An intro is not a title card you play out of habit — it is the three to five seconds that decide whether a viewer stays or scrolls. On most feeds a large share of the audience makes that call in the first few seconds, so a long, self-indulgent opener costs you the very people it was meant to impress. The goal of this workflow is the opposite: a short, branded, hook-led opener that earns the next line and can be reused across a channel.

The method below is tool-agnostic — it works whether you build the intro in a template maker (Renderforest, Canva, CapCut), generate it from a prompt (an AI video tool), or animate it by hand. The steps are the decisions that matter regardless of tool: what the intro is for, how long it runs, what the hook says, and how it exports for the platform. Get those right and the tool is just execution.

The steps

  1. Decide the intro's job and length before you open a tool. An intro does one of a few jobs: a reusable channel sting (logo plus name), a hook opener for a single video, or a course/webinar title card. Pick one — they are not the same clip. Then set the length to the platform: about three to five seconds overall, up to five or six on YouTube with a logo, and three seconds or less for TikTok, Reels, and Shorts.
  2. Gather your brand assets first. Have your logo (transparent PNG), one or two brand colors, a single font, and one short music track ready before you build. An intro reads as "branded" only when those are consistent with the rest of your content. Sorting them up front means you build once instead of restarting when the colors clash.
  3. Write the hook line — this is the actual retention lever. The words on screen (or spoken in the first second) matter more than the animation. Write one line that states the payoff or opens a curiosity gap: what the viewer gets, or a claim they need resolved. "5 edits that doubled my watch time" beats "Welcome to my channel." Cut anything that sounds like throat-clearing.
  4. Build or generate the opener. In a template maker, pick an intro/logo-animation template and swap in your assets. In an AI generator, prompt it with the hook, brand colors, and vibe, then refine with follow-up edits. Keep any logo reveal to one or two seconds maximum — the logo supports the hook, it does not replace it. On short-form, often skip the logo entirely and lead with a bold caption.
  5. Add music and on-screen captions. A short, punchy track sets energy in the first frame; make sure it is licensed or royalty-free. Add captions or a bold text overlay for the hook line, because a large share of feed viewing happens sound-off — an intro that only works with audio fails silently for most of the audience.
  6. Export to the platform's spec and front-load it. Export vertical 1080×1920 for TikTok/Reels/Shorts and 1920×1080 for standard YouTube — do not reuse a 16:9 intro on a 9:16 feed, it will letterbox and look amateur. Then place the intro at the very start of the video, or generate the full video with the hook already front-loaded so there is no separate attach step.
  7. Test the first three seconds muted. Play only the opening three seconds with the sound off and ask: is it obvious what this video is about, and is there a reason to keep watching? If not, tighten the caption, cut the logo time, or open on motion. The muted-first-three-seconds test is the closest thing to how the feed actually shows your intro.

Common gotchas

  • A long intro is the most common mistake — anything over five seconds, or a logo that hogs three of them, trains viewers to skip. Shorter almost always wins.
  • Reusing one 16:9 desktop intro across vertical platforms letterboxes it. Export a native 9:16 version for TikTok, Reels, and Shorts.
  • An intro that only works with sound on fails for the sound-off majority. Put the hook in on-screen text, not just voiceover or music.
  • Generic stock-footage intros read as templated and forgettable. Lead with your logo, your colors, and a specific hook line, not a stock city skyline.
  • A logo reveal is not a hook. On short-form, the brand recognition you want comes from consistency over many videos, not from a three-second animation at the front of each one.
  • Copyrighted music in an intro can get the whole video muted or claimed. Use a licensed or royalty-free track, especially for a sting you will reuse on every upload.
Legal note

Music and stock footage in an intro carry licensing terms. A popular song used without a license can get your video muted, claimed, or taken down under a platform's Content ID, even for a three-second sting — use royalty-free or properly licensed tracks and confirm the license covers commercial and social use. If your intro uses an AI avatar or a cloned voice, get consent before using a real person's likeness, and disclose AI-generated or synthetic elements where the platform requires it (YouTube, TikTok, and Meta all have disclosure rules). This is general guidance, not legal advice.

Where Kompozy fits

Making one intro is a Saturday project. Making a fresh, on-brand opener for every video you post is where the workflow above breaks — nobody re-writes a hook, re-swaps a logo, and re-exports a sting for five posts a week. Kompozy removes the attach step entirely: instead of building an intro and gluing it to footage, it generates the whole video with the hook already front-loaded, on brand, every time. Persona VFX HeyGen prepends a five-second generative VFX hook and, because the engine ranks several candidates against your script, you get the strongest opener rather than the first one. Marketing Shorts open on a four-second HeyGen hook before the demo footage. And because every branded video is driven by your AI Influencer persona pool and Persona Brief, the recurring face, voice, and styling that a channel intro is supposed to establish stay consistent across every upload — without re-editing an opener each time. The same source then fans into carousels, quote cards, blogs, and newsletters across the nine-platform publishing surface, each opening the way that platform rewards. Starter ($99/mo, 5,500 credits) fits a solo creator front-loading hooks on a lighter cadence; Pro ($299/mo, 18,000 credits) covers a full multi-platform week on autopilot behind a per-post review gate; Enterprise is custom for multi-brand teams. Build a one-off sting in a template maker if that is all you need — Kompozy is for when every video needs a strong opener and you are done making them by hand.

Frequently asked questions

How do I make an AI video intro for free?

Use the free tier of a tool like CapCut, Canva, Adobe Express, or InVideo: pick an intro template or prompt one, swap in your logo and colors, add a hook line and a royalty-free track, and export. Free tiers usually add a watermark and cap export quality, so treat free as a trial — most tools remove the watermark on plans starting around $10–20 a month.

How long should an AI video intro be?

Three to five seconds for most videos, and shorter is trending. YouTube can stretch to about five or six seconds with a logo sting; TikTok, Reels, and Shorts want three seconds or less, often with no logo and a bold caption instead. A large share of viewers decide in the first few seconds whether to stay, so a long intro works against you.

Should I put my logo in the intro?

On YouTube, yes — a one-to-two-second logo-and-name sting builds channel recognition you can reuse for years. On short-form (TikTok, Reels, Shorts), usually skip it and lead with a caption hook; brand recognition there comes from consistent style across many videos, not a logo animation that costs you the first three seconds.

What makes an intro actually hold attention?

The hook, not the animation. State the payoff or open a curiosity gap in the first line of on-screen text, keep it under five seconds, put the words on screen for sound-off viewers, and open on motion rather than a static logo. Test it by watching the first three seconds muted — if the value is not obvious, the intro is too slow.

Can AI generate the whole intro, or just edit a template?

Both exist. Template makers (Renderforest, Canva, Placeit) have you customize a pre-built animation with your assets. AI generators build the opener from a text prompt — pulling footage, writing a hook, adding voiceover and captions. A content engine goes further and generates the whole video with the hook already front-loaded, so there is no separate intro to attach.
