Setting	Explanation
BlurComplexity	Apply a Gaussian blur with the given radius to the quantizer
	curve. This value means the quantizer assigned to each frame
	is blurred temporally with its neighbors to limit quantizer
	fluctuations.
BQuantFactor	This value sets the targets average reduction in bit rate for B-
	frames as compared to P-frames. Higher values increase the
	quality of B-frames. This value makes them better references,
	which can improve the overall image quality. The problem is
	that the extra bits taken by the B-frames are taken from the P-
	frames, which makes this variable a balancing act.
BQuantOffset	This value is the quantizer scale offset between I-P-B-frames.
ChromaOffset	The encoder normally encodes all 3 color planes (luma, U
	(chroma), V (chroma) ) at the same quantizer. The system adds
	this value to the quantizers for the U and V planes. This value
	allows you to bias the encode in favor of brightness (luma) by
	setting positive values (chroma fields will have higher
	quantizers), or in favor of color (chroma) by setting negative
	values (chroma fields will have lower quantizers).
	The encoder only encodes the luma and chroma planes at the
	quantizer up to quantizer 29. After this, chroma is
	progressively quantized by a lower amount than luma until
	you end with luma at quantizer 51. This behavior is not
	adjustable, as it is required by the H.264 standard.
ConstantQuantizationRateControl	This value sets the encoder to use Constant Quantization Rate
	Control. It keeps the encoding at a constant quantizer and
	doesn’t restrict to target a certain bit rate, but rather restricts
	to a certain quality no matter what bit rate it needs to use on
	each frame to keep quality constant. This value is mostly for
	quality encodes, set to -1to disable this encode mode.
Level	This value sets the level flag in the output bit stream (as
	defined by Annex A of the H.264 Standard) permissible levels
	include:
	1, 1.1, 1.2, 1.3, 2, 2.1, 2.2, 3, 3.1, 3.2, 4, 4.1, 4.2, 5, and 5.1
	The encoder does not support level 1b from the specification.
MaxBFramesBetweenNonBFrames	This value sets the maximum number of concurrent B-frames
	that can be used. B-frames are similar to P-frames, except they
	can use motion prediction from future frames as well. This
	value can lead to significantly better efficiency in terms of
	compression ratio.
NoiseReduction	This value performs adaptive pseudo-dead zone noise
	reduction, estimates film noise based on the value set and
	attempts to remove the noise by dropping small details before
