youtube-intro-outro

youtube-intro-outro is a skill for Claude Code from iart-ai/youtube-video-skills. It costs 122 tokens per session (3,001 once invoked), scanned A, a copy of youtube-intro-outro, MIT.

A skill for making reusable YouTube intro and outro animations. An intro is the short opening identity clip; an outro is the closing layout that can include subscribe and next-video elements.

In plain words
What is it for?
Use it to create logo stings, channel bumpers, end cards, reusable brand templates, and logo reveals timed to audio.
Why use it?
It gives recurring channel videos a consistent opening and closing while accounting for where YouTube places clickable end-screen elements.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

youtube-intro-outro scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

YouTube Intro & Outro

Build the two pieces of motion that bracket every video on a channel: a 3-5s branded intro (logo sting that says "this is my channel") and an outro whose last ~20s host YouTube's clickable end-screen elements (subscribe + next video). Both must respect hard platform constraints — intro length affects retention; outro layout must dodge YouTube's overlaid UI — and both should be one reusable template where only the brand changes.

When to use

  • Channel intro / bumper / logo sting (a 3-5s identity hit before content).
  • Outro / end screen / end card (the last ~20s with subscribe + next-video cards).
  • A reusable brand template: swap name, logo, colors, sting, and re-export.

Two hard rules (platform, not taste)

  1. Keep the intro 3-5s, the logo hit 1-2s. Anything longer than 5s causes measurable viewer drop-off, which hurts the video in the algorithm. The intro confirms the channel and gets out of the way.
  2. The outro must be ≥20s of held, quiet layout, and the video ≥25s total. YouTube only allows end-screen elements in the final 5-20s, and the video must be at least 25 seconds long. Design the outro plate around where those elements land — never put your own content under them.

Intro: the logo sting

A sting is three beats in ~3.5s: a windup (motion building tension), an impact (logo snaps to full on the audio hit), and a settle (micro-overshoot relaxing to rest). The brand mark must land exactly on the sound's impact frame, not near it.

Beat Window Job
Windup 0-0.8s whoosh / build; logo not yet readable
Impact ~0.8s logo snaps to full on the audio hit + a white flash
Settle 0.8-1.2s overshoot relaxes to rest; tagline fades in
Hold 1.2-3.5s brand legible, then cut to content
import {useCurrentFrame, useVideoConfig, spring, interpolate, Img, Audio, staticFile} from "remotion";

export const LogoSting = ({brand}) => {
  const frame = useCurrentFrame();
  const {fps} = useVideoConfig();
  const IMPACT = Math.round(0.8 * fps);            // logo lands here, on the sting hit

  // overshoot scale: springs up past 1, settles to 1 (the "snap")
  const scale = spring({frame: frame - IMPACT, fps, config: {damping: 9, mass: 0.5}, from: 1.18, to: 1});
  const logoOpacity = frame < IMPACT ? 0 : 1;
  const flash = interpolate(frame - IMPACT, [0, 6], [0.9, 0], {extrapolateLeft: "clamp", extrapolateRight: "clamp"});

  return (
    <div style={{flex: 1, background: brand.bg, display: "flex", alignItems: "center", justifyContent: "center"}}>
      <Audio src={staticFile(brand.sting)} />        {/* impact of this file must sit at 0.8s */}
      <Img src={staticFile(brand.logo)} style={{width: 420, opacity: logoOpacity, transform: `scale(${scale})`}} />
      <div style={{position: "absolute", inset: 0, background: "#fff", opacity: flash}} />
    </div>
  );
};

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
