== Description ==
[[hqdn3dY]] is a modfication of the [[hqdn3d]] filter.

Changes include:
* Chroma processing disabled.
* Parameters {{Template:FuncDef3|ls}} and {{Template:FuncDef3|lt}} were renamed to {{Template:FuncDef3|sp}} and {{Template:FuncDef3|tp}}, respectively. 
* Parameters {{Template:FuncDef3|cs}}, {{Template:FuncDef3|ct}}, and {{Template:FuncDef3|restart}} were removed.
* <code>{{Template:FuncDef3|hqdn3d16Y}}</code> 16-bit processing using the interleaved 16bit hack aka Double Width (similar hack to [[Stack16]]).
<br>
<span style="color:red">'''Note:  Hqdn3dY is considered deprecated, use the updated [[hqdn3d]] plugin.'''</span>
<br>
<br>

== Requirements ==
* [x86] [[AviSynth+]] or [http://sourceforge.net/projects/avisynth2/ AviSynth 2.6 or greater]
* [x64] [[AviSynth+]]
* [[FAQ_different_types_content#How_do_I_recognize_progressive.2C_interlaced.2C_telecined.2C_hybrid_and_blended_content.3F|Progressive]] input only 
* Supported color formats: [[Y8]]

<br>
::{{Par2| |clip| }}
:::Input clip.
<br>
::{{Par2|sp|float|4.0}}
:::{{Template:FuncDef3|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.
<br>
::{{Par2|tp|float|6.0}}
:::{{Template:FuncDef3|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. 
<br>

== Examples ==
Hqdn3dY with all default values:
 [[AviSource]]("Blah.avi")
 Hdn3dY(sp=4.0, tp=6.0)


16 bit processing:
 [[ConvertBits|ConvertTo16bit()]] # if your source is not already 16-bit
 [[ConvertStacked|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.
