Join Steve Wright for an in-depth discussion in this video Screen correction with adaptive despill, part of VFX Keying: Master Course.
- [Instructor] In this video,…we'll look at using screen correction…with my adaptive despill technique.…This combination works especially well…since the uniform backing from the screen correction…makes the adaptive despill work even better.…So let's take a quick cruise…up here at the screen correction.…Now we've done this before, in Chapter Two:…Pre-processing the green screen,…we have several tutorials on this.…But I just wanted to show you…that even though this is…an unusually uniform green screen,…the adaptive despill…actually is doing a little bit of repair,…even on a screen as good as this.…
Here, let me dial in my viewer gamma for you here.…So you can see in the original green screen,…this area's kinda dark and you have a little seam there,…but when I switch to the screen correction…the defect goes away.…So this whole area is gonna turn the background dark…if we don't do something about it.…Alright, so viewer back to normal.…So that is our lovely screen correction right here.…Now we follow that…up here, over there, and down to here,…
