Properties

AdaptiveQuantization

Adaptive quantization. Allows intra-frame quantizers to vary to improve visual quality.

Required: No

Type: String

Update requires: No interruption

AfdSignaling

Indicates that AFD values will be written into the output stream. 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.

Required: No

Type: String

Update requires: No interruption

AlternativeTransferFunction

Whether or not EML should insert an Alternative Transfer Function SEI message to support backwards compatibility with non-HDR decoders and displays.

Required: No

Type: String

Update requires: No interruption

Bitrate

Average bitrate in bits/second. 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.

Required: No

Type: Integer

Update requires: No interruption

BufSize

Size of buffer (HRD buffer model) in bits.

Required: No

Type: Integer

Update requires: No interruption

ColorMetadata

Includes colorspace metadata in the output.

Required: No

Type: String

Update requires: No interruption

ColorSpaceSettings

Color Space settings

Required: No

Type: H265ColorSpaceSettings

Update requires: No interruption

FilterSettings

Optional filters that you can apply to an encode.

Required: No

Type: H265FilterSettings

Update requires: No interruption

FixedAfd

Four bit AFD value to write on all frames of video in the output stream. Only valid when afdSignaling is set to 'Fixed'.

Required: No

Type: String

Update requires: No interruption

FlickerAq

If set to enabled, adjust quantization within each frame to reduce flicker or 'pop' on I-frames.

Required: No

Type: String

Update requires: No interruption

FramerateDenominator

Framerate denominator.

Required: No

Type: Integer

Update requires: No interruption

FramerateNumerator

Framerate numerator - framerate is a fraction, e.g. 24000 / 1001 = 23.976 fps.

Required: No

Type: Integer

Update requires: No interruption

GopClosedCadence

Frequency of closed GOPs. 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.

Required: No

Type: Integer

Update requires: No interruption

GopSize

GOP size (keyframe interval) in units of either frames or seconds per gopSizeUnits. 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.

Required: No

Type: Double

Update requires: No interruption

GopSizeUnits

Indicates if the gopSize is specified in frames or seconds. If seconds the system will convert the gopSize into a frame count at run time.

Required: No

Type: String

Update requires: No interruption

Level

H.265 Level.

Required: No

Type: String

Update requires: No interruption

LookAheadRateControl

Amount of lookahead. A value of low can decrease latency and memory usage, while high can produce better quality for certain content.

Required: No

Type: String

Update requires: No interruption

MaxBitrate

For QVBR: See the tooltip for Quality level

Required: No

Type: Integer

Update requires: No interruption

MinIInterval

Only meaningful if sceneChangeDetect is set to enabled. 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

Required: No

Type: Integer

Update requires: No interruption

ParDenominator

Pixel Aspect Ratio denominator.

Required: No

Type: Integer

Update requires: No interruption

ParNumerator

Pixel Aspect Ratio numerator.

Required: No

Type: Integer

Update requires: No interruption

Profile

H.265 Profile.

Required: No

Type: String

Update requires: No interruption

QvbrQualityLevel

Controls the target quality for the video encode. 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

Required: No

Type: Integer

Update requires: No interruption

RateControlMode

Rate control mode. 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.

Required: No

Type: String

Update requires: No interruption

ScanType

Sets the scan type of the output to progressive or top-field-first interlaced.

Required: No

Type: String

Update requires: No interruption

SceneChangeDetect

Scene change detection.

Required: No

Type: String

Update requires: No interruption

Slices

Number of slices per picture. 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.

Required: No

Type: Integer

Update requires: No interruption

Tier

H.265 Tier.

Required: No

Type: String

Update requires: No interruption

TimecodeInsertion

Determines how timecodes should be inserted into the video elementary stream. - 'disabled': Do not include timecodes - 'picTimingSei': Pass through picture timing SEI messages from the source specified in Timecode Config

Required: No
