Struggling to create a documentary trailer that stands out? You’re not alone. Many filmmakers face the challenge of condensing hours of footage into a compelling 90-second story that pulls viewers in. The right trailer can be the difference between your film reaching its audience or fading into the background. In this guide, you’ll learn how to craft a trailer that grabs attention and keeps people wanting more.

Prepare Before You Edit


Select Your Best Footage

Start by picking the strongest moments. Focus on key plot points, impactful scenes, and visually stunning shots. Only the best of the best should make it into the trailer.

In the Eagle Huntress, the trailer opens with breathtaking shots of the Mongolian landscape and talking about the ancient tradition of eagle hunters, instantly capturing the essence of the story.

Choose Music Carefully

Music isn’t just background—it drives the emotion of your trailer. Pick tracks that fit the tone of your film, whether it’s dramatic, hopeful, or tense. Even a placeholder track can help you find the right feel.

Structure Your Trailer in Five Key Sections

1. The Hook (0-10 Seconds)

  • Grab Attention Immediately: The first 10 seconds are crucial. Use a surprising statement, question, or striking visual to make viewers stop and watch.
  • In the trailer for Free Solo, the first few seconds show Alex Honnoldwalking towards the incrediblesteep cliff face of El Capitan and talking about climbing it with no rope. It’s visually stunning and terrifying, instantly gripping the audience.
  • Know Your Audience: Tailor your hook based on who you want to reach—whether it’s festival judges, potential funders, or a general audience.

2. Introduction

  • Introduce the Premise:Clearly show what your documentary is about in under 20 seconds. Set the context and establish the stakes.
  • In the trailer for the documentary Won't You Be My Neighborwe're introduced to the gentle but profound influence of Fred Rogers in the first 30 seconds, showing clips from his iconic show and setting the emotional tone of the film.
  • Build Credibility: Use key figures, news clips, or strong visuals to establish why your story matters.

3. Rising Tension (30-60 Seconds)

  • Show the Conflict: Introduce the core problem. Highlight main challenges or conflicts to build interest and emotion.
  • In Icarus, the trailer shows a sequence of mysterious, high-stakes events that lead to uncovering a massive doping scandal, building tension and curiosity.
  • Escalate the Drama: Show footage that raises the stakes. Make viewers feel the urgency of the situation.

4. Climax (60-80 Seconds)

  • Reach the Peak: This is where the tension hits its highest point. Let the music swell and the visuals intensify.
  • In the trailer for Blackfish, ituses fast cuts of whales thrashing and interviews with emotional former trainers. It shows the intensity of the conflict without giving away the resolution.
  • Keep It Vague: Don’t give away the resolution. Leave viewers wondering how things will turn out.

5. Outro (80-90 Seconds)

  • Bring It Full Circle: Reference your hook. Reflect, but don’t resolve everything—leave some questions unanswered.
  • The trailer for The Cove ends with shots of hidden cameras and a voice, like a panicked radio transmission, urgently saying, "Get out of there, get out of there now." This implies danger and suggests they've been discovered, creating intrigue and compelling the audience to watch the documentary to see what unfolds.
  • Call to Action: Tell viewers what to do next—visit your website, watch the full documentary in theatres/online, or share it. Make it easy for them to stay engaged.

Tips for Refining Your Trailer

  • Edit to Music: Sync your cuts to the rhythm of the music. This keeps the trailer engaging and gives it a natural flow.
  • Keep It Short: Stick to 60-90 seconds. It’s a teaser, not a summary. Every moment should add value and build toward the climax.
  • Test It: Show your trailer to others who haven’t seen the documentary. Pay attention to their reactions—do they look hooked? Use their feedback to refine and improve.
