Final answer:
In Shuffle mode, deleting a clip causes subsequent clips to automatically shuffle back to close the gap, whereas in Slip mode, the remaining clips stay in place, leaving an empty space.
Step-by-step explanation:
When you delete a clip from between two existing clips in Shuffle mode, the clips that come after the deleted clip automatically shuffle back to fill the gap, ensuring there are no empty spaces between clips. This mode is useful for maintaining the sequence of clips without having to manually close gaps. In contrast, when you perform the same action in Slip mode, the subsequent clips do not move; the deleted clip leaves behind an empty gap, and the remaining clips preserve their original positions in the timeline. This mode provides precise control over clip placement, which can be critical for tasks like audio editing, where maintaining exact timing and positioning is essential.
