Join Steve Wright for an in-depth discussion in this video Steve Wright's adaptive despill, part of VFX Keying: Master Course.
- [Instructor] So far, we've seen that no matter…how you adjust the despill,…there'll be some region of the comp…where it just doesn't look right.…So I sat down…with a stack of green screen and blue screen plates,…and developed a more sophisticated approach…to despill that actually adapts to the background image…rather than producing a single color or illuminants.…I call it Adaptive Despill…and I think you're really going to like this.…We'll cruise in.…Starting with our green screen.…Of course we do our obligatory denoise.…
And then we do our despill operation.…Again, it does not matter what you use…because what we want is the spill map.…And we're gonna get that just like in the last video…by subtracting this from the original green screen,…with a merge set to minus,…and there is my spill map.…Next, we'll take that spill map…and shuffle it into all three channels.…And again, we've got spill in the core…and we wanna clear that out…so that we just have the edge spill out here.…
And we're gonna do that with this core mat.…
