Avisynth: TemporalSmoother?
 
Hi,
Im using avisynth 2.0.8 and the optimal script,but I get this error:there is no function called TemporalSmoother,what is wrong with the script?:

#================================================= =====#
# -= AviSynth script by MovieStacker v2.0.0 (beta3) =- #
#================================================= =====#

LoadPlugin("D:\Programmer\MovieStacker\Filters\MPE G2Dec3.dll")
LoadPlugin("D:\Programmer\MovieStacker\Filters\STM edianFilter.dll")
LoadPlugin("D:\Programmer\MovieStacker\Filters\Gri pFit_preview.dll")
LoadPlugin("D:\Programmer\MovieStacker\Filters\UnF ilter.dll")

Mpeg2Source("D:\DVD2AVI.d2v")
GripCrop(704, 576, source_anamorphic=false)
GripSize(resizer="BicubicResize")
STMedianFilter(8, 32, 0, 0, 8, 32)
UnFilter(50,50)
TemporalSmoother(1,2)
MergeChroma(blur(1.50))
MergeLuma(blur(0.2))
GripBorders()

I must say im very pleased with the result without the "TemporalSmoother" but if it could get even better :D

buller,

TemporalSmoother is a function built in Mpeg2dec
and you're loading MPEG2Dec3 in the script!


:wink:

thx for reply.
I just thought MPEG2Dec3 is better?,what is the use of "TemporalSmoother"?

MPEG2Dec3 is better and for avisynth 2.5x and you're using 2.0.8 !

from Dividee temporalsmoother read-me :

This filter is an adaptive noise reducer, working along the time axis;
it is most effective when the image is not moving much.
Increase the filter strength to increase noise reduction,
and decrease it to reduce speckling and ghosting artifacts.
It is recommended that you combine this filter
with a spatial (area-based) noise reducer for greatest effect.

All frames no more than radius away are examined.
Minimum radius is 1, maximum is 7. Larger values are of course slower.
Default is 3, which is the value used in VirtualDub.
The default value for strength is 2.
Note that unlike its VirtualDub counterpart, this filter has no lag.
It ensures that the frames needed for its work are in its buffer.
Therefore, random access in the clip is slow, especially with a large radius.

Example:

# The filter effects in RGB and YUV are not 100% equivalent, especially with a high strength.
# Let's visualize the difference

cYUY2 = ConvertToRGB(TemporalSmoother(ConvertToYUY2,10))
cRGB = TemporalSmoother(10)
Subtract(cYUY2, cRGB)

....and i like too much of temporalsmoother but
i'm using avisynth 2.5x cos is faster!
:wink:

ok then,I didnt understand much of the TemporalSmoother describtion,but
it makes the picture look good :wink: .think maybe i will try avisynth 2.5x
The 1:35 hour long movie i encoded took 7-8 hours 8O
thx jorel for helping :D
