30–90 second recap from prior episode, cut at series start — refreshes viewer memory without eating runtime. Archive footage montage.
You're in the edit suite, Episode 5 is in front of you, and your editor asks: Do we need a "Previously on"? The answer depends on how much your viewers have forgotten — and honestly: they forget more than you think. Days, weeks, or months pass between episodes. The emotional context of the last cliffhanger is gone. Storylines blur. A well-edited recap of 45–90 seconds using existing material solves the problem without wasting precious time on exposition in the new episode.
The craftsmanship is trickier than it looks. You work exclusively with archival material — scenes from previous episodes, not newly shot. The material has different lighting values, different camera characteristics, possibly different color temperatures. Your job is to arrange these snippets so they form a clear narrative logic: Who are the players? Which conflict is escalating? Which decision drives the episode forward? The editing sequence must build tension, not just string scenes together. A good recap has rhythm — quick cuts for action-packed moments, longer holds for emotional beats. Music helps: often a teaser track plays underneath, signaling urgency.
Practically: Look at which scenes are thematically central. A love scene that later leads to drama — yes. A minor character's joke — no. You filter for essence. Keep chronology in mind, but not rigidly — you can mix scenes from different episodes if they form a coherent storyline. Color grading helps smooth out jumps. Sometimes you need fades or dissolves between historically distant scenes to signal continuity.
A common mistake: The recap becomes too long or too dense. Viewers don't want to strain to remember details — they want to get that "Ah yes, that's why this is happening now" feeling. Short, concise, with one or two clear emotional anchor points. And technically: Make sure audio cuts are clean. Cutting off dialogue mid-sentence is much more jarring than in a regular edit because the viewer is consciously aware of the archival material.
