-- | Only use this setting when you change the default value, AUTO, for the
-- setting H264AdaptiveQuantization. When you keep all defaults, excluding
-- H264AdaptiveQuantization and all other adaptive quantization from your
-- JSON job specification, MediaConvert automatically applies the best
-- types of quantization for your video content. When you set
-- H264AdaptiveQuantization to a value other than AUTO, the default value
-- for H264FlickerAdaptiveQuantization is Disabled (DISABLED). Change this
-- value to Enabled (ENABLED) to 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. To manually
-- enable or disable H264FlickerAdaptiveQuantization, you must set Adaptive
-- quantization (H264AdaptiveQuantization) to a value other than AUTO.
