Channels pop-up menu
The Channels pop-up menu (the color spectrum icon) controls which color channels are
displayed in the Canvas. Use this menu to view a single color channel in the Canvas, to examine
layers’ alpha channels, or to manipulate effects that affect only a single color channel. This menu
has the following options:
•
Color: Shows the image as it would appear on a video monitor. Visible layers appear in natural
color and transparent areas reveal the background color as set in the Properties Inspector for
the project. The background color is black by default. To change it, press Command-J, then
choose a color from the Background Color control in the Properties Inspector.
Note: The Background pop-up menu in the Properties Inspector must be set to Solid to export
the background color with the project. This option creates a solid alpha channel on export
(when exporting using a codec that supports alpha channels). When the Background pop-up
menu is set to Transparent, the color is visible in the Canvas, but does not render as part of the
alpha channel.
•
Transparent: Shows the background area of the Canvas as transparent. A checkerboard pattern
appears by default where no images block the background.
•
Alpha Overlay: Displays the image in normal color, but adds a red highlight over transparent
areas of the image.
•
RGB Only: Displays the normal mix of red, green, and blue channels but displays transparent
areas (including semitransparent areas) as opaque.
•
Red: Displays only the red channel as a range of black to white.
•
Green: Displays only the green channel as a range of black to white.
•
Blue: Displays only the blue channel as a range of black to white.
•
Alpha: Displays the alpha (transparency) channel of the layers in the Canvas.
•
Inverted Alpha: Displays an inverted view of the alpha (transparency) channel.
Render menu
The Render pop-up menu controls the quality and resolution of the Canvas display and lets you
enable or disable features that can impact playback performance. When an option is active, a
checkmark appears beside the menu item. If a complex project is causing your computer to
play at a very low frame rate, you can make changes in this menu to reduce the strain on the
processor. This frees you from waiting for the image to be rendered at full resolution each time
you make an adjustment, allowing you to watch complex projects at high frame rates while
you work.
The Render pop-up menu displays the following items:
•
Dynamic: Reduces the quality of the image displayed in the Canvas during playback or
scrubbing in the Timeline or mini-Timeline, allowing for faster feedback. Also reduces the
quality of an image as it is modified in the Canvas. When playback or scrubbing is stopped,
or the modification is completed in the Canvas, the image quality is restored (based on the
Quality and Resolution settings for the project).
•
Full: Displays the Canvas at full resolution (Shift-Q).
•
Half: Displays the Canvas at half resolution.
•
Quarter: Displays the Canvas at one-quarter resolution.
•
Draft: Renders objects in the Canvas at a lower quality to allow optimal project interactivity.
There is no antialiasing.
