What it does
Built on Signup Flow by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's.
Clean card with labeled inputs; each field focuses with a ring, types at human cadence, gets a check; button goes loading → success.
When: Show how fast sign-up or setup is ("30 seconds to your first project").
Watch out: Do not type real-speed long emails; keep values short and speed typing up 2–3×.
Timing: Each field 0.6–1.0 s; button loading 0.4 s; success check 0.4 s.
Also called: signup flow, input typing, onboarding form
In HyperFrames
npx hyperframes add signup-flow
Pair with input-feedback for a shake on a wrong value before the correct one.
In Remotion
// npx shadcn@latest add @remocn/signup-flow
// or compose @remocn/input + @remocn/button with state = f(frame)
In CapCut
Record the real form; speed up typing segments 2–3× (Speed → Normal); add click SFX.

More UI walkthroughs skills
- Zoom to the Action: The full app establishes, then the camera pushes 1.5–2× into the part being used and eases back out.
- 3D Tilted Dashboard Reveal: The dashboard rises from a steep 3D tilt to flat, like a screen lifting toward the viewer.
- Floating UI Panels in Depth: The interface splits into its panels, which float apart in depth with parallax, then snap back.
- UI Builds Itself Piece by Piece: Grey skeleton blocks pulse once, then real cards, charts and text fill in with a stagger.
- Before/After UI Wipe: A divider sweeps across one screen, turning the old version into the new one underneath.
- Card Expands Into Detail: A small card grows into a full detail panel in one continuous shape change.
