By name: remotion-3d-ticker description: Creates infinite 3D vertical scrolling ticker animations in Remotion. Use when you need to build a parallax gallery, infinite image scroll, multi-column continuous vertical scrolling effect, or a 3D photo wall (3D照片滚动墙 / 3D相册瀑布流).
Remotion 3D Vertical Ticker
This skill provides a reusable architectural pattern and component for creating infinite, multi-column 3D scrolling animations (often used for photo galleries, 3D照片滚动墙, tech-stack showcases, or credit rolls) in Remotion.
How it works
The infinite scrolling illusion is achieved using domain duplication and modular arithmetic, combined with CSS 3D transforms:
- The Math of Infinity: We duplicate the content list (
[...items, ...items]). We calculate a `progress` from 0 to 1 based on the frame rate and desired loop duration. We translate the column from `0%` to `-50%` (or `-50%` to `0%` for reverse). Because the content is duplicated, the frame at `-50%` looks identical to the frame at `0%`, creating a seamless loop when it resets. - 3D Perspective: A parent wrapper applies `perspective: 1000px`, `rotateX(20deg)`, and `scale(1.2)`. The scale is crucial to ensure the tilted top and bottom edges stretch beyond the 2D screen bounds, preventing empty background bleeding.
- Masking: CSS `linear-gradient` overlays are placed absolutely at the top and bottom with a high `zIndex` to smoothly fade the content into the background color.
How to use this skill
When a user requests a vertical scrolling gallery or infinite ticker:
- Copy the asset: Provide or copy the generic component located at
assets/VerticalTicker.tsxinto their project's components/animations folder. - Configure: Guide the user to import and render the
<VerticalTicker />component within their Remotion<Composition />. - Adapt Data: The component is data-agnostic. It accepts any array of image URLs or React nodes as columns. You can specify different `durationInSeconds` and `direction` (1 or -1) per column to achieve parallax.
