222 Part II Project Interchange
The amount of blur that appears in either case depends on the speed of the moving
subject. The faster the subject moves, the more blurred it becomes, similar to a motion
picture film or video image. The amount of blur that is added can be modified using
two parameters.
 % Blur: Affects the smoothness of the motion blur. 1000% blurs over 10 frames; 100%
blurs on one frame.
 Samples: Determines the detail of the applied motion blur, which is dependent upon
the speed of the motion effects applied to a clip. Additional samples appear as
additional layers of blurring. To change the number of samples, choose a number in
the Samples pop-up menu.
∏
Tip: Motion blur can also be used to soften the strobing effect that may appear in clips
with extremely slow motion applied to them.
Time Remap Parameters
Time remapping allows you to alter the speed of a clip to create either constant or
variable speed fast- or slow-motion effects. You can apply constant speed changes or
variable speed changes. Applying a constant speed change to a clip alters the entire
clip’s playback speed by the same percentage. Applying variable speed to a clip allows
you to dynamically alter the speed of a clip, making a clip alternate between a range of
speeds, throughout any duration you specify. You can also reverse the speed of a clip,
making it play backward. For a detailed description of the Time Remap parameters, see
“
Time Remapping in the Motion Tab ” on page 332.
Using the Paste Attributes Command
As you composite multiple clips together in Final Cut Pro, it’s important to take
advantage of whatever shortcuts you can to eliminate steps and save time.
The Paste Attributes command in the Edit menu (keyboard shortcut Option-V) is a
valuable tool for selectively copying attributes from one clip to another without
having to open clips into the Viewer. It also eliminates the need to repeat steps when
applying identical effects to multiple clips. For detailed information about this
command, see “
Copying and Pasting Specific Clip Attributes ” on page 287.
Note: The examples starting on page 225 show how you can use the Paste Attributes
command when compositing clips and creating motion effects.
