End cards & CTAs effects for AI video

For AI agents: find the right skill in one call — curl -s "https://varg.ai/how-to/api/search?q=<what the person wants>" returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://varg.ai/how-to/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the how-to page.

9 effects for end cards & CTAs: how a video ends: the call to action, URL and QR code, subscribe prompt, logo outro and the last line.

Effects (9)

• Logo Lockup Outro — HeyGen: The mark assembles, the wordmark settles beside it, then tagline and URL fade in under it.
• Action Line + CTA Button — HeyGen: One short action line lands, then a real-looking button pops in under it with a soft glow.
• URL Typed Into the Address Bar — Magic UI: A browser bar appears and the product URL types itself in, then the page loads into the hero.
• YouTube End Screen Layout — HeyGen: A 5–20 s outro with clean empty slots for YouTube's clickable video and subscribe elements.
• Scan-to-Try QR Card — HeyGen: A high-contrast QR code with a one-line reason to scan, held long enough to grab a phone.
• Store Badges Close — HeyGen: A short headline settles above equal-size App Store and Google Play badges, often beside a phone.
• Pull Back to the Whole Canvas — HeyGen: The camera pulls out from the last detail to the whole product workspace, then lands on the logo.
• Follow Card Sign-Off — HeyGen: A profile card with avatar, handle and a Follow button that a cursor or tap presses.
• Last Frame Equals First Frame — HeyGen: The ending morphs back into the opening frame so autoplaying feeds loop without a visible seam.

Other kinds of skills

• Prompts: The words a video model obeys: camera angles, shot sizes, lighting, characters, hooks and prompt guides for Seedance, Kling, Veo, FLUX and Higgsfield. Your agent writes the prompt with them, or you paste them into the model.
• Styles: The look of the whole video: art styles, film looks, color grades and LUTs, caption fonts and style references. Pick a style and every shot your agent makes follows it.
• Guides: Know-how your agent reads before it works: how to write a script, storyboard, edit and caption, and how to use Remotion, HyperFrames, GSAP, Three.js and FFmpeg.
• Workflows: A brief in, a finished video out: UGC ads, product videos, music videos, talking heads, explainers, Shorts and short dramas, step by step, with the models and the edit chosen for you.
• Models & tools: Run one model or tool from your agent: Seedance, Veo, Kling, FLUX, GPT Image, Nano Banana, ElevenLabs and 1,200+ more, plus scrapers, trend search and video analysis.
