How to Make a Explainer Video for LinkedIn in {{year}}

The spec for LinkedIn

LinkedIn is a sound-off, feed-first environment with a professional scroll pattern. You win by respecting the platform's constraints and designing for clarity. Here are the up-to-date specs that matter in 2026:

Aspect ratios and dimensions

Vertical 9:16 - 1080x1920. Best for mobile reach and full-screen immersion on tap.
Square 1:1 - 1080x1080. Reliable in-feed, strong for carousel-style storytelling.
Horizontal 16:9 - 1920x1080. Works for demos and screen recordings, often shows smaller in-feed.
Safe areas - keep essential text within the center 80 percent width, and 12 percent from top and bottom to avoid UI overlap in the feed header and engagement bar.

Duration and file limits

Organic post duration - 3 seconds to 10 minutes. The sweet spot for explainers is 45 to 90 seconds.
Frame rate - up to 60 fps. 24 to 30 fps is standard for talking-head explainers.
Format - MP4 H.264, AAC audio. Target 8 to 12 Mbps for 1080p to balance quality and upload reliability.
File size - up to 5 GB. Keep under 250 MB for snappy uploads and faster review cycles.

Autoplay, sound, and captions

Autoplay is muted by default in-feed. Design for zero audio.
Always-on burned-in captions or attach an SRT. Burned-in captions increase retention on mobile.
Design an arresting first frame that reads without sound. Treat it like a billboard.

Cover image and first frame

Upload a clean thumbnail with a 5 to 7 word headline and a small brand mark.
Avoid dense text or busy backgrounds. High contrast, no edge-to-edge body copy.

The structure that works

Your explainer should feel brisk and outcome focused. Below is a beat map you can follow based on thousands of high-performing LinkedIn explainers.

60 to 75 second core structure

0 to 3s - Visual hook. Motion headline or prop that tees up the problem. No logo stings at the top.
3 to 8s - Problem in plain language. One sentence the audience immediately recognizes.
8 to 20s - Promise and preview. What you will show and why it is different. List 3 bullets on screen.
20 to 45s - Steps or framework. Three concise beats with on-screen labels. Each beat gets its own visual reset.
45 to 60s - Mini demo or example. A quick before-after, a screen recording, or a short diagram.
60 to 75s - Payoff and CTA. Summarize the outcome, then a single action like "Comment 'GUIDE' for the checklist" or "DM 'DEMO' for the repo".

30 second sprint version

0 to 2s - Hook visual
2 to 6s - Problem
6 to 16s - Two-step solution
16 to 26s - Example
26 to 30s - CTA

90 to 120 second deep dive

0 to 4s - Hook
4 to 12s - Problem and stakes with one metric
12 to 28s - Framework overview
28 to 85s - Walkthrough with 3 to 4 chapters, each with its own lower third
85 to 100s - Objection handling or quick FAQ
100 to 120s - Recap and CTA

Treat each section like a slide. Every 3 to 5 seconds, add a motion reset or a new visual to refresh attention. On LinkedIn, the first 10 seconds drive stop rate, and clean structure drives completion rate.

Hooks that earn attention

Strong hooks are specific, visual, and outcome oriented. Use one of these formulas, then back it up fast:

Myth to method - "You do not need a landing page to validate demand. Here is a 60 second workflow that gets you signal by lunch."
Before-after bridge - "Yesterday a 14 step handoff. Today 3 clicks. The connector that killed our manual QA."
Numbered teardown - "3 metrics that expose wasted cloud spend, and the 1 query we run every Friday."
Counterintuitive rule - "Shipping slower raised our release quality. The 2 constraints we removed to speed up safely."
Micro demo promise - "Watch me compress a 5 minute onboarding into 40 seconds. No code, just one Zap and a webhook."

Avoid questions that could be answered with "no" in the first second. Lead with a claim you can demonstrate quickly.

Brand + voice that compounds

One great video is fine. A consistent brand system is compounding. A brand kit locks the experience so each post reinforces memory - typography, color, lower thirds, intro and outro patterns, transition speeds, and caption styling. It also reduces decision fatigue for creators and reviewers, which speeds publishing cadence.

Use a per-project brand kit that includes:

Color tokens with accessible contrast pairs for text on video
Heading and caption fonts with weights mapped to on-screen hierarchy
Lower thirds and chapter cards with left-safe and bottom-safe padding
Logo lockups that never occupy the first 2 seconds
Motion rules - 200 to 300 ms ease-in-out on transitions, 8 to 12 px move on kinetic typography
Audio identity for sound-on replays that never competes with narration

Tools like HyperVids let you define a per-project brand kit that is applied automatically to every cut, including fonts, colors, lower thirds, bumpers, and caption styling. It keeps your explainer series consistent across square and vertical outputs so viewers recognize your voice in the first second.

Captions + accessibility

Since sound is off by default, captions are not optional on LinkedIn. Set them up for legibility on small screens and fast scrolls.

Always-on strategy - Burn in captions for mobile clarity, and also attach an SRT for accessibility and search.
Characters per line - 32 to 40 characters, max 2 lines. Break on phrase boundaries, not mid word.
Reading speed - Aim for 140 to 180 words per minute. If the line is long, shorten narration.
Contrast - Maintain a 4.5:1 ratio minimum. Use a semi-opaque background box or stroke on text. White text on a 60 to 80 percent black box is reliable.
Placement - Keep captions at least 12 percent above the bottom edge to clear the like/comment/share bar. Do not exceed the 80 percent width safe area.
Styling - Medium weight sans serif at 46 to 56 px for 1080p. Highlight 1 to 2 keywords per line with color from your brand kit.
Speaker labels - If more than one person, prefix with initials for the first 2 to 3 lines, then drop once established.
File hygiene - Name your SRT as video-filename.en.srt. Check timecodes for 1 to 2 second minimum durations.

A sample HyperVids prompt

Assume your brand kit is already selected in the project. Here is a realistic single-line prompt for a LinkedIn explainer:

"Create a 60 second LinkedIn explainer in 9:16 and 1:1 on '3 steps to cut onboarding churn by 30 percent' with a cold open hook, on-screen bullets, kinetic captions, quick screen recording overlays, and a final CTA to comment 'CHECKLIST' for a PDF."

In HyperVids, powered by the /hyperframes skill and your existing Claude CLI subscription, that prompt yields a talking-head cut with branded lower thirds, motion captions styled to your kit, B-roll from your library, square and vertical renders, a clean thumbnail, and an SRT. You can swap the hook, tighten beats, or re-render alternates in minutes.

Common failure modes

Logo intro eats the hook - Viewers bail before you start. Fix by opening cold and deferring your mark to 0:03 or later.
Wall of text captions - Too many characters per line. Fix by splitting lines, compressing phrasing, and using a background box.
Reading a blog on camera - Monotone narration with dense sentences. Fix by writing for speech with short clauses and verbs up front.
Slow first 5 seconds - No visual change, no claim, no motion. Fix by adding a headline wipe, prop, or cut-in demo.
Jargon without payoff - Fancy terms without a result. Fix by naming a measurable outcome in the first 10 seconds.
Wrong aspect ratio - Horizontal only in a mobile feed. Fix by exporting 9:16 and 1:1, then uploading the better performer natively.
UI collisions - Lower thirds or captions overlap LinkedIn's buttons. Fix by respecting bottom and top safe areas.
No visual resets - Long static shot fatigues viewers. Fix by cutting every 3 to 5 seconds or animating captions.
Buried CTA - Asking once in the last second. Fix by hinting at the CTA at 0:08, then repeating cleanly at the end.
Inconsistent brand - Fonts and colors shift across posts. Fix by using a locked brand kit so the series feels intentional.
Poor audio hygiene - Room echo, uneven levels. Fix by recording in a treated space, using a lav or dynamic mic, and leveling to -14 LUFS integrated.

Conclusion

LinkedIn rewards clarity, brevity, and outcomes. Build for sound-off, lead with a credible claim, present a tight 3 step solution, and make captions beautiful. Use a consistent brand kit so your series compounds, not just a single post. Tools like HyperVids can compress your production cycle from hours to minutes while keeping structure and styling consistent across square and vertical renders. Ship weekly, iterate on the first 10 seconds, and measure comments per view to gauge clarity.

FAQ

What is the optimal length for a LinkedIn explainer?

60 to 75 seconds balances depth and retention. If your story truly needs more, target 90 seconds and add chapter cards. Keep the first 10 seconds punchy in either case.

Should I burn in captions or upload an SRT?

Do both. Burned-in captions maximize comprehension on sound-off autoplay. An SRT supports accessibility, search, and republishing. Ensure styling and timing match so they do not distract.

Square or vertical for LinkedIn?

Vertical 9:16 tends to win on mobile attention, especially for explainers with motion captions. Square 1:1 is a safe second and can perform better for carousels or when your visuals include side-by-side comparisons. Publish the best performer natively, not as an external link.
