  1. # Motion-compensated dfttest by twc
  2. # Aka: Really Really Really Slow
  3. #
  4. # v2 by BakaProxy
  5. # Aka: Even more Really Really Really slow
  6. # 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
  7. #
  8. #
  9. # v3.91 by A.SONY
  10. # make it work in normal avs again and some fix, and not that slow if you use it without lsb/lsb_in
  11. # add slice bool to use it to avoid artifacts with avstp
  12. # clean up
  13. # New Features
  14. #
  15. # Requirements:
  16. # dfttest
  17. # MVTools2
  18. #
  19. # Suggested:
  20. # Dither (for stack16 processing)
  21. #
  22. # Description of function parameters:
  23. #
  24. # pp = Clip to calculate vectors from (default input)
  25. # mc = Number of frames in each direction to compensate (default 2, max 5)
  26. # mdg = Run MDeGrain before dfttest (default false)
  27. # mdgSAD = thSAD for MDeGrain (default 400)
  28. # lsb = stack16 output and processing (default false)
  29. #
  30. # dfttest Y, U, V, sigma, sbsize, sosize, tbsize, and dither are supported.
  31. # Extra dfttest parameters may be passed via dfttest_params.
  32. # MVTools2 pel, thSCD, thSAD, blksize, overlap, dct, search, and
  33. # searchparam are also supported.
  34. #
  35. # sigma is the main control of dfttest strength.
  36. # tbsize should not be set higher than mc * 2 + 1.
