Short-form video (think 15–60 seconds) is where attention lives. Audiences swipe fast, so your job is to hook, deliver, and finish with intent. Below is a step-by-step method distilled from leading content and platform guides, with clear specs, shot ideas, editing tools (including CapCut), and platform-specific posting tips.

1) Start with a strong hook (what it is + examples)

A hook is the first 1–3 seconds that stops the scroll. Its only goal: make people think “this applies to me right now.” Popular formats include:

  • Big promise/benefit: “In 30 seconds, you’ll fix shaky phone footage.”
  • Pattern break/visual shock: Start mid-action, use a jump cut, or reveal the “after” first.
  • Contrarian statement: “Stop using this ‘viral’ setting—it’s ruining your videos.”
  • Open loop/question: “Want smoother transitions without buying gear?”
  • Micro-story cold open: Begin at the climax, then rewind.

Why it matters: viewers decide instantly whether to stay. Many top practitioners recommend designing your opener on purpose, not by chance.

2) Shoot smart: framing, light, sound

  • Frame for vertical: Keep eyes around the upper third of frame, with a bit of headroom. Centre key subjects so nothing crucial is cropped by UI overlays (captions, buttons).
  • Light forward: Face a window or use a key light; avoid strong backlight.
  • Sound > pixels: Use a simple clip-on mic or record in a quiet room; poor audio kills retention.
  • Stability: Prop your phone, use a tripod, or brace elbows; add gentle movement (push-in) for energy.

Shot list you can film in minutes:

  • A-roll: Your talking face (primary narrative).
  • B-roll: Hands-on demo, close-ups, product details, before/after, over-the-shoulder, POV, reaction shots, screen recording.
  • Cutaways: Quick inserts that illustrate each tip or claim.
  • Transitions: Whip-pan, match-cut (match motion or shape), snap zoom.

3) Edit quickly (CapCut + alternatives)

CapCut (free, mobile & desktop):

  1. Rough cut: Trim umms and pauses; keep ruthless pace.
  2. Text & captions: Add large, high-contrast captions; emphasise verbs/benefits.
  3. B-roll masking: Layer B-roll over A-roll to illustrate points.
  4. Beat-matched cuts: Use auto-beat detection for snappier rhythms.
  5. Sound polish: Normalise loudness, mild noise reduction.
  6. Export presets: 1080 × 1920, H.264, ~10–20 Mbps.

Other options: Adobe Premiere Rush, VN, InShot (mobile); DaVinci Resolve, Premiere Pro, Final Cut Pro (desktop). Choose the tool you’ll actually use consistently.

4) Export once, publish everywhere (the pixel specs)

Create a master vertical and repurpose. The most compatible vertical format across platforms is:

  • 1080 × 1920 px (9:16) — ideal for TikTok, Instagram Reels and YouTube Shorts.

Notes:

  • Instagram accepts a range of ratios but full-screen Reels present best at 1080 × 1920; keep crucial text within a central “safe zone” to avoid UI overlap.
  • TikTok will also accept 720 × 1280 (9:16) if bandwidth is tight, though 1080 × 1920 looks more professional.

5) Content structure that retains viewers

Use a simple 5-beat template:

  1. Hook (0–3s) – promise, problem, or visual surprise.
  2. Context (3–6s) – who this is for/why it matters.
  3. Value (6–30s) – three snappy tips, each with a visual proof/B-roll.
  4. Recap (2–4s) – ultra-brief summary on screen.
  5. CTA (last 2–3s) – “Comment ‘CHECKLIST’ for the shot list,” “See full demo on YouTube,” or “Follow for daily studio hacks.”

Short-form continues to outperform for engagement and completion—lean into brevity.

6) Platform-by-platform posting tweaks

TikTok

  • Format: 1080 × 1920, 9:16.
  • Caption: Keep the first line hooky; add 3–5 specific hashtags.
  • Style: Fast edits, on-screen text, trends only if relevant.

Instagram Reels

  • Format: 1080 × 1920 (9:16). Keep key text in the central safe area; grid crops can trim edges.
  • Caption: One-line headline + scannable bullets + CTA; pin key words in the first 125 chars.
  • Style: Clean design, branded subtitles; add a cover image that reads at a glance.

YouTube Shorts

  • Format: 1080 × 1920 (9:16).
  • Metadata: Title like a headline; description can carry extra links/context.
  • Style: Tutorials, quick how-tos, and explainers perform strongly; aim for clarity and audio quality.

7) Writing winning post copy (captions that convert)

  • Front-load value: The first sentence must mirror your video hook.
  • Make it skimmable: Short lines, emojis as bullets, 1 clear CTA.
  • One promise, one action: “Save for later,” “Comment ‘GUIDE’,” or “Tap link in bio.”
  • Hashtags: Use a small set of specific tags tied to the content/topic, not generic spam.
  • Cross-posting: Adjust the first line and CTA per platform; don’t paste the same caption everywhere.

8) Quick checklist (copy/paste this into your notes)

  • Hook written before filming.
  • Shoot vertical; eyes on top third; clean light; crisp audio.
  • Film A-roll + at least 5 B-roll inserts.
  • Edit in CapCut; add captions and punchy text.
  • Export 1080 × 1920 (9:16) once; repurpose to TikTok, Reels, Shorts.
  • Caption: bold first line + scannable bullets + single CTA.
  • Post, then review retention and drop-off at 3s/5s to refine hooks.

Follow this workflow and you’ll ship tighter, clearer videos that earn watch time, comments, and clicks—without needing a studio or a full production day.
