Properties
AfdSignaling-
Configures whether MediaLive will write AFD values into the video. AUTO: MediaLive will try to preserve the input AFD value (in cases where multiple AFD values are valid). FIXED: the AFD value will be the value configured in the fixedAfd parameter. NONE: MediaLive won't write AFD into the video.
Required: No
Type: String
Update requires: No interruption
BitDepth-
Specifies the bit depth for the output encode. Choose a value. Or leave the field empty to use the default, which is 8 bit.
Required: No
Type: String
Update requires: No interruption
Bitrate-
Average bitrate in bits/second. Required when the rate control mode is CBR. Not used for QVBR.
Required: No
Type: Integer
Update requires: No interruption
BufSize-
The size of the buffer (HRD buffer model) in bits.
Required: No
Type: Integer
Update requires: No interruption
ColorSpaceSettings-
Specify the type of color space to apply or choose to pass through. The default is to pass through the color space that is in the source.
Required: No
Type: Av1ColorSpaceSettings
Update requires: No interruption
FixedAfd-
Complete this property only if you set the afdSignaling property to FIXED. Choose the AFD value (4 bits) to write on all frames of the video encode.
Required: No
Type: String
Update requires: No interruption
FramerateDenominator-
The denominator for the framerate. Framerate is a fraction, for example, 24000 / 1001.
Required: No
Type: Integer
Update requires: No interruption
FramerateNumerator-
The numerator for the framerate. Framerate is a fraction, for example, 24000 / 1001.
Required: No
Type: Integer
Update requires: No interruption
GopSize-
The GOP size (keyframe interval). If GopSizeUnits is frames, GopSize must be a whole number and must be greater than or equal to 1. If GopSizeUnits is seconds, GopSize must be greater than 0, but it can be a decimal.
Required: No
Type: Number
Update requires: No interruption
GopSizeUnits-
Choose the units for the GOP size: FRAMES or SECONDS. For SECONDS, MediaLive converts the size into a frame count at run time.
Required: No
Type: String
Update requires: No interruption
Level-
Sets the level. This parameter is one of the properties of the encoding scheme for AV1.
Required: No
Type: String
Update requires: No interruption
LookAheadRateControl-
Sets the amount of lookahead. A value of LOW can decrease latency and memory usage. A value of HIGH can produce better quality for certain content.
Required: No
Type: String
Update requires: No interruption
MaxBitrate-
The maximum bitrate to assign. For recommendations, see the description for qvbrQualityLevel.
Required: No
Type: Integer
Update requires: No interruption
MinBitrate-
Used for QVBR rate control mode only. Optional. Enter a minimum bitrate if you want to keep the output bitrate about a threshold, in order to prevent the downstream system from de-allocating network bandwidth for this output.
Required: No
Type: Integer
Update requires: No interruption
MinIInterval-
Applies only if you enable SceneChangeDetect. Sets the interval between frames. This property ensures a minimum separation between repeated (cadence) I-frames and any I-frames inserted by scene change detection (SCD frames). Enter a number for the interval, measured in number of frames.
Required: No
Type: Integer
Update requires: No interruption
ParDenominator-
The denominator for the output pixel aspect ratio (PAR).
Required: No
Type: Integer
Update requires: No interruption
ParNumerator-
The numerator for the output pixel aspect ratio (PAR).
Required: No
Type: Integer
Update requires: No interruption
QvbrQualityLevel-
Controls the target quality for the video encode. With QVBR rate control mode, the final quality is the target quality, constrained by the maxBitrate. Set values for the qvbrQualityLevel property and maxBitrate property that suit your most important viewing devices.
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.
Required: No
Type: String
Update requires: No interruption
SceneChangeDetect-
Controls whether MediaLive inserts I-frames when it detects a scene change. ENABLED or DISABLED.
Required: No
Type: String
Update requires: No interruption
SpatialAq-
Spatial AQ makes adjustments within each frame based on spatial variation of content complexity. Enabled: MediaLive will determine the appropriate level of spatial AQ to apply. Disabled: No spatial AQ.
Required: No
Type: String
Update requires: No interruption
TemporalAq-
Temporal AQ makes adjustments within each frame based on variations in content complexity over time. Enabled: MediaLive will determine the appropriate level of temporal AQ to apply. Disabled: No temporal AQ.
Required: No
Type: String
Update requires: No interruption
TimecodeBurninSettings-
Configures the timecode burn-in feature. If you enable this feature, the timecode will become part of the video.
Required: No
Type: TimecodeBurninSettings
Update requires: No interruption
TimecodeInsertion-
Controls how MediaLive inserts timecodes into the video output encode. DISABLED: Do not insert timecodes. METADATA_OBU: Include timecodes. MediaLive inserts timecode metadata based on the timecode from the source specified in the Timecode Config property.
Required: No
Type: String
Update requires: No interruption
