-- | 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 H264TemporalAdaptiveQuantization is Enabled (ENABLED). Keep this
-- default value to adjust quantization within each frame based on temporal
-- variation of content complexity. When you enable this feature, the
-- encoder uses fewer bits on areas of the frame that aren\'t moving and
-- uses more bits on complex objects with sharp edges that move a lot. For
-- example, this feature improves the readability of text tickers on
-- newscasts and scoreboards on sports matches. Enabling this feature will
-- almost always improve your video quality. Note, though, that this
-- feature doesn\'t take into account where the viewer\'s attention is
-- likely to be. If viewers are likely to be focusing their attention on a
-- part of the screen that doesn\'t have moving objects with sharp edges,
-- such as sports athletes\' faces, you might choose to set
-- H264TemporalAdaptiveQuantization to Disabled (DISABLED). Related
-- setting: When you enable temporal quantization, adjust the strength of
-- the filter with the setting Adaptive quantization
-- (adaptiveQuantization). To manually enable or disable
-- H264TemporalAdaptiveQuantization, you must set Adaptive quantization
-- (H264AdaptiveQuantization) to a value other than AUTO.
