	Bit Depth	Color Space	Category	Description
Super	8-16 int / 32 float	unknown	unknown	Optional, it helps improve the precision of sub-pixel motion estimation and compensation, use it and get a quality boost or don't and get a performance boost
Basic	8-16 int / 32 float	unknown	unknown	The basic estimation does a wild block matching based motion compensation, it removes all obvious artifacts and serves as the reference to all later more specific artifacts removing functions
Deringing	8-16 int / 32 float	unknown	Deringing/Edge cleaning	Deringing removes ringing (aka. mosquito noise) artifacts caused by lossy compression.
Destaircase	8-16 int / 32 float	unknown	unknown	block based quantization sometimes zeros out high frequency coefficients and leaves the low frequency part (almost or completely) unprocessed, which yields staircase noise, a kind of artifacts that resembles blocking, and sometimes may considered as blocking, it shows as discontinuities (aliasing) along curving edges, and Destaircase kills it
Deblocking	8-16 int / 32 float	unknown	unknown	block based quantization sometimes zeros out high frequency coefficients and leaves the low frequency part (almost or completely) unprocessed, which yields staircase noise, a kind of artifacts that resembles blocking, and sometimes may considered as blocking, it shows as discontinuities (aliasing) along curving edges, and Destaircase kills it
