Join Steve Wright for an in-depth discussion in this video Uber key with the additive keyer, part of VFX Keying: Master Course.
- [Instructor] In this video,…we'll look at the workflow when using an Additive Keyer…with an Uberkey.…How to build an Additive Keyer…was covered in detail in Chapter six…so here we'll have just a quick review.…So let's start with just a very quick overview…of our Uberkey, again, the green screen and the Denoise.…From here, we pull the soft key with Keylight,…which of course we got some noise out here in the backing…and a lack of solid core.…So from there, just did the usual dilate and firming up,…and use that with a multiply to clean the backing region.…
So this is before, oh, let me gamma up the Viewer…so that's before and that's after the Garbage Matte.…Okay, so addressing our flaky core,…on a separate branch used Primatte,…my favorite heavy core keyer, and did the usual Blurs,…and Grades, and Erodes, and Blurs…to create a inner core matte and we did a union.…So now if we toggle that on and off…we can see the effectiveness of the core matte…and, again, we want…to make sure we're not expanding our edges anywhere.…
