While looking at one of the older KVCD guides I found this script

Code:
## Dynamic Linear Adaptive Filtering and Scene Change Detection ##
#
# ( Portions from AviSynth's manual ) - This will apply temporalsoften to
# very static scenes, and apply variable blur on moving scenes.
# We also assign a variable - and this is why a line break is inserted:

ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf > 2.5 ? asharp( -(fmin((nf/30), 1)), 0 ) : \
TemporalSoften(2,7,7,3,2) ")

#
# Scene change detection ( kwag ) - If a scene change is detected, we
# blur heavily. This affects the scene before and the one after the
# scene change, thus providing a softer transition for the encoder instead
# of a sharp "spike".
# If it's not a scene change, then we just blur dynamically, depending on
# the action.

ScriptClip("nf > scd_trigger ? asharp( -2,0) : asharp(0,0) ")
Is it still valid and are there any improvised or new versions available!!!

it looks like an older version of the MA script. It also blurs the scene when high motion is detected, and kwag's name is in it.....

Obsolete. First attempt of MA filtering actually.

I saw you had done some improvements in the scripts(under optimal scripts), but where is the most recent script, complete in one form.
