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


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.
