/**
 * 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. Change this value to 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 to a
 * value other than AUTO.
