Combine images

[Thundik81]

I don't know the technical terms to describe what i want to do.

Make it easy!
I have x images with a single dot on it (different places)
I want that :
1st frame with 1 dot (001.png)
2nd frame with 2 dots (002.png over 001.png)
3rd frame with 3 dots (003.png over 002.png over 001.png)
and so on...

See this old thread - "Sticking" overlay - for a similar problem and its solution.

I miss something...

bg = ImageSource("img/%03d.png", 1, 50, 4).Crop(1,1,0,0).ConvertToRGB32()
out = BlankClip(bg)
ScriptClip(bg, """
out = Layer(out.Loop(2,0,0),bg.Trim(current_frame,-1),"add")
return out
""")

=

ImageSource("img/%03d.png", 1, 50, 4).Crop(1,1,0,0).ConvertToRGB32()

Assuming your images have transparency information, you need to load them in with ImageSource as RGB32 (not the default RGB24) in order to preserve that information.
bg = ImageSource("img/%03d.png", 1, 50, 4, pixel_type="RGB32").Crop(1,1,0,0)

With your current script, you are overlaying completely opaque frames each time, so only the topmost one is visible.

Of course! :thanks:
