how to write a hook for a reel: the first frame and the first line

Most of the reels I'm asked to rescue were lost before the second sentence. The idea was fine, the filming was fine, and then the video opened on a logo, a "hey everyone" and a slow pan across a shop counter, and the viewer was gone. Learning how to write a hook for a reel is mostly learning that the opening has two jobs, and that most people only do one of them.

I write hooks and scripts for the brands I edit for, and the hook is the part I rewrite most. This guide covers why the opening matters so much on Instagram in particular, the two parts of every hook, a five-step way to write one, before-and-after rewrites, and how to check whether a hook worked. I'm the vendor here (I script and edit reels for a living), so weight my opinion accordingly. Platform and research claims link to their sources; the rest is my experience, labelled as such.

why the first three seconds carry the whole reel

Instagram is unusually open about what it ranks reels on. Its own page, Instagram Ranking Explained, says the most important predictions it makes are how likely you are to reshare a reel, watch it all the way through, like it, and go to its audio page. The same page says that, much like Explore, most of the reels a person sees come from accounts they don't follow.

So assume the person watching doesn't know you. Nobody watches to the end of something they skipped in the first moment, and a stranger owes you nothing, so the opening has to earn the next ten seconds on its own.

Instagram now measures that moment directly. In August 2025 its @creators account announced a retention chart for reel insights, and Social Media Today quoted Instagram defining the new skip rate metric as the percentage of views from people who skipped the reel during the first 3 seconds. That number is, in effect, a score for your hook.

a reel hook is two hooks: the first frame and the first line

When people talk about hooks they usually mean the opening sentence. On a reel that's only half of it, because the picture arrives before the words do. Someone scrolling sees your first frame before they've heard a syllable, and you can't count on the sound being on.

• The first frame has to stop the thumb. It should show something happening: the finished result, the mess before it, hands mid-task, a face looking down the lens. A logo or an empty room shows nothing.
• The first line has to keep them. Spoken and on screen as text, it tells the viewer who this is for and what they get if they stay.

The two should agree. If the frame shows a cracked phone screen, the line shouldn't open on your opening hours. When I script a reel I write the first frame as a shot description above the first line, so whoever films it knows the picture is part of the hook too. Getting that shot right is a filming job as much as a writing one, and my guide on how to film professional-looking video on your phone covers the light, sound and framing side.

how to write a hook for a reel in five steps

1. start from one viewer and one problem

Before writing a word, finish this sentence: "This reel is for someone who…" A bakery's reel isn't for "foodies". It's for someone ordering a birthday cake for Saturday who's worried it won't look like the photo. The narrower the person, the easier the hook, because you can name their problem in their own words.

2. write five versions, not one

The first hook you write is the one you already had in your head, and it's usually the most generic. I write at least five and pick from the last three. Change the angle each time: a question, a mistake, a result, a "you" statement, a number.

3. make it concrete, not mysterious

"You won't believe this trick" feels like a hook and mostly isn't. A registered report in Scientific Reports by Marianne Aubin Le Quéré and J. Nathan Matias analysed 8,977 headline experiments. When headlines were too vague, making them more concrete increased clicks. When they were already very concrete, adding more detail decreased them. The authors' conclusion: headlines that give just the right amount of information do best.

For a reel, that means opening the gap with real nouns. "The $12 fix that stopped our pastry cracking" opens a question and tells the viewer exactly what world they're in. "This changed everything" doesn't.

4. lean on the problem, then actually solve it

Problems pull harder than promises. In a study in Nature Human Behaviour, Claire Robertson and colleagues analysed 22,743 randomised experiments on Upworthy headlines and found that, for a headline of average length, each additional negative word increased the click-through rate by 2.3%.

That's headlines, not reels, so treat it as a direction. In my experience, a line like "Three mistakes that make your bathroom look smaller" holds more people than "Three tips for a bigger-looking bathroom". The catch is that the reel has to pay off what the hook started. A hook that promises a mistake and then delivers a sales pitch teaches people to skip you next time.

5. run the mute test

Watch your first three seconds with the sound off. Can you tell who it's for and what's coming? If not, put the first line on screen as text, large, in the top half of the frame and clear of the captions and buttons along the bottom. The text and the spoken line can differ slightly, but they should make the same promise.

the first frame: what to show before anyone speaks

Open on the most interesting moment. If the reel ends with a finished kitchen, consider opening on two seconds of the finished kitchen, then cutting back to the start. Showing the payoff first gives the viewer a reason to find out how you got there.

TikTok's own ad guidance points the same way. Its creative tips for auction ads say over 63% of the videos with the highest click-through rate highlight their key message or product within the first 3 seconds. That research is about paid ads, but the logic carries to organic reels: say the important thing early.

First frames that work, in my experience:

• The result: the finished cake, the clean drain, the shelf after it's styled.
• The problem: the cracked tile, the tangled cables, the empty booking calendar.
• Hands mid-task: pouring, cutting, wiring. Movement in frame reads as "something is happening".
• A face mid-sentence: start the clip once you're already talking.

What to cut: logo intros, "hi guys, welcome back", and any shot of you walking into frame. Those can live later in the reel, or nowhere.

reel hook examples: before and after

These are my own rewrites to show the method. The business types are typical of who I work with; the lines are illustrative, not quotes from clients.

• Plumber. Before: "Today we're talking about blocked drains." After: "This is what was blocking a kitchen sink in Leeds last week." First frame: the gloved hand holding it up.
• Skincare brand. Before: "Introducing our new night serum!" After: "If your skin feels tight every morning in winter, this is probably why." First frame: a close-up of dry skin under side light.
• Café. Before: "Come try our new menu." After: "We sell out of this by 10am every Saturday." First frame: the last one on the tray.
• Accountant. Before: "Five tax tips for sole traders." After: "The receipt most sole traders throw away that they could have claimed." First frame: a hand screwing up a receipt.

Every "after" names a specific person or problem, opens a concrete gap, and has a first frame that shows something before a word is spoken.

Where p.a. fits: I write the hooks, scripts and first-frame notes for the reels I edit, so the person filming knows exactly what the opening shot needs to be. You can see the finished work on the homepage.

hooks that backfire

• Bait with no payoff. "Wait for the end" with nothing at the end. It may lift one reel and cost you every one after it.
• Vague curiosity. "This trick" and "the secret" with no noun attached. The headline study above is why.
• The slow start. Context first, point second. Flip it.
• A hook for the wrong person. A clever line that pulls in viewers who'll never buy from you. Views from strangers who don't fit aren't worth much to a local business.

how to tell if your hook is working

Open the insights on a reel and look at its skip rate and retention chart. A sharp drop in the first few seconds means the hook lost people; a slow slide later means the middle did. Compare your reels against each other. Your audience and niche set your baseline, so a number from someone else's account tells you little.

If you want a cleaner test, keep the body of a reel the same and change only the opening, then post the second version a few weeks later. One test proves little, but a pattern across several reels tells you which hook styles your audience responds to. Posting often enough to see a pattern matters too; I wrote separately about how often a small business should post.

first frame, first line, then keep the promise

How to write a hook for a reel comes down to one idea: the first frame stops a stranger, the first line tells them why to stay, and the rest of the reel keeps the promise. Write five, make them concrete, check them on mute, and judge them by skip rate. How clever they sounded when you wrote them doesn't count.
