React is a JavaScript library for building user interfaces with declarative, component-based, and cross-platform design.
It showcases a novel technique for seamless scroll-based video navigation using frame-exact transitions, and provides an open-source engine and skill for others to replicate.
A scroll‑scrubbed "fly through the world" landing page. As you scroll, a pre‑rendered camera glides forward through a miniature clay burger world — market → grill → counter → the burger — as one continuous shot, no cuts. Every frame was generated with Kubeez.

Scroll doesn't move a page here — it drives a camera. Each scene is a short pre‑rendered
video; the engine maps your scroll position to the video's currentTime, so scrolling scrubs
the camera forward through the world. Between scenes, dedicated transition clips glide the
camera from one place to the next, so the whole journey reads as a single continuous flight.

The entire thing — stills, motion, everything — was generated on the Kubeez platform. No external tools. Here's the pipeline:
gpt-image-2, text‑to‑image) sets the palette, angle and light.image-to-video: the camera
begins high and wide, then glides forward and descends into the scene.This is the technique that matters. For each pair of consecutive dives:
transition.firstFrame = the ACTUAL last frame of dive N (extracted from the rendered mp4)
transition.lastFrame = the ACTUAL first frame of dive N+1 (extracted from the rendered mp4)
Feed those two real frames to Seedance 2 as keyframes with a gentle forward‑glide prompt, and it fills the in‑between. Because the transition starts on dive N's real last frame and ends on dive N+1's real first frame
