Channel Mixer--AE

With this effect, you can modify a color channel using a mix of the current color channels. Use this effect to make creative color adjustments not easily done with the other color adjustment tools, create high-quality grayscale images by choosing the percentage contribution from each color channel, create high-quality sepia-tone or other tinted images, and swap or duplicate channels.

Red, Green, Blue Specifies the contribution of the individual source channel to the output channel.

Constant Specifies the base amount of the input channel to be added to the output channel.

To mix channels in an image:

1 Drag the Channel Mixer effect to the clip.

2 Drag any existing (or source) channel's slider to the left to decrease the channel's contribution to the output channel and to the right to increase it. Or, click an underlined value, type a value between -200% and +200% in the value box, and click OK. Using a negative value inverts the source channel before adding it to the output channel.

3 If desired, drag the slider or type a value for the channel's constant value. This value adds a base amount of a channel to the output channel.

4 If desired, select Monochrome to apply the same settings to all the output channels, creating a color image that contains only gray values.

Monochrome is useful for images that you plan to convert to grayscale. If you select and then deselect this option, you can modify the blend of each channel separately, creating a hand-tinted appearance.
