Turn an eect o or on
After adding an eect to a setting, you can turn its properties o or on. This can be useful when
previewing an eect.
m Click the blue activation checkbox next to the eect properties. When the checkbox is blue, the
eect is turned on. When the checkbox is black, the eect is turned o.
Remove an eect from a setting
m Choose a checkmarked item from the Add Video Eect pop-up menu (at the bottom of the
Video inspector) or the Add Audio Eect pop-up menu (at the bottom of the Audio Inspector).
The eect’s properties are removed from the list below the pop-up menu.
Video eects
Choose a video eect from the Add Video Eect pop-up menu in the Video inspector:
•
Black/White Restore: Compresses the solid black and white areas (luminance) in the video, such
as backgrounds. This eect can restore nearly black colors to pure black and restore nearly
white colors to pure white without aecting colors in the rest of the image. Drag the sliders to
set the black and white values between 0 and 100. (You can also double-click the values and
type new values.)
•
Brightness and Contrast: Brightens or darkens the overall color and luminance of the video. For
example, use this eect to counteract the darkening to video that some QuickTime codecs can
cause. It’s recommended that you avoid extreme settings, because they can make colors look
washed-out. Drag the sliders to set brightness and contrast values between –100 and 100. (You
can also double-click the values and type new values.)
•
Color Correct Highlights, Color Correct Midtowns, Color Correct Shadows: Correct white balance
inaccuracies and create color eects on the bright, midtone, or dark areas of the video. Drag
the sliders to set red, green, and blue values between –100 and 100. (You can also double-click
the values and type new values.)
•
Fade In/Out: Adds a dissolve and a matte color at the beginning and end of the clip. This eect
has the following properties:
•
Fade in duration/Fade out duration: Enter a time (use a decimal to specify tenths of seconds)
in the text eld to set the duration of the fade-in and fade-out eects.
•
Fade in opacity/Fade out opacity: Drag the sliders to set the opacity of the clip’s video at the
rst and last frames. (You can also double-click the values and type new values.) A value of
0.0 sets the clip video to be completely covered by the matte color; a value of 0.5 sets the
clip to be 50 percent covered by the matte color; and so on.
•
Fade color: Click the color well to set the fade-in and fade-out color.
•
Gamma Correction: Controls the range of brightness in an image. This eect can be used to
remove detail from an underexposed clip or to reduce the saturation of an overexposed clip.
Drag the slider to set gamma values between 0.1 and 4.0. (You can also double-click the value
and type a new value.)
Note: Computers using dierent operating systems have dierent monitor settings. For cross-
platform viewing, correcting the gamma will improve the image for all platforms.
