exclude filters an area of video

[byme]

Is possible have a script when a video area remains excluded?

for example

I would be more concerned about the colors. Why the woman has green hair, and why the shadows of skin are green and purple.

Yes. You can do it with creative use of multiple processing of the same clip combined with masked Overlay(). There may be a simpler way but I am not aware of it.

depend probably of the capture card... :confused:

you explain me, or make me a sample script for how to?

:thanks:

Slightly simpler is to Crop out the area not to be processed and Overlay the result back onto the filtered original.

c = Crop(x,y,w,h)
Filter(...).Overlay(c, x=x, y=y)

This avoids the need for a mask, but can only be used if the cropped area respects possible mod2 restrictions.

great Gavino, it worked!

thanks also to Didée and neuron2


can put the crop first of BlindDeHalo in this script created by Didée

src = AviSource("C:\Users\Propietario\Documents\Edit Video\Untitled 1.avi").ConvertToYV12()
c = Crop(942, 572, 80, 80)
BDH3 = src.BlindDeHalo3(strength=80, sharpness=0.0, interlaced=false)
#BDH3_med = BDH3.repair(BDH3.MedianBlur(2,-333,-333),1) # using radius 2
BDH3_med = BDH3.repair(BDH3.repair(BDH3.MedianBlur(3,-333,-333),1),1) # using radius 3
BDH3_diff = mt_makediff(src,BDH3)
BDH3_med_diff = mt_makediff(BDH3,BDH3_med)
DD = mt_lutxy(BDH3_diff,BDH3_med_diff,"x 128 - y 128 - * 0 < 128 x 128 - abs y 128 - abs < x y ? ?")

BDH3.mt_adddiff(DD,U=2,V=2) # the result

FastLineDarkenMOD2(strength=48, luma_cap=255, threshold=0, thinning=96)
Overlay(c, x=942, y=572)
GradFunkMirror()
ConvertToRGB()

in this way gives me error

say that I should adjust colors?Well, sorry. Seems that my browser is to blame!

FireFox is showing me bad colors on this picture. Internet Explorer 8 is showing it as intended. This is what I've seen:

FireFox 3.6.4:

Did you use Software with Color Managment to create this screenshot?


OT: By accident, someone knows if it's a setting in FireFox that needs to be adjusted?

(For years I've been using the dont-you-ever-useit IE. Now I've switched to the behailed FireFox. And now this. Hehe.)

Edit: Nope. gfx.color_managment.XXX in FF is already set. Playing with the settings eventually makes all other content rendered falsely. But it never cuts into that PNG graphic, which always looks green & purple.

Another possibility: selective cropping && filtering,
++ the required combination of Stacks().

Yes, I'm an idiot who likes to complicate things. :o :D

src = AviSource("C:\Users\Propietario\Documents\Edit Video\Untitled 1.avi").ConvertToYV12()
c = Crop(942, 572, 80, 80)

You haven't given Crop any input to work on. Here you need
c = src.Crop(942, 572, 80, 80)

Yes, instead of using Overlay, you can construct the complete frame from a combination of 'StackHorizontal's and 'StackVertical's. A bit more complicated, but this will be faster.

[Guest]

A bit more complicated... A bit more? :eek:

For a 80x80 exclusion area, it's just not worth the hassle. It could even be that the overhead from calling the filter(s) multiple times (for the surrounding slices) makes the overall process slower.

That sort of exclusion is rather sloppy anyway. Depending on the actual kind of filtering, you'll have not much fun with the borders of the exclusion area. Eventually the whole rectangle will "stick out", think about color adjustments and such.

By 'it', are you referring to the StackHorizontal/Vertical approach?
You only need to call the filter once on the whole clip, then chop it up with Crop and put the various pieces together, along with the unfiltered section, using the StackXXX. Overlay is quite slow and memory-intensive, while Crop and Stack are very fast.
And if you write it as a function, you only have the hassle once and you can reuse the code on other occasions.

You're right, in general terms. But here I think the exclusion area is a logo, which sticks out anyway.

Ah, okay ... yes, I was thinking [that you were thinking] of individually processing the surrounding slices. I didn't see that you had Overlay is quite slow and memory-intensive in mind.

Sure, Overlay. One of my least-beloved Avisynth filters.

When colorspace allows, Layer() is faster. And MaskTools' "mt_lutxy()" is even faster. Both have those often-forgotten "x" and "y" parameters that allow to offset the secondary clip.

better that way...

I did not understand what is Stacks() :p

StackHorizontal() and StackVertical()
