Overview
When passing Av1QvbrSettings as input to an Aws::Client method, you can use a vanilla Hash:
{
qvbr_quality_level: 1,
qvbr_quality_level_fine_tune: 1.0,
}
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.

Instance Attribute Details
#qvbr_quality_level ⇒ Integer
Required when you use QVBR rate control mode. That is, when you specify qvbrSettings within av1Settings. 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.
#qvbr_quality_level_fine_tune ⇒ Float
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.
