Overlay Clip isn't working properly(?)

[VideoMilk78]

I've been playing around with a script that overlays a cleaned clip wherever dirt is on the original and I've run into an issue where I can see the dirt through the cleaned clip? I have opacity set to 1 so this shouldn't be possible...

Post your script

Where is the mask ? Or how did you convert "wherever dirt is on the original" to the mask clip ?

The mask clip has to be 100% white for 100% affected areas, otherwise you will see dirt show through from the original . If that's the case, you'd have to fix the mask

I just did a make diff mask between original and cleaned.


Mask=debugmask(clip,cleaned,bc=BlankClip(Cleaned),color=color_white).mt_expand().mt_expand().mt_expand().mt_binarize().mt_inflate().mt_inflate().mt_inflate().tweak(sat=0)

The shimmering through may be a colorspace issue (YUV vs RGB) with the mask colorspace.
Here a demo. Step through the frames:
A=BlankClip(pixel_type="YUV422P8",color=color_red).subtitle("A")
B=BlankClip(pixel_type="YUV422P8",color=color_lime).subtitle("B")
mask1=BlankClip(pixel_type="YUV422P8",color=color_black) #or color_white
mask2=BlankClip(pixel_type="RGBP8",color=color_black) #or color_white

o1=overlay(A,B,x=50,y=50, mask=mask1) #shimmering
o2=overlay(A,B,x=50,y=50, mask=mask2) #no shimmering
interleave (o1,o2)

I restored both your threads. There is no reason to delete them i would assume.
