Join Steve Wright for an in-depth discussion in this video Uber key with split soft key and split despill, part of VFX Keying: Master Course.
- [Narrator] Keyers often fail…to key all parts of the target equally well,…so in those situations,…it's necessary to pull two or more keys…and merge them together.…The same thing can happen with spill suppression,…where just one part of the target has problems.…So again, two or more despill operations may be needed.…Here we see how to join…those multiple efforts together…into a single uberkey, and a unified, despilled image.…So let's cruise in here…and start by taking a look at our split soft key.…
Here at the main key, we switch to the alpha channel,…we can see that we've got some noise out here,…and of course we have our transparency problems here,…but the real thing that we want…is some better hair detail.…We can see here that the hair detail…has frankly been clobbered by our denoise routine.…The problem is that light bits of hair…are down literally in the noise level,…so the denoise or degrain routine…can remove the fine hair details,…but having it denoised or degrained…is extremely helpful for getting a good key in general.…
