In this third tutorial in a set of four on basic multi-layered keying in Adobe After Effects using Keylight 1.2, Andrew Devis shows how to deal with a specific problem that can occur with some keyed footage, namely that of strong lines appearing on some edges of the keyed footage. In this tutorial, Andrew shows how to select the areas with problems while still maintaining a good over all matte through the use of other layers.

Hi Frank

The concept is that you have a core matte which is the one that you would have applied an animated mask to if that were needed (which it wasn't in this case). You would then pre-compose that layer and use that for all your following layers.

As for using adjustment layers, the reason I use multiple copies of the core matte is to have all the keylight tools on each layer I use.

Hope this helps

Good tutorial and interesting workflow. But I am confused about the concept using a base and a core layer. Wouldn´t be one layer enough to fill up the missing pixels beneath. Also you could use an masked adjustmentlayer for the edges to reduce the layers.

I forgot to mention that you can set the layer blendmode to "alpha add" so you won´t need a base layer to replace those missing pixels.

In this first of 4 tutorials on basic multi-layer keying in Adobe After Effects using Keylight 1.2, Andrew Devis starts by showing how and explaining why you might need a garbage matte for most keying work and what considerations are important for such a matte. Andrew then goes on to show how to pull a basic key and then modify that key to ensure that you don't over-smooth your end results, finally viewing the keyed footage with a bright image behind to test the key.

In the second of 4 tutorials on basic multi-layered keying in Adobe After Effects using Keylight 1.2, Andrew Devis shows how to deal with light spill issues on separate parts of the keyed footage. Sometimes when you pull a key you have problems with light spill that cannot be resolved with a single key. In this tutorial, Andrew shows how to start to create multiple keys and layer them on top of each other for excellent results.

What Are Adobe Motion Graphics Templates?

What Are Adobe Motion Graphics Templates?

A Motion Graphics Template, referred to as a MOGRT, is an animated sequence that is self-contained and can be used in Adobe Premiere Pro, Adobe Premiere Rush and Adobe After Effects, combining graphics, text, audio and video files, as well as vector or still images (including logos), to create a still or animation that can then be customized by the MOGRT user. The result is a dynamic creative tool that provides design freedom and is consistent to its users across apps and devices. Reuse, share, and even sell them!
