Av1Settings

public struct Av1Settings : AWSShape

Undocumented

  • Declaration

    Swift

    public static var _members: [AWSShapeMember]

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

    Declaration

    Swift

    public let adaptiveQuantization: Av1AdaptiveQuantization?

  • If you are using the console, use the Framerate setting to specify the frame rate for this output. If you want to keep the same frame rate as the input video, choose Follow source. If you want to do frame rate conversion, choose a frame rate from the dropdown list or choose Custom. The framerates shown in the dropdown list are decimal approximations of fractions. If you choose Custom, specify your frame rate as a fraction. If you are creating your transcoding job specification as a JSON file without the console, use FramerateControl to specify which value the service uses for the frame rate for this output. Choose INITIALIZE_FROM_SOURCE if you want the service to use the frame rate from the input. Choose SPECIFIED if you want the service to use the frame rate you specify in the settings FramerateNumerator and FramerateDenominator.

    Declaration

    Swift

    public let framerateControl: Av1FramerateControl?

  • Optional. Specify how the transcoder performs framerate conversion. The default behavior is to use duplicate drop conversion.

    Declaration

    Swift

    public let framerateConversionAlgorithm: Av1FramerateConversionAlgorithm?

  • When you use the API for transcode jobs that use frame rate conversion, specify the frame rate as a fraction. For example, 24000 / 1001 = 23.976 fps. Use FramerateDenominator to specify the denominator of this fraction. In this example, use 1001 for the value of FramerateDenominator. When you use the console for transcode jobs that use frame rate conversion, provide the value as a decimal number for Framerate. In this example, specify 23.976.

    Declaration

    Swift

    public let framerateDenominator: Int?

  • When you use the API for transcode jobs that use frame rate conversion, specify the frame rate as a fraction. For example, 24000 / 1001 = 23.976 fps. Use FramerateNumerator to specify the numerator of this fraction. In this example, use 24000 for the value of FramerateNumerator. When you use the console for transcode jobs that use frame rate conversion, provide the value as a decimal number for Framerate. In this example, specify 23.976.

    Declaration

    Swift

    public let framerateNumerator: Int?

  • Specify the GOP length (keyframe interval) in frames. With AV1, MediaConvert doesn’t support GOP length in seconds. This value must be greater than zero and preferably equal to 1 + ((numberBFrames + 1) * x), where x is an integer value.

    Declaration

    Swift

    public let gopSize: Double?

  • Maximum bitrate in bits/second. For example, enter five megabits per second as 5000000. Required when Rate control mode is QVBR.

    Declaration

    Swift

    public let maxBitrate: Int?

  • Specify the number of B-frames. With AV1, MediaConvert supports only 7 or 15.

    Declaration

    Swift

    public let numberBFramesBetweenReferenceFrames: Int?

  • Settings for quality-defined variable bitrate encoding with the AV1 codec. Required when you set Rate control mode to QVBR. Not valid when you set Rate control mode to a value other than QVBR, or when you don’t define Rate control mode.

    Declaration

    Swift

    public let qvbrSettings: Av1QvbrSettings?

  • ‘With AV1 outputs, for rate control mode, MediaConvert supports only quality-defined variable bitrate (QVBR). You can’‘t use CBR or VBR.’

    Declaration

    Swift

    public let rateControlMode: Av1RateControlMode?

  • Specify the number of slices per picture. This value must be 1, 2, 4, 8, 16, or 32. For progressive pictures, this value must be less than or equal to the number of macroblock rows. For interlaced pictures, this value must be less than or equal to half the number of macroblock rows.

    Declaration

    Swift

    public let slices: Int?

  • Adjust quantization within each frame based on spatial variation of content complexity.

    Declaration

    Swift

    public let spatialAdaptiveQuantization: Av1SpatialAdaptiveQuantization?

  • Undocumented

    Declaration

    Swift

    public init(adaptiveQuantization: Av1AdaptiveQuantization? = nil, framerateControl: Av1FramerateControl? = nil, framerateConversionAlgorithm: Av1FramerateConversionAlgorithm? = nil, framerateDenominator: Int? = nil, framerateNumerator: Int? = nil, gopSize: Double? = nil, maxBitrate: Int? = nil, numberBFramesBetweenReferenceFrames: Int? = nil, qvbrSettings: Av1QvbrSettings? = nil, rateControlMode: Av1RateControlMode? = nil, slices: Int? = nil, spatialAdaptiveQuantization: Av1SpatialAdaptiveQuantization? = nil)
