class Aws::MediaConvert::Types::Xavc4kProfileSettings

Required when you set (Profile) under (VideoDescription)>(CodecSettings)>(XavcSettings) to the value XAVC_4K.

@note When making an API call, you may pass Xavc4kProfileSettings

data as a hash:

    {
      bitrate_class: "BITRATE_CLASS_100", # accepts BITRATE_CLASS_100, BITRATE_CLASS_140, BITRATE_CLASS_200
      codec_profile: "HIGH", # accepts HIGH, HIGH_422
      flicker_adaptive_quantization: "DISABLED", # accepts DISABLED, ENABLED
      gop_b_reference: "DISABLED", # accepts DISABLED, ENABLED
      gop_closed_cadence: 1,
      hrd_buffer_size: 1,
      quality_tuning_level: "SINGLE_PASS", # accepts SINGLE_PASS, SINGLE_PASS_HQ, MULTI_PASS_HQ
      slices: 1,
    }

@!attribute [rw] bitrate_class

Specify the XAVC 4k (Long GOP) Bitrate Class to set the bitrate of
your output. Outputs of the same class have similar image quality
over the operating points that are valid for that class.
@return [String]

@!attribute [rw] codec_profile

Specify the codec profile for this output. Choose High, 8-bit, 4:2:0
(HIGH) or High, 10-bit, 4:2:2 (HIGH\_422). These profiles are
specified in ITU-T H.264.
@return [String]

@!attribute [rw] flicker_adaptive_quantization

The best way to set up adaptive quantization is to keep the default
value, Auto (AUTO), for the setting Adaptive quantization
(XavcAdaptiveQuantization). When you do so, MediaConvert
automatically applies the best types of quantization for your video
content. Include this setting in your JSON job specification only
when you choose to change the default value for Adaptive
quantization. Enable this setting to have the encoder reduce I-frame
pop. I-frame pop appears as a visual flicker that can arise when the
encoder saves bits by copying some macroblocks many times from frame
to frame, and then refreshes them at the I-frame. When you enable
this setting, the encoder updates these macroblocks slightly more
often to smooth out the flicker. This setting is disabled by
default. Related setting: In addition to enabling this setting, you
must also set Adaptive quantization (adaptiveQuantization) to a
value other than Off (OFF) or Auto (AUTO). Use Adaptive quantization
to adjust the degree of smoothing that Flicker adaptive quantization
provides.
@return [String]

@!attribute [rw] gop_b_reference

Specify whether the encoder uses B-frames as reference frames for
other pictures in the same GOP. Choose Allow (ENABLED) to allow the
encoder to use B-frames as reference frames. Choose Don't allow
(DISABLED) to prevent the encoder from using B-frames as reference
frames.
@return [String]

@!attribute [rw] gop_closed_cadence

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.
@return [Integer]

@!attribute [rw] hrd_buffer_size

Specify the size of the buffer that MediaConvert uses in the HRD
buffer model for this output. Specify this value in bits; for
example, enter five megabits as 5000000. When you don't set this
value, or you set it to zero, MediaConvert calculates the default by
doubling the bitrate of this output point.
@return [Integer]

@!attribute [rw] quality_tuning_level

Optional. Use Quality tuning level (qualityTuningLevel) to choose
how you want to trade off encoding speed for output video quality.
The default behavior is faster, lower quality, single-pass encoding.
@return [String]

@!attribute [rw] 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.
@return [Integer]
