Overview

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,
}

Settings for quality-defined variable bitrate encoding with the H.264 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.

Instance Attribute Details

#max_average_bitrateInteger

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.

Returns:

  • (Integer)

end

#qvbr_quality_levelInteger

Required when you use QVBR rate control mode. That is, when you specify qvbrSettings within h264Settings. Specify the general target quality level for this output, from 1 to 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.

end

#qvbr_quality_level_fine_tuneFloat

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.
