What does nesting a sequence mean in Premiere Pro?

Nesting a sequence in Premiere Pro refers to the process of combining multiple clips or sequences into a single sequence. This technique is particularly useful for organizing complex projects where multiple edits, effects, or transitions are applied. When sequences are nested, they can be treated as a single clip, which simplifies the timeline and allows for easier adjustments.

For instance, if you have a series of clips that you've already edited and you want to apply a uniform effect or transition to them as a whole, nesting them enables you to manipulate them together without affecting the individual edits within the nested sequence. This promotes a cleaner and more efficient workflow, especially in projects with intricate timelines.

The other choices do not accurately represent the definition of nesting within the context of Premiere Pro. Creating a backup of the project and saving sequences in a folder pertain to project organization rather than the specific functionality of nesting sequences. Removing clips from the timeline involves a different action entirely and does not relate to the concept of combining clips or sequences.
