Community Post as Proof — effect skill for quotes & reviews

For AI agents: find the right skill in one call — curl -s "https://skills.varg.ai/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://skills.varg.ai/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.

A real community post or comment card pops over the footage with its upvotes counting up.

What it does

Built on Reddit Post Card by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's.

Reddit-style or YouTube-comment-style card, platform-faithful; the text types on, then the vote count rises.

When: Developer and consumer products where community chatter is more believable than a logo.

Watch out: Do not fake platform UI for posts that never existed; quote real ones and blur usernames if needed.

Timing: Card pop 0.3 s, typing 30–40 ms/char, count-up 0.8 s.

Also called: reddit post, forum thread proof, comment card

In HyperFrames

npx hyperframes add reddit-post

Or npx hyperframes add yt-comment-card for comment-style proof over footage.

In Remotion

const chars = Math.floor(interpolate(frame,[6,6+text.length*1.1],[0,text.length],{extrapolateLeft:'clamp',extrapolateRight:'clamp'}));
<p>{text.slice(0,chars)}</p>

In CapCut

Add the screenshot as Overlay, Animation In "Pop up"; place it in the upper third so captions stay clear.
