Description

hqdn3dY is a modfication of the hqdn3d filter.

Changes include:

• Chroma processing disabled.
• Parameters ls and lt were renamed to sp and tp, respectively.
• Parameters cs, ct, and restart were removed.
• hqdn3d16Y 16-bit processing using the interleaved 16bit hack aka Double Width (similar hack to Stack16).

Requirements

• [x86] AviSynth+ or AviSynth 2.6 or greater
• [x64] AviSynth+
• Progressive input only
• Supported color formats: Y8

Syntax and Parameters

hqdn3dY (clip, float "sp", float "tp")

hqdn3d16Y (clip, float "sp", float "tp")

clip   =

Input clip.

float  sp = 4.0

sp (0-255) is the strength of the spatial filtering on the luma channel. Increasing this value will improve the smoothing but may overblur; anything above about 10 is probably not a good idea.

float  tp = 6.0

tp (0-255) is the strength of the temporal filtering on the luma channel. Increasing this value will improve the smoothing but may cause ghosting; anything above about 13 is probably not a good idea.

Examples

Hqdn3dY with all default values:

AviSource("Blah.avi")
Hdn3dY(sp=4.0, tp=6.0)

16 bit processing:

ConvertTo16bit() # if your source is not already 16-bit
ConvertToDoubleWidth()
hqdn3d16Y (sp=4.0, tp=6.0)
ConvertFromDoubleWidth(bits=16)

To denoise luma and chroma (YUV):

y = ConvertToY8()
u = UToY8()
v = VToY8()
y = y.Hqdn3dY(sp=10.0, tp=0.0)
u = u.Hqdn3dY(sp=10.0, tp=0.0)
v = v.Hqdn3dY(sp=10.0, tp=0.0)
YToUV(u,v,y)

Or to denoise RGB:

r = ShowRed("Y8")
g = ShowGreen("Y8")
b = ShowBlue("Y8")
r = r.Hqdn3dY(sp=10.0, tp=0.0)
g = g.Hqdn3dY(sp=10.0, tp=0.0)
b = b.Hqdn3dY(sp=10.0, tp=0.0)
MergeRGB(r,g,b)

You can view the result of an individual channel and tweak it by entering a channel clip variable (y,u,v,r,g,b) after this code.
