Sketching effect

Postby Autraya » Wed Nov 14, 2007 1:21 am

other than luma keying some red speed (angled, in greys with lotsa tweaking and then it looks shitty) I'm trying to find some thing that looks like there's shading/sketching goin on under my video.
Anyone know of a plug-in that's similar and I tried the sapphire auto paint it's not what I'm after?

Corran wrote a sketch() AVS function. I don't know if that's what you're looking for.

Code: Select all

#############################################################################
# Sketch by Corran (Eric Parsons)                                           #
#                                                                           #
#threshold = A lower number will produce more lines                         #
#            (or noise)(INT: 0-255; Default=4)                              #
#strength = Higher numbers will produce slightly thicker                    #
#           lines.  (INT: 0-255; Default=48)                                #
#luma_cap = If a low number is used then only strong lines in the           #
#           original source will be 'sketched'. (INT: 0-255; Default=191)   #
#                                                                           #
#Example:                                                                   #
#       Sketch(threshold=2, strength=75, luma_cap=255)                      #
#############################################################################

function sketch (clip a, int "threshold", int "strength", int "luma_cap"){
    strength = Default(strength, 48)
    luma_cap = Default(luma_cap, 191)
    thresh = Default(threshold, 4)

    b = Eval("a.FastLineDarken(strength="+String(strength)+",\
          threshold="+String(thresh)+",luma_cap="+String(luma_cap)+",\
          thinning=0)")
    c = Subtract(a,b).Levels(120, 1, 140, 0, 255)
    d = c.Levels(120, 1.5, 140, 0, 255).Invert()

    Return d
}


(does requre FastLineDarken() and MaskTools 1.5.1, not sure if they're in the newest AMVApp)

Video Gogh by ReVision is one to check out.

Tinderbox 2 also has the best plugin for outlining I've seen for AE called Contour.
