Sizing and positioning

Use the style prop to control size and position:

<Img
  src={staticFile("photo.png")}
  style={{
    width: 500,
    height: 300,
    position: "absolute",
    top: 100,
    left: 50,
    objectFit: "cover",
  }}
/>

Dynamic image paths

Use template literals for dynamic file references:

import { Img, staticFile, useCurrentFrame } from "remotion";

const frame = useCurrentFrame();

// Image sequence
<Img src={staticFile(`frames/frame${frame}.png`)} />

// Selecting based on props
<Img src={staticFile(`avatars/${props.userId}.png`)} />

// Conditional images
<Img src={staticFile(`icons/${isActive ? "active" : "inactive"}.svg`)} />

This pattern is useful for:

• Image sequences (frame-by-frame animations)
• User-specific avatars or profile images
• Theme-based icons
• State-dependent graphics

Getting image dimensions

Use getImageDimensions() to get the dimensions of an image:

import { getImageDimensions, staticFile } from "remotion";

const { width, height } = await getImageDimensions(staticFile("photo.png"));

This is useful for calculating aspect ratios or sizing compositions:

import {
  getImageDimensions,
  staticFile,
  CalculateMetadataFunction,
} from "remotion";

const calculateMetadata: CalculateMetadataFunction = async () => {
  const { width, height } = await getImageDimensions(staticFile("photo.png"));
  return {
    width,
    height,
  };
};
