Copying old frames into the actual one… “onion” effect from Flash
Hey guys,
lets try to explain this with an example: I create three PNGs, each showing a different letter (a.png, b.png, c.png). So these show “a”, then “b” and then “c” when imported as an image sequence.
What I need is an effect that “blends” every old frame into the new frames. So at first I see an “a”, then the blended combination of “a+b” and then “a+b+c” instead of “a”, “b”, “c”. Fancy settings like overlay, multiply and screen would be cool, but aren’t necessary.
–> I want to copy each shown frame into the new ones.
It’s a bit like this “onion” stuff in flash without fading old frames out after a time:

Hope you understand what I am trying to explain.
With kind regards
Johannes
