<description>With this filter one can use several methods to reduce or eliminate DCT blocks: adding noise (Gaussian distributed), sharpening, or blurring.</description>
<description>Determines the size of the blocks into which each frame is split before processing. The value represents both the width and height of the block, and cannot be less than 3.</description>
<description>Determines the amount of detail that must be present in a block for it to be processed. It represents the percentage of unique brightness levels within the block. For example, if block_size is set to 8, each block contains 64 pixels. If detail_min is 1 and detail_max is 50, a block will only be processed if it contains between 1 and 32 unique brightness levels.</description>

<description>Luma pixels in the range 0-luma_threshold will be offset by luma_offset within processed blocks. For example, if luma_threshold is 30 and luma_offset is -2, dark pixels (those with a luma between 0 and 30 inclusive) will have 2 subtracted from them, making them slightly darker still.</description>
