timesmooth and dynamic noise reduction in avisynth

[86peaches]

i was just wondering if there are any avisynth versions of virtualdub's timesmooth (temporal smoother) or (more importantly) dynamic noise reduction plugins.

if there aren't any exact avisynth versions, any plugins that can do the same(/similar) job will do.

and finally, is it possible to use the above mentioned filters/plugins while frameserving. i heard not (for at least one of them anyway).

Forget about what you "heard". Have you tried either of them your self with a small AVI file while framserving?

AVISyth's equivs are...

TemporalSoften(radius, luma, chroma)

and

SpatialSoften(Radius, luma, chroma)

so dynamic noise reduction, which freezes out background noise (not sure if that's an accurate description), is temporal/spatial? which one?

and thanks for the help.

btw: the equivs you refer to are included in avisynth? right?

[snowmoon]

Temporal = locking/blending across frames
Spatial = locking/blending inside on frame

Yes they are both included in AVIsynth.

sorry if this is a bit stupid, but i've never used these before.

so what's the diff between the two, and what settings should i use to maximise lock, i'm not to bothered about blur, just whatever controls the lockage(don't think that's a word tho...).

If you like, you can use the VirtualDub filter itself.

Avisource()
function VD_DNR(clip clip, int threshold) 
{ 
  LoadVirtualdubPlugin(c:\program files\virtualdub\plugins\dnr.vdf", "_VD_DNR") 
  return clip._VD_DNR(threshold)
}

#ConvertToRGB()
VD_Dnr(25)#max is 31
#ConvertToYUY2()

It works similar to Avisynth's TemporalSoften or the exteral TemporalSmoother plugin. Make sure, the source is frame based, otherwise the filter might compare pixels of successive (i.e. different) fields, but I am not too sure about this.

General rule is, that you have to check the best filter setup by yourself, because every source is different (i.e. tests, tests, tests....). Usually you will get the best results if you combine a spatial with temporal softener.

also try http://www.avisynth.org this is probably better especially if you are using avisynth 2.6
