I have often contemplated writing an article that looks at how different ke= ying plugins work, there are a few basic approaches.=C2=A0 Keylight is my g= o-to plugin because it comes with AE, however the last time I had to do key= ing I was very surprised to discover that I got better results with the old= AE 8-bit =E2=80=9CColor Range=E2=80=9D keyer than with Keylight.=C2=A0 Go = figure=E2=80=A6 I will experiment more with this in the future.=C2=A0 I fin= d Keylight crashes constantly with AE 2017, which is why I have been trying= alternatives.

Primatte works in a totally different way to Keylight, so they are likely t= o give different results with different footage.=C2=A0 Keylight is a differ= ence keyer, and works by looking at the difference between the Red, Green &= amp; Blue channels.=C2=A0 A more advanced version of putting a green solid = on top of your footage and choosing the difference blending mode.=C2=A0 Thi= s is why it only really works with green or blue screens.

Primatte is an advanced linear keyer, although I recall their marketing usi= ng the term 3D keyer (maybe I=E2=80=99m remembering incorrectly).=C2=A0 Bas= ically, imagine an RGB value plotted on a graph as an X,Y,Z co-ordinate.=C2= =A0 Every colour will have a different position in a cube where the axis ar= e represented by R,G,B values.=C2=A0 Primatte compares the position of each= pixel with the position of the main key colour, as if they are co-ordinate= s in 3D space, and uses the distance and direction to calculate if the pixe= l is transparent or not.

Always fun to discover what=E2=80=99s happening under the hood=E2=80=A6
