hard edge on glow

Question

I screen recorded my issue here: probably the clearest way to see the problem: https://vimeo.com/928095854/7cf75b44e7?share=copy

With words: I am simply dropping the stock Dissolve - vapor effect on some PNG's. I've done it many times in other projects with no issues. This time, the glow it creates is HUGE and I can't rid of a weird hard edge on that occurs on the edge of the PNG. I have already tried enlarging both the PNG and the comp quite a lot. There is room in the comp for the glow to keep extending past the edge of the PNG, not sure why it won't.

Thanks in advance.

Simply looks like you underestimate how even 0.01 % opacities can add up and produce visible artifacts and the way that particular preset creates the faux glow doesn't help due to CC Composite's limitations. Or in other words: You are using the effect in a way it probably was never meant to be used. Most of those presets are just quick&dirty text treatments. It would probably be the best to build the glows in a "clean" manner underneath the actual footage and then you can play around with blending modes , tint the contours and blur them or whatever.
