picture.
virtual Nullable<double> Slices { get; }
Property Value
System.Nullable<System.Double>
Remarks
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; when no value is specified the encoder will choose the number of slices based on encode resolution.
Tier
H.265 Tier.
virtual string Tier { get; }
Property Value
System.String
Remarks
TimecodeBurninSettings
virtual object TimecodeBurninSettings { get; }
Property Value
System.Object
Remarks
TimecodeInsertion
