How to Write a Video Hook (First 3 Seconds)

A video hook is the first line of your video. It runs in the first 3 seconds. Its only job is to stop the scroll.

Write it well and people watch. Write it badly and they swipe away. The rest of your video never gets a chance.

This guide gives you six hook formulas. Each one comes with an example. Then you will learn how to test hooks fast.

Why the hook decides if people watch

People scroll fast. They judge your video in a blink. Most decide before second three.

Your script can be great. Your editing can be sharp. None of it matters if the hook fails.

So the hook is your most important line. It earns the next 30 seconds. Spend real time on it.

A weak hook costs you views. It also costs you reach. Platforms push videos that hold attention. The hook starts that chain.

What makes a strong hook?

A strong hook is short. It says one clear thing. It speaks to one person.

It also creates tension. The viewer feels they must keep watching. That pull is the whole game.

Keep these rules in mind:

• One idea per hook.
• Use simple words.
• Lead with the most interesting part.
• Talk to "you," not "everyone."
• Cut every word you can.

Now let's build hooks you can use today.

How do you write a question hook?

Ask a question your viewer wants answered. The question opens a loop in their head. They watch to close it.

Make it specific. A vague question gets a shrug. A sharp question gets a click.

Examples:

• "Why do your ads stop working after a week?"
• "What if you could film a video without a camera?"
• "Are you wasting money on the wrong hook?"

How do you write a bold claim hook?

State something strong and clear. Sound sure of it. Confidence pulls people in.

Back it up later in the video. The claim earns the watch. The proof keeps it.

Examples:

• "Most video ads fail in the first second."
• "You don't need a film crew anymore."
• "This one line tripled my watch time."

How do you write a problem hook?

Name the pain your viewer feels. Say it out loud. They feel seen and they stay.

Pick a real, daily problem. The closer to home, the better.

Examples:

• "You write a script, then go blank on camera."
• "Your videos look fine but nobody finishes them."
• "Filming takes hours you don't have."

How do you write a curiosity gap hook?

Tease an answer but hold it back. Show there is a payoff coming. Then make them wait for it.

Don't trick people. The payoff must be real. A fake gap kills trust fast.

Examples:

• "There's one reason your hooks flop. It's not what you think."
• "I changed three words and views doubled."
• "Most creators miss this simple fix."

How do you write a pattern interrupt hook?

Break the expected flow. Do or say something odd. The surprise stops the thumb.

It can be a strange line. It can be a quick visual jolt. Surprise buys you attention.

Examples:

• "Stop. Delete that video right now."
• "I deleted my best-performing ad. Here's why."
• "Nobody told me this, so I'm telling you."

How do you write a result-first hook?

Lead with the outcome. Show the win before the how. People want the result fast.

Then explain the steps after. The result is the bait. The method is the meal.

Examples:

• "Here's how I made 50 videos in one weekend."
• "This script got 100,000 views. Let me break it down."
• "Zero budget, one tool, full ad campaign."

How to test your hooks fast

Don't guess which hook wins. Test it. Your gut is often wrong.

The trick is volume. Write many hooks, not one. Then compare them with real viewers.

Here is a simple loop:

1. Write five hooks for the same video.
2. Use a different formula for each.
3. Make a quick version of each one.
4. Post or share them.
5. Keep the hook that holds attention.

Doing this by hand is slow. That is where AI helps.
