Synthesizable in Remotion · key components of the shofo-ai-launch-template template.

VerticalPhoneScreenMontage

Rapidly cuts between various short-form vertical videos, simulating a social media feed. Each video is contained within a rounded-rectangle phone screen mask.

+ Code construction recipe

Use a sequence of <Video> components, each wrapped in a <AbsoluteFill> with a `borderRadius` and `overflow: hidden` style. Animate `opacity` and `scale` for quick transitions, potentially using `spring` for a subtle bounce on entry/exit.

DataOverlayFounder

The founder is speaking on screen, while abstract data visualizations, floating particles, and subtle grid lines are composited over and around him.

+ Code construction recipe

Layer a <Video> component for the founder with <Canvas> or <SVG> components for the data graphics. Use `interpolate` for particle movement and `opacity` changes. Apply `blend-mode` CSS properties for seamless integration of graphics with the live-action footage.

AbstractLightTrailReveal

Dynamic, glowing purple light trails swirl and animate across a dark background, often used as a backdrop for text or a logo reveal.

+ Code construction recipe

Implement using a <Canvas> component with WebGL shaders or a series of SVG paths animated with `stroke-dasharray` and `stroke-dashoffset` properties. Animate `transform` and `opacity` of multiple overlapping shapes to create the swirling effect, potentially using `noise` functions for organic movement.
