Join Steve Wright for an in-depth discussion in this video Stack IBKColor nodes for cleaner clean plates, part of VFX Keying: Master Course.
- Our clean plate requirements for screen correction…are just to build the edge regions…and not make a totally clean plate.…However, if you do want to…make a totally clean plate for some reason,…you might get better results…by stacking the IBK color nodes.…So, we'll start with this two K badly vignetted here,…gamma down the viewer so you can see…my corners are really bad.…So, I really need a clean plate for this guy…if I want to do screen correction.…So, we'll start by attaching an IBK color node here.…
We'll of course set it for green.…I'll drop the size down to like four,…as an opening gambit,…maybe even touch up the erode to two…before I even begin dialing.…So let's go dialing for colors here.…So I'm gonna raise my dark reds…until I decay the outer perimeter.…So I'll back off.…I'll raise the greens,…that goes the wrong way so let me go the other way.…That's not helping so I'll put that back.…
Try the blue…and that quickly derodes my corners, alright.…So let's switch over to the lights…and see if we have better luck here.…
