Phrase Builds From the Center — effect skill for headlines & callouts

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.

Words arrive one at a time and push the growing phrase so it always sits centered.

What it does

Built on Kinetic Center Build by Remocn (hyperframes), Apache-2.0. The write-up and recipes below are varg's.

First word lands center; each next word drives in from the right and shoves the line left until the full phrase locks center.

When: Say the tagline in sync with the voiceover, word for word.

Watch out: Do not time words to a fixed interval; cue each one from the word timestamps of the voiceover.

Timing: Each word 0.25–0.35 s, expo.out; final hold ≥ 1 s.

Also called: kinetic center build, word push, voiceover words

In HyperFrames

npx hyperframes add kinetic-center-build

Feed word start times from the transcript JSON into the block variables so each push lands on its spoken word.

In Remotion

// npx shadcn@latest add @remocn/kinetic-center-build
const shown = words.filter(w => frame >= w.startMs/1000*fps);

In CapCut

Captions → Auto captions (word-level), then style each caption chunk as a single word in the center; Animation In "Slide left" 0.25 s.
