<     <value>CABAC, or context adaptive binary arithmetic coding, is used by x264 to reduce the bitrate needed for a given quality by 15%. 
< This makes it very cool and very useful, and it should be left on whenever possible. However, it is incompatible with the iPod 5.5G, and makes the AppleTV struggle. 
< So turn it off for those. CABAC is a kind of entropy coding, which means that it compresses data by making shorthand symbols to represent long streams of data. 
< The "entropy" part means that the symbols it uses the most often are the smallest. 
< When you disable CABAC, another entropy coding scheme gets enabled, called CAVLC (context adaptive variable-length coding). 
< CAVLC is a lot less efficient, which is why it needs 15% more bitrate to achieve the same quality as CABAC.</value>

<     <value>x264 includes an in-loop deblocking filter. 
< What this means is that blocky compression artifacts are smoothed away when you play back the video. 
< It has two settings: strength and threshold, just like a simple filter in Photoshop. 
< Strength controls the amount of deblocking applied to the whole frame. 
< If you drop down below 0, you reduce the amount of blurring.
< Go too negative, and you'll get an effect somewhat like oversharpening an image. 
< Go into positive values, and the image may become too soft. 
< Threshold controls how sensitive the filter is to whether something in a block is detail that needs to be preserved: lower numbers blur details less. 
< The default deblocking values are 0 and 0. This does not mean zero deblocking. 
< It means x264 will apply the regular deblocking strength and thresholds the codec authors have selected as working the best in most cases. 
< While many, many people stick with the default deblocking values of 0,0, other people disagree. 
< Some prefer a slightly less blurred image for live action material, and use values like -2,-1 or -2,-2. Others will raise it to 1,1 or even 3,3 for animation. 
< While the values for each setting extend from -6 to 6, the consensus is that going below -3 or above 3 is worthless.

<     <value>Analysis controls how finely x264 divides up a frame to capture detail. 
< Full macroblocks are 16x16 pixels, but x264 can go down all the way to 4x4 blocks if it judges it necessary. 
< By default it only breaks up key frames that much. 
< To give x264 the freedom to make the best decisions for all frames, use "all" analysis. 
< If you want to create a high profile H.264 video (which is less compatible with the world at large than main profile),

< It can either look at other parts of the current frame (spatial) or compare against the preceding frame (temporal).
