Let’s start!

【No.08-03】【After Effects】[Beginner] HOW TO USE KEYING EFFECT

One of the methods of combination is to select a specific color from the material and remove only that color. This is called “keying”.

It is generally used to combine the blue background and the green background materials.

Linear color key

Apply Keying Effect

Place the material you want to remove a specific color in the timeline. Here I will use green background material. This green part will be extracted with the Keying effect!

Effect& Presets panel -> Keying > apply Linear Color Key to the layer of the green background material.

The Linear color key effect has been added to the Effect Controls panel.

Next, use the Key color to specify the color to be extracted.

Use the pointer to specify the color you want to remove from the Preview panel. This time, it’s green background material, so the green part is designated as the key color.

The specified color was extracted!

Adjust Keying

If the color is not extracted well, make fine adjustments from the Effect Controls panel.

Matching allowance allows you to specify the approximate color range. If other colors are included, increase the tolerance and you can extract them well.

If you increase the tolerance too much, you will extract the parts you don’t want to extract like this.

If the border of the material you extract is rough, increase the flexibility of matching and soften the border.

Keylight

Use the Keylight effect for more advanced keying! Basic operation is similar to Linear color key.

Extract

There is also a way to combine using the brightness of the material.

This color bar is used as a material.

First, apply [Keying] ->[Extract] to the material.

The Extract effect is displayed on the Effect Controls panel like this.

Let’s try increasing the value of Black point!

If you increase the Black Point value, the dark part will be removed from the material.

Then try lowering the value of White Point!

If you lower the White Point value, the bright part will be removed from the material.

This is the end of the lecture on how to use Keying effect!
