The first second: openings that stop the scroll

An opening stops the scroll when its first frame already says something: a clear line in a few words, a subject that fills the frame and already moves, and the brand present but small. Do not warm up with a logo or a slow fade. People give a feed post less than two seconds, so the point has to be on screen at frame one.

Why the first second decides the whole video

A feed is not a cinema. Nobody has sat down to watch your film; they are moving their thumb. Figures from Facebook's insights team, quoted by Adweek, say that Facebook users spend an average of 1.7 seconds with a piece of mobile content, against 2.5 seconds on desktop. That is the window your opening has to work in, and it is shorter than most logo animations.

The platforms say the same thing in their own words. TikTok's creative best practices for performance ads tell advertisers to introduce the content proposition in the first 3 seconds and to put the hook in the first 6 seconds. Its Creative Codes guide goes further: it says 90% of ad recall impact and 80% of the awareness impact are captured within 6 seconds. Google's ABCDs of effective video ads open with the same idea under "Attention": get to the heart of the story faster, with engaging pacing and tight framing.

This matters to anyone who makes marketing video, not only to people who buy ads. A launch film on a landing page, an explainer in a LinkedIn post and a product demo on YouTube all start the same way: on a screen next to other things that want attention. The first second decides whether the rest of the film gets a chance.

A teardown of two openings, frame by frame

The clip below shows the same made-up app opened two ways. It has no sound on purpose: judge each opening as a muted viewer in a feed would.

Opening A, logo first. At frame one the screen is almost empty: a dark ground and a brand name at a fraction of its final brightness. At half a second the name is still faint. At one second it is readable, but it says nothing about the viewer. At 1.7 seconds, the average time a mobile viewer gives a post, the frame has still not said what the product does. In the clip, the feed pushes it away at that point.

Opening B, the point first. At frame one the line "Your inbox, sorted for you" is already there, in type large enough to read on a phone, on a colour that stands out from the feed. A big tick sits beside it, and the whole frame settles with a short brake, so something moves from the first frame. Nothing in the frame needs the sound. By half a second the viewer knows who it is for and what they get. The brand, here the made-up name Brightnest, can sit small in a corner from the start.

The difference is not polish. Both openings are designed with care. The difference is order: A puts the brand's moment first and the viewer's reason second, and B does the opposite.

What a scroll-stopping first frame holds

Take the first frame of a strong opening apart and you usually find four things. You do not need all four in every film, but each one you drop needs a reason.

1. The brand, small and early

Early branding helps, as long as it does not replace the hook. System1's research director wrote in February 2026 that ads with an early logo, upfront or in a corner, raised Fast Fluency by 39% and overall brand recall by 13%, tripling Fast Fluency against branding on the end frame only. TikTok's Creative Codes put the limit plainly: branding in the first few seconds should be subtle and not compromise the hook. A corner mark or the product's own packaging does both jobs.

2. The point, in a few words

The line names the viewer's problem or wish, or the result they will get, in their own words. It is short enough to read before the thumb moves. TikTok's guidance gives a pace for on-screen text of 5 to 10 words per second, which is a useful ceiling for a first line.

3. The subject, big and already moving

Google's guidance asks for tight framing and engaging pacing. In practice that means the product, a face or the result fills most of the frame, and something is in motion at frame one: a push-in, a hand, a pour, type that lands. A still frame that holds for a second reads as a frozen video.

4. Words that work with the sound off and better with it on

Sound is not the enemy. Meta's developer blog says over 75% of Reels views on Instagram are sound on, and Google's Core ABCDs summary says YouTube is 95% sound-on. Still, the first second has to read for the viewers who are muted, so the line is on screen and the voice says it too. Our post on captions that work on mute covers the type itself.

Opening patterns that stop the scroll

Most good openings are one of a few patterns. Pick the one your material supports best.

• The viewer's problem. A real moment of the problem, with the line in the viewer's words. "Your inbox, sorted for you" is a problem turned into a promise.
• The result first. Show the finished thing, then go back to how. This suits launch films and before-and-after products.
• The product in action. The thing already doing its job at frame one, with its name on screen. The Gradient Cycling Team Kit 27 film opens on three riders already moving behind the words "Team Kit 27" and "pre-orders open", so the product and the offer are both in the first frame.
• A question the viewer answers yes to. The Good Boy Kitchen film opens on a dog's face with "Fresh dog food" and "Who's a good boy?" on one label: the subject, the category and the hook in one frame.
• Suspense or surprise. TikTok's Creative Codes report that ads that use suspense early lead to a 16% increase in watch time, and that surprise can lead to a 1.7x view-through rate. Surprise still needs a clear subject; a riddle with no product loses the viewer.

A worked example: how much time a first line has

Here is the arithmetic for the clip above, using two of the numbers already quoted. The mobile viewer gives a post about 1.7 seconds on average. On-screen text should run at 5 to 10 words per second.

The line "Your inbox, sorted for you" has 5 words. At 10 words per second it takes 5 ÷ 10 = 0.5 seconds to read. At 5 words per second it takes 5 ÷ 5 = 1.0 second.

In Opening B the line is on screen at 0.0 seconds, so a slow reader finishes at 1.0 second. That leaves 1.7 − 1.0 = 0.7 seconds of margin inside the average window.

In Opening A the logo fade takes the first 1.5 seconds before any line appears. The same line then finishes between 1.5 + 0.5 = 2.0 seconds and 1.5 + 1.0 = 2.5 seconds. Both are past 1.7 seconds. On average the viewer has left before the point is read, however good the line is.

The same sum tells you how long a first line can be. If you want a slow reader to finish within 1.7 seconds with the line on screen from frame one, the limit is 1.7 × 5 = 8.5, so about 8 words. A shorter line leaves more margin.

Opening	Line appears	Read by (fast)	Read by (slow)	Inside 1.7 s?
A: logo first	1.5 s	2.0 s	2.5 s	No
B: point first	0.0 s	0.5 s	1.0 s	Yes

How the first six seconds fit together

The first second stops the thumb. The seconds after it have their own jobs, and the platform guidance gives them a rough order.

1. Frame one to about 1 second: a picture worth stopping for, already moving, with the line on screen.
2. By 3 seconds: the offer or the content proposition is clear, in words and picture, as TikTok's best practices ask.
3. By 6 seconds: the hook has landed and the brand is in the film, where TikTok's guide puts most of the recall and awareness effect.

After that the film can explain, show proof and ask for the action. A viewer who stayed six seconds has chosen to watch.

Common mistakes and how to fix them

• A logo sting at the start. Fix: move the logo to a corner of the first frame and save the full logo moment for the end.
• A black or empty first frame. Fix: start on the hero shot, the product in use or the first words of the line. Look at the very first frame on its own, at phone size, before you publish.
• A line that is too long. Fix: count the words and apply the sum above. Cut to the viewer's problem or the result.
• A hook that needs the sound. Fix: put the spoken line on screen as well, large and on a calm part of the picture.
• A riddle with no subject. Fix: keep the surprise, but show the product or the person it is for in the same frame.
• Testing the whole film when only the start is weak. Fix: keep the body and change only the opening. Our playbook for ad variations shows how to set that test up.

A checklist for your first second

• The first frame is a picture, not a black screen or a logo on its own.
• Something moves from frame one.
• The line names the viewer's problem, wish or result in about 8 words or fewer.
• The line is on screen at frame one and readable on a phone.
• The subject fills the frame, framed tight.
• The brand shows early, small, and never as the first word.
• The opening reads with the sound off, and the voice says the same line.
• By 3 seconds a stranger can say what the product is and what it does.

Questions about video openings

How long is the hook of a video?

The part that stops the scroll is the first second or two, because mobile viewers give a post about 1.7 seconds on average. The hook as a whole runs longer: TikTok asks for the proposition in the first 3 seconds and the hook within the first 6.

Should the logo be in the first second?

Yes, small. In System1's research, an early or corner logo raised overall brand recall and tripled Fast Fluency against a logo on the end frame only. Keep it subtle so it does not take the place of the line.

Do I need captions if most people watch with sound on?

Yes, for the opening at least. Many views are sound-on, but the first second still has to read for viewers who are muted. Put the line on screen and let the voice say it too.

Does the first second matter for explainers and launch films, not only ads?

Yes. Any film that plays in a feed, on a page next to other content or as an autoplay preview is judged in its first frames. The same rules apply: the point first, the subject big, the brand small and early.

Your next film can open on its point. Paste a link to your product or write one line about it in FoxyLab's studio: it writes, voices and animates the film, puts the point in the first frame and renders it in every size, and you change the opening with a note until it stops the scroll.
