84 Part II Learning About the Final Cut Pro Interface

Â RGB, Alpha, or Alpha+RGB: When you’re compositing, it can sometimes be handy to

have a quick look at the alpha channel of your clip. The alpha channel defines areas

of transparency, and can change if various filters are applied. Viewing your sequence

with the Alpha or Alpha+RGB option selected shows you exactly which areas of your

image have transparency. Additional controls are available for viewing the individual

Red, Green, and Blue channels in the View menu.

Important: If the image display area in the Viewer is all black or all white, it may be

because the Canvas is set to view only the alpha channel instead of the RGB

channels. Try changing the channel view to RGB to solve this problem.

Â Black, White, Checkerboard: When working with clips that have an alpha channel, you

can choose different backgrounds to make it easier to see which areas of your

picture are transparent. For example, translucent clips or generated text may be

more visible if you choose a background that emphasizes them, such as

Checkerboard 1 or 2. You can also view Red, Green, and Blue background colors

using the View menu.

None of these view options affect either rendered output or material sent to tape. They

only affect display in Final Cut Pro.

Playhead Sync Pop-Up Menu

You can lock the Viewer playhead to the Canvas/Timeline playhead so that they move

together while scrubbing through clips.

Note: This menu also appears in the Canvas, and the options are the same.
