how to apply a filter to a part of video ?

[MacDonkey]

Hello !

I would like to apply a filter to a part only of a video.

Ex : frfun3d(2,2) but only on a part

I thought to make a transparent square with a filter Overlay, where there I will use the filter Frfun3D, but I do not manage to apply the filter Frfun3D on the transparent square. :confused:

Ex :

clip1 = last
clip2 = Imagesource("H:\cache.bmp")
Overlay(clip1, clip2, x=1673, Y=67, opacity=0.005)


Anybody would have an idea ?

Sorry for my catastrophic English. :p


THX !

Hi !

I still can not find how to apply a filter on a part of video. :confused:

Please, could anybody give me an example to add a denoising on clip2 ?

Thank you and have a good day ! ;)

clip2.denoiser()

ApplyRange(clip clip, int start_frame, int end_frame, string filtername, args)

c1=crop(0,0,x1,0,align=true) #no needs if use overlay
c2=crop(x1,0,x2,y1,align=true) #no needs if use overlay
c4=crop(x1,y2,x2,0,align=true) #no needs if use overlay
c5=crop(x2,0,0,0,align=true) #no needs if use overlay
c3=c3.filter()
stackhorizontal(c1,stackvertical(c2,c3,c4),c5)#or Overlay(c3,x=x1,y=y1)
