Use Mapbox GL JS for rendering maps in Remotion when the user wants Mapbox styles or higher-fidelity map visuals and has a Mapbox access token. Use Turf for geospatial operations such as great-circle routes, distances, slicing lines, and positions along routes.
Use this technique only when the user has a Mapbox access token and wants Mapbox styles or data.

Install Mapbox GL JS and Turf with the project's package manager.
npm i mapbox-gl @turf/turf
bun i mapbox-gl @turf/turf
yarn add mapbox-gl @turf/turf
pnpm i mapbox-gl @turf/turf
Import the Mapbox CSS once in the component or an app-level stylesheet:
import 'mapbox-gl/dist/mapbox-gl.css';
Mapbox requires a public access token. Prefer passing it as an input prop or reading it from an environment variable that is available to the bundled Remotion code.

if (!mapboxAccessToken) {
throw new Error('Set REMOTION_MAPBOX_TOKEN to render Mapbox maps.');

Animated examples should keep the loaded map in React state and skip per-frame updates until that state is set.
This example shows the recommended pattern for route animations:
jumpTo() with animated center, zoom, bearing, and pitch.continueRender().import * as turf from '@turf/turf';

For a validated live-camera route animation, animate center, zoom, bearing, and pitch with jumpTo():
map.jumpTo({
center,
zoom,
bearing,
pitch,
});
Keep route progress and camera progress separate if the camera needs to lead, lag, zoom out, or zoom back in. For cinematic 3D camera moves, load the 3D flyover branch from the parent skill.
Use GeoJSON sources for lines. Unless the user asks, do not add glow effects or extra decorative points.
For geodesic flight routes, use Turf:
const line = greatCircleLine(start, end);
const distance = turf.length(line);
const partialLine = turf.lineSliceAlong(
line,
0,
// Keep the route non-empty at progress 0.
Math.max(0.001, distance * progress),
);
For a visually straight line on the map, use a simple GeoJSON LineString between the two points instead of greatCircle().
Use map-native GeoJSON layers for markers and labels:
mapInstance.addSource('markers', {
type: 'geojson',
data: turf.featureCollection([
turf.point([-118.2437, 34.0522], {name: 'Los Angeles'}),
]),
});
mapInstance.addLayer({
id: 'marker-dots',
type: 'circle',
source: 'markers',
paint: {
'circle-color': '#f03b20',
'circle-radius': 12,
'circle-stroke-color': '#ffffff',
'circle-stroke-width': 4,
},
});
mapInstance.addLayer({
id: 'marker-labels',
type: 'symbol',
source: 'markers',
layout: {
'text-allow-overlap': true,
'text-anchor': 'top',
'text-field': ['get', 'name'],
'text-offset': [0, 0.9],
'text-size': 28,
},
paint: {
'text-color': '#111111',
'text-halo-color': '#ffffff',
'text-halo-width': 3,
},
});
Make marker sizes and label font sizes large enough for the composition resolution.
Default to Mapbox Standard:
style: 'mapbox://styles/mapbox/standard'
If the user requests another style, use any valid Mapbox style URL.
For WebGL map renders, prefer single concurrency and ANGLE:
bunx remotion render [composition-id] out/video.mp4 --gl=angle --concurrency=1
Use the equivalent package runner for the project. In npm projects, use npx; in Bun projects, use bunx.
