SlideIn

A direction-parameterized translate-and-fade entrance. Text slides into place from 'up', 'down', 'left', or 'right' on SPRING_SMOOTH while opacity fades from 0 to 1 — all settling without overshoot. Travel is a calm 16px by default: the eye feels the motion, it isn't dragged by it.

Props

Name	Type	Default	Notes
`text`	`string`	`"Onda"`	What to slide in.
`delay`	`integer ≥ 0`	`0`	Frames before the animation starts.
`duration`	`integer ≥ 1`	`DURATION.base` (18)	Target frames to fully settle.
`direction`	`"up" \| "down" \| "left" \| "right"`	`"up"`	Direction the text moves toward as it settles. `"up"` starts below and rises.
`distance`	`number`	`16`	Pixels of travel. Keep within 12–24 — Onda travel is deliberately small.
`color`	`string`	`"#F2F2F4"`	Text color — defaults to `--onda-text`.
`fontSize`	`number`	`96`	Pixels.
`fontFamily`	`string`	`'"Clash Display", sans-serif'`	The Onda display font. Never default to Inter / Arial / system.
`fontWeight`	`number`	`600`	Font weight.
`letterSpacing`	`string`	`"normal"`	CSS letter-spacing (e.g. `"-0.02em"`, `"0.06em"`).
`lineHeight`	`number`	`1.1`	Unitless line height.
`align`	`"left" \| "center" \| "right"`	`"left"`	Text alignment.
`placement`	`Placement?`	–	Where on the canvas this sits. Region (`"center"`, `"upper-third"`, …) or `{ x, y, anchor }` in 0..1 canvas fractions. Coordinates may be negative or >1 for off-canvas.

Usage

TSX

import { Composition } from 'remotion';
import { SlideIn, slideInSchema } from './components/onda/slide-in/SlideIn';

export const Root: React.FC = () => (
  <Composition
    id="MySlide"
    component={SlideIn}
    durationInFrames={60}
    fps={30}
    width={1080}
    height={1920}
    schema={slideInSchema}
    defaultProps={{
      text: 'Hello',
      delay: 0,
      duration: 18,
      direction: 'up',
      distance: 16,
      color: '#F2F2F4',
      fontSize: 96,
      fontFamily: '"Clash Display", sans-serif',
    }}
  />
);

Motion notes

Uses entrySlide from lib/choreography.ts — direction-parameterized translate + fade on SPRING_SMOOTH. No overshoot. Don't reduce damping for a "pop."
Duration defaults to DURATION.base (18 frames ≈ 0.6s at 30fps).
Travel defaults to 16px (SPACING[1]) — keep distance within the 12–24 band. Larger jumps break the signature.
direction names the settling direction: 'up' rises into place from below, 'down' falls in from above, 'left' slides leftward from the right, 'right' slides rightward from the left.
All interpolate calls clamp at both ends — the component is correct on frame 0 and on any frame past delay + duration.
