A trailer is a promise, not a summary. Its only job is to make someone want the full thing, which means the editing rules that work for the actual video, chronological, complete, balanced, actively work against a trailer. Here is how to build one from raw footage without over-thinking it.
Before touching footage, write one sentence describing what a viewer should feel by the end of the trailer: intrigued, moved, amused, unsettled. Every clip choice gets tested against that sentence. Footage that's technically great but doesn't serve the promise gets cut, and footage that's rough but nails the feeling stays. This is the opposite of how most people start, which is scrubbing through everything looking for "the best shots."
If you're cutting a trailer for a documentary, interview series, or branded film, the strongest trailer moments usually show up as short, quotable lines in the transcript before they show up as visuals: a sentence with a hook, a reveal, an emotional turn, or an unexpected admission. Reading the transcript for these lines first, then pulling the matching footage, is faster than watching hours of raw video hoping something jumps out. A line like "I didn't think I'd make it" or "nobody warned us" reads as a trailer beat on the page well before it's cut into picture.
Act one establishes the world and the stakes at a measured pace, usually the first third of the trailer. Act two accelerates: shorter cuts, rising music, complications stacking on top of each other. Act three peaks just before the resolution and cuts away, deliberately withholding the ending. This pattern shows up across genres because it mirrors how tension actually builds, slow setup, escalating middle, a peak that gets cut short. StudioBinder's breakdown of trailer editing and trailer editor Derek Lieu's analysis of The Matrix as "a trailer editor's dream" both point to the same underlying shape: cuts speed up as the trailer moves toward its final beat, then stop right before payoff.
A team with 40 hours of interview and verite footage for a feature documentary needs a 90-second teaser. Instead of scrubbing all 40 hours, they read the interview transcripts first and mark every line that hits like a trailer beat, roughly 20 lines across six subjects. Those lines get arranged in a rough three-act order directly in the transcript view, slow open, accelerating middle, a held final beat, before any footage is pulled. Only then do they go find the matching shots and build the actual cut, which turns a multi-day scrub into an afternoon.
The biggest mistake is chronological order, cutting the trailer in the same sequence as the footage was shot or as the final piece will play, which almost never matches the tension curve a trailer needs. The second is including too much plot, a trailer that explains the whole story removes the reason to watch it. The third is temp music that never gets swapped, cutting to a placeholder track and never re-timing the cuts once the real score or licensed track goes in, which leaves the pacing feeling slightly off in the final version.
The three-act structure decision, what opens slow, what accelerates, what gets held back, is a story decision, not an editing decision, and it's far faster to make on a transcript than inside an NLE timeline. ScriptCut lets you mark and reorder those trailer-beat lines directly in the transcript, then export the arranged selects as a real XML or EDL timeline into Premiere Pro, DaVinci Resolve, Final Cut Pro, or Avid, so the structural decisions are locked before the editor starts cutting picture.
Decide what you're promising, find the moments that deliver on it, arrange them in a three-act shape that accelerates toward a held final beat, then cut. Doing it in any other order means re-deciding the same structure two or three times before it lands.

Most trailers run 60 to 120 seconds. Long enough to build a three-act tension curve, short enough that every second still earns its place.
A highlight reel shows the best moments in roughly the order they happened. A trailer builds a deliberate tension curve toward a held final beat and withholds the ending on purpose.
Pick a temp track before cutting so pacing lines up with a rhythm, but always re-time the cuts once the real score or licensed track is locked in, since a swapped track rarely lands on the same beats.
Read the transcript first and mark short, quotable lines with a hook, reveal, or emotional turn. Those lines usually read as trailer beats on the page before you ever pull the matching footage.
No. A trailer peaks just before the resolution and cuts away, which is what makes the full piece worth watching.
A three-act shape: a measured opening that sets stakes, an accelerating middle with shorter cuts and rising music, and a peak that cuts away right before payoff.
Cutting in chronological order. A trailer needs a tension curve, not a timeline that matches the order footage was shot or the final piece will play.
