Using the Jog feature

If you need to change the start position of a cued clip, you can jog to the desired frame.

Use the left and right arrow keys to step through 1 frame at a time.
Use Ctrl + the arrow keys to step through 10 frames at a time.
Use Shift + the arrow keys to step through 1 second at a time.
If desired, you may display trim controls by selecting View | Channel Edit Controls and setting a new starting point with the Mark In button.

When you play the clip, the clip starts at the new position.

Note: The X-keys jog/shuttle controller can be used as an alternative to jogging via the keyboard and also allows shuttling of the clip.
