class Aws::MediaConvert::Types::H264QvbrSettings

Settings for quality-defined variable bitrate encoding with the H.265 codec. Use these settings only when you set QVBR for Rate control mode (RateControlMode).

@note When making an API call, you may pass H264QvbrSettings

data as a hash:

    {
      max_average_bitrate: 1,
      qvbr_quality_level: 1,
      qvbr_quality_level_fine_tune: 1.0,
    }

@!attribute [rw] max_average_bitrate

Use this setting only when Rate control mode is QVBR and Quality
tuning level is Multi-pass HQ. For Max average bitrate values suited
to the complexity of your input video, the service limits the
average bitrate of the video part of this output to the value that
you choose. That is, the total size of the video element is less
than or equal to the value you set multiplied by the number of
seconds of encoded output.
@return [Integer]

@!attribute [rw] qvbr_quality_level

Use this setting only when you set Rate control mode
(RateControlMode) to QVBR. Specify the target quality level for this
output. MediaConvert determines the right number of bits to use for
each part of the video to maintain the video quality that you
specify. When you keep the default value, AUTO, MediaConvert picks a
quality level for you, based on characteristics of your input video.
If you prefer to specify a quality level, specify a number from 1
through 10. Use higher numbers for greater quality. Level 10 results
in nearly lossless compression. The quality level for most
broadcast-quality transcodes is between 6 and 9. Optionally, to
specify a value between whole numbers, also provide a value for the
setting qvbrQualityLevelFineTune. For example, if you want your QVBR
quality level to be 7.33, set qvbrQualityLevel to 7 and set
qvbrQualityLevelFineTune to .33.
@return [Integer]

@!attribute [rw] qvbr_quality_level_fine_tune

Optional. Specify a value here to set the QVBR quality to a level
that is between whole numbers. For example, if you want your QVBR
quality level to be 7.33, set qvbrQualityLevel to 7 and set
qvbrQualityLevelFineTune to .33. MediaConvert rounds your QVBR
quality level to the nearest third of a whole number. For example,
if you set qvbrQualityLevel to 7 and you set
qvbrQualityLevelFineTune to .25, your actual QVBR quality level is
7.33.
@return [Float]
