Cross-Cutting, also known as parallel editing, is an editing technique in which two or more separate actions taking place in different locations or timelines are intercut with one another, creating the impression that they are happening simultaneously or in relationship to each other. It is one of the foundational techniques of narrative film editing and is used to build tension, establish connections, and compress time.

The technique allows filmmakers to show multiple storylines unfolding at once, cutting back and forth between them to maintain momentum and build suspense. Classic uses include chase sequences where the pursuer and the pursued are shown in alternating shots, countdowns where multiple characters race against the same deadline from different locations, and phone conversations where both sides of the call are visible. Cross-cutting can also be used for thematic or emotional juxtaposition, showing contrasting situations that comment on each other without being directly connected in time or space.

In AI video generation workflows, cross-cutting requires creators to generate footage of each parallel action separately and then assemble them in post-production through editing. Understanding the grammar of cross-cutting helps creators plan their generations more effectively, ensuring that each generated sequence has the visual coherence, pacing, and emotional tone needed to function when intercut with the others in the final edit.
