To move a clip to another track while keeping its horizontal position in a
sequence the same:
1 In the Timeline, select the clip you want to move.
2 Press the Shift key while dragging it vertically to the new track.
The clip will be at the same timecode location, but on another track.
Moving Clips Numerically
When you want to move clip items precisely, you can move them by entering positive
or negative timecode values.
To move an item by entering a timecode value:
1 In the Timeline, select the clip item or items you want to move.
2 Type a relative timecode value for where you want the clip to be positioned.
For example, type +48 (or simply 48) to move the item 48 frames forward. To move 48
frames backward in time, type –48. When you type a number, a Move field appears
above the track. You can also type a regular timecode value to move the clip to that
location in the Timeline.
Note: Don’t click in the Current Timecode field before you do this, or you’ll move the
playhead instead.
