043 Roto node edge feathering

- [Steve] Hi, this is Steve Wright,…welcoming you to this week's Nuke Nuggets,…a close look at the Roto Node Feather falloff control.…The Roto Node gives you tremendous control…over the lick of the feathered edges of a Roto.…Here we'll take an inside look…at the four falloff types and the falloff slider…to see what the various feathers look like…and their final effect on the edges of your comp.…I'll select my shape here to light up falloff type.…Now we're talking about the four falloff types right here.…

By default, we'll look at the first one which is linear.…I set up a sampler node so that I can show you, sample,…exactly what the falloff looks like,…and of course the linear falloff is perfectly linear.…This up here is the edge of my shape.…Then the falloff is linear…until we get to the edge of the feather.…So the edge of the feather's down here,…the edge of the shape is up there.…Now the linear gives you a hard edge…at both the shape and the feather.…

So we look in the viewer,…we're looking at the alpha channel,…
