Final Cut Pro: How To Use the Change Speed Dialogs
With the Change Speed dialogs, you are able to apply speed effects to your clips, such as slow motion and fast motion. The Change Speed dialog also allows you to change the speed of a clip over a specified period of time. The Change speed command is located in the Modify menu.
Changing Speed Dialog Controls
Before you can begin using the Change Speed dialog, you need to understand what the basic controls do. The Duration field allows you to enter a new duration for the clip you are editing. The Rate field allows you to change the speed of a clip by entering a percentage. If you enter 100%, the speed will not change. Percentages over 100% create fast motion and percentages under 100% create slow motion.
The Original field cannot be edited. It simply displays the duration of the clip before you edited it using the Duration field. The Reverse checkbox allows you to play the clip you are editing in reverse. The clip will play using the speed that you enter in the Rate field. The Start and End buttons allow you to change the rate of speed at the beginning and end of a clip or speed segment.
The Ripple Sequence checkbox enables automatic rippling of the clip you are editing. You can only use the Ripple Sequence checkbox if you have adjusted the speed and/or duration of a clip. The Scale Attributes checkbox will scale time-based attributes, such as keyframes and markers. The Frame Blending checkbox is used only for clips that are being played in slow motion. By using Frame Blending, Final Cut Pro will smooth out the motion of the clip.
Changing the Speed of an Entire Clip
To use the Change Speed dialog to change the speed of an entire clip, you need to have the clip opened in either the Browser or Timeline. You will then go into the Modify menu and select Change Speed. You can also open the Change Speed command by pressing Command and J. When the Change Speed menu opens, you will be able to use any of the controls that you wish to. When you press OK, the changes that you made will be applied to your clip.
Changing the Speed of an Individual Segment
You can also use the Change Speed dialog to change the speed of an individual segment. The clip that you wish to edit must be opened in the Timeline and at least one speed keyframe must be applied. You will then need to display the keyframe graph area and the speed indicator tick marks. This can be done by pressing Option + T. Once those values have been displayed, Control-click on the individual speed segment that you wish to change. When the shortcut menu appears, click on Change Speed Segment and the dialog will appear. From that dialog, you will be able to use any of the controls that you wish to. When you press OK, the changes that you made will only be applied to that specific speed segment.Popular Lenses:
