Codepawl’s 0:31 launch film runs 19 scenes, about 1.6 s each. The product is on screen from the first frame and 5 features are revealed. The call to action lands at 0:23 (76% in), over a voiceover. The video opens with a line-drawn cube logo, runs a tilted two-card demo of an agent prompt compiling into a render, then cuts through a fast montage of 3D scenes each tagged by a wipe-in code callout, and closes on a locked logo card with a GitHub URL. Its signature moves are the hard cuts between full-bleed renders on black, the leader-line code labels, and the recurring isometric cube mark.

An Xuan - Introducing 67js A 3D engine that any AI agent can drive, through 23, scene by scene

· 19 scenes as text

  1. 01 · Product intro · 0:00–0:03

    A thin white line draws an isometric cube at the center of a black screen. The cube shifts left as the wordmark 67js scales in to its right, and the tagline 3D engine that AI agents drive fades in below.

    On-screen text: “67js”, “3D engine that AI agents drive”

    Techniques: Kinetic type

    Camera: Static

  2. 02 · Demo · 0:03–0:12

    Two tilted 3D UI cards sit on black. The left card types a prompt, then a list of agent steps fills with checkmarks; the right card runs a progress bar that completes into a mountain-lake render, then the preview card slides forward to center.

    Techniques: 3D mockup, UI zoom

    Camera: Push in

  3. 03 · Demo · 0:12–0:13

    A 3D lakeside landscape, snow-capped peaks over a still reflective lake, opens inside a preview window. The window frame retracts and the view widens as the camera eases back. A white credit caption holds at the lower left.

  5. 05 · Feature reveal · 0:13–0:16

    A blurred book illustration fills the background while a white counter climbs from 20 to 23 beside the title MCP tools. Dark monospace tool tags fade in row by row below, matching the count.

  6. 06 · Feature reveal · 0:16–0:17

    A blurred dark 3D backdrop sits behind a bold white heading and a smaller subtitle line. Below, rows of rounded pill tags list tool names, mostly dark with white text and a few white with black text. The composition holds static.

    A low-poly 3D lakeside scene with snow-capped mountains and a reflective lake fills the frame. A dark rounded card fades in at left with a bold title and a monospace code line, and a thin leader line with a dot points down to the water surface.

    A 3D lakeside render shows snow-capped mountains mirrored in a calm lake; a dark rounded callout on the left reads Water reflection with a code line, a yellow leader line pointing to the water. The shot cuts to a 3D stone cathedral interior with tall stained-glass windows.
