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.\n\nThreshold controls how sensitive the filter is to whether something in a block is detail that needs to be preserved: lower numbers blur details less.\n\nThe 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.\n\nWhile many, many people stick with the default deblocking values of 0,0, and you should never change the deblocking without disabling adaptive quantization, 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.
