Sliding a Frame to a New Time in the Clip
Option-clicking a clip with the Time Remap tool enables you to grab the frame at that
point in the Timeline and move it to another time within that clip.
Note: For simplicity, the clip in the following example is described as having timecode
starting at 00:00:00:00, and the Timeline starts at 01:00:00:00. In reality, the source
frame you select corresponds to the timecode value of the captured media file.
For example, suppose you click a 10-second clip at frame 00:00:03:00 and drag that
frame to 01:00:06:00 in the Timeline. A time remapping keyframe appears at frame
00:00:06:00 of your clip.
Frame 00:00:03:00 from the clip’s media file has been remapped to frame 00:00:06:00 in
the clip. A new keyframe is placed at 00:00:06:00, with the left half of your clip being
slowed down and the right half being sped up.
Keyboard Modifiers for Variable Speed Adjustments
Two keyboard modifiers can be used to help you make precise variable speed
changes to a clip using the Time Remap tool:
 To gear down while using the Time Remap tool: Hold down the Command key.
 To snap your time adjustments to 10 percent increments: Hold down the Shift key
after you start dragging.
