JPBD with subtitles from VARYG batch

Claude did this encode from tip to tail more or less after I fed it thewiki.moe, some private tracker encoding guides, and kageru.moe. Results look good to me, see what y'all think.

Settings:

--- Descale --

DESCALE = True
DESCALE_H = 900
DESCALE_KERNEL = "bicubic" # bicubic | bilinear | lanczos | spline16 | spline36
DESCALE_B = 1 / 3 # bicubic only (Mitchell-Netravali = 1/3, 1/3)
DESCALE_C = 1 / 3

--- Denoise --

DENOISE = False
DENOISE_STRENGTH = 1.0 # knlm 'h'. bm3dcuda is better if you have it.

--- Deband --

DEBAND = True
DEBAND_THRESHOLD = float(os.environ.get("DEBAND_THRESHOLD", "3.44")) # wiki multi-pass baseline
DEBAND_RADIUS = 16.0
DEBAND_GRAIN = float(os.environ.get("DEBAND_GRAIN", "0.5")) # low dither; multi-pass keeps flats stable
DEBAND_ITER = int(os.environ.get("DEBAND_ITER", "4")) # placebo passes; more clears stubborn banding
PROTECT_EDGES = True # mask line art so deband can't eat detail

--- Regrain --

REGRAIN = os.environ.get("REGRAIN", "1") == "1"
REGRAIN_STR = float(os.environ.get("REGRAIN_STR", "0.30")) # luma grain strength (~0.2-0.5 light)
REGRAIN_STR_C = float(os.environ.get("REGRAIN_STR_C", "0.0")) # chroma grain (usually 0 for anime)
REGRAIN_STATIC = os.environ.get("REGRAIN_STATIC", "0") == "1" # static grain = cheaper but less natural

--- Output --

OUT_DEPTH = 10 # 10-bit out (Main10) is standard for anime
