Mix color channels in a clip

  1. In the Effects panel, click the triangle to expand the Video Effects bin, and then click the triangle to expand the Adjust bin.
  2. Drag the Channel Mixer effect to the clip in a Timeline panel.
    Note: If the clip is already selected in a Timeline panel, you can drag the Channel Mixer effect to the Video Effects section of the Effect Controls panel.
  3. Decrease or increase a channel’s contribution to the output channel by doing any of the following to a source color channel:

    • Scrub an underlined value to the left or right.

    • Click an underlined value, type a value between –200% and +200% in the value box, and press Enter (Windows) or Return (Mac OS).

    • Click the triangle to expand the Channel Mixer controls, and drag the slider to the left or right.

  4. (Optional) Drag the slider, scrub the underlined text, or type a value for the channel’s constant value (Red‑Const, Green‑Const, or Blue‑Const). This value adds a base amount of a channel to the output channel.
  5. (Optional) Select the Monochrome option to create an image containing only gray values. This option achieves this result by applying the same settings to all the output channels.
