+		When both kVTCompressionPropertyKey_DataRateLimits and
+		kVTCompressionPropertyKey_AverageBitRate are supported,
+		it is recommended that kVTCompressionPropertyKey_AverageBitRate
+		be set when kVTCompressionPropertyKey_DataRateLimits is set.
+		If kVTCompressionPropertyKey_AverageBitRate is not specified,
+		an overall average bit rate target will be selected at a safe margin below
+		the kVTCompressionPropertyKey_DataRateLimits target, so that regional
+		overshoot in the encoding will not exceed the
+		kVTCompressionPropertyKey_DataRateLimits.
+		The overall average bitrate target generated from
+		kVTCompressionPropertyKey_DataRateLimits in the absence of
+		kVTCompressionPropertyKey_AverageBitRate may not be ideal for all
+		scenarios.
+		Encoding is more likely to undershoot a requested
+		kVTCompressionPropertyKey_AverageBitRate if the specified target is too
+		close to a hard limit specified by kVTCompressionPropertyKey_DataRateLimits.
