 # Motion-compensated dfttest by twc
 # Aka: Really Really Really Slow
 #
 # v2 by BakaProxy
 # Aka: Even more Really Really Really slow
 # Added: Recalculate, (proper) 16 bit input handling, dither_luma_rebuild and some masking to prevent 16 bit data loss from 8 bit Mdegrain and Mcompensate
 #
 #
-# v3 by A.SONY
+# v3.1 by A.SONY
 # make it work in normal avs again and some fix, and not that slow if you use it without lsb/lsb_in
 # add slice bool to use it to avoid artifacts with avstp
 #
 # Requirements:
 # dfttest
 # MVTools2
 #
 # Suggested:
 # Dither (for stack16 processing)
 #
 # Description of function parameters:
 #
 # pp = Clip to calculate vectors from (default input)
 # mc = Number of frames in each direction to compensate (default 2, max 5)
 # mdg = Run MDeGrain before dfttest (default false)
 # mdgSAD = thSAD for MDeGrain (default undefined)
 # lsb = stack16 output and processing (default false)
 #
 # dfttest Y, U, V, sigma, sbsize, sosize, tbsize, and dither are supported.
 # Extra dfttest parameters may be passed via dfttest_params.
 # MVTools2 pel, thSCD, thSAD, blksize, overlap, dct, search, and
 # searchparam are also supported.
 #
 # sigma is the main control of dfttest strength.
 # tbsize should not be set higher than mc * 2 + 1.
