-- | 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.
