Harry Potter Effect
I've created a priori incantatem on a separate composite tab. The background used in that tab was a black plane. I've been able to make the particles in the effect glow using a grade, which works perfectly with the black background. But, when I add my clip in, the grade causes the entire shot to become overexposed. How do I keep the particles glowing without it effecting the rest of the clip? Is there a way to make the clip unaffected by the grade?
