Apple Final Cut Pro 7 - Manual (Page 1157)

2 In the speed indicator area, drag a speed keyframe to the left or to the right.
The tick marks in the speed indicator area update in real time as you drag the keyframe,
showing you exactly how you’re altering a clip’s timing. The spacing and color of the tick
marks indicate the speed and playback direction of your clips. Large spaces between tick
marks indicate slow motion. Tightly spaced tick marks indicate fast motion. The red color
indicates reverse motion.
Tip: Optionally, hold down the Shift key as you drag to push or pull all trailing keyframes
in the clip item at the same time.
Keep the following points in mind when you use speed keyframes and speed segments:
• Any change you make to an individual speed keyframe will alter the segments to the
left and right of the keyframe, but it will leave all other speed segments unchanged.
• If maintaining video and audio sync is a priority, select both the video and the (synced)
audio and apply constant speed changes only. Applying variable speed settings to a
video clip (including speed segments, the Curve buttons in the Change Speed dialogs,
and the Curve options in the Change Speed shortcut menu) will break the link to audio
items. Audio and video sync is lost when you apply variable speed changes.
Adjusting Speed Segments with the Shortcut Menu
You can use the shortcut menu to adjust the speed in a particular speed segment (the
area between two speed keyframes) or in a speed keyframe.
To adjust a speed segment with the shortcut menu
1 If there is no existing speed keyframe in the Timeline, add one.
2 Control-click a speed segment (the area between two speed keyframes).
3 Choose any of the following from the resulting shortcut menu.
• Change Speed: Opens the Change Speed dialog. For more information, see “Using the
Change Speed Dialogs.”
