As you would normally, select the segment of the clip you want using the brackets ( { } ) and insert the clip into your sequence using the insert button (six buttons over from the right bracket button).

Once the clip has been imported, go to the upper left and click on the “Effect Controls” tab. This tab is to the left of the tab that holds all of your imported clips. If there is no “Effect Controls” tab, go to the top of your screen and click “Window” and then “Effect Controls”.

The “Effect Controls” box should be empty. Select the clip within your sequence that you wish to make black and white. A list of already implemented audio and video effects will appear.

Go to the bottom left of your screen to the “Effects” box where different effect options are listed. Click on “Video Effects”.

Under “Video Effects” is a long list of various effects. Click on “Color Correction”. Another list will appear.

Find “Channel Mixer” in the list of effects under “Color Correction”. Drag and drop the title into the above “Effect Controls” box.

Click on “Channel Mixer” within the “Effect Controls” box. A list will appear.

Scroll to the bottom of the list to where it says “Monochr…” (Monochrome). Click on the box to the left of that to check the box, causing the video in your “Program” box (the box that shows your end result in the upper right) to turn black and white.

If you need to adjust the levels of black, white and gray in the video, scroll back to the top of the “Channel Mixer” list and adjust the various color levels (Red-Red, Red-Green, Red-Blue, etc.). To do that, click and hold on the blue number adjacent to each color level and drag your mouse left or right to adjust the levels.
