The Preview SDK lets you display video and image previews in your web app prior to creating a final MP4, GIF, JPEG or PNG through the API. This is useful when developing a web-based editing or customizer tool, and want to show a real-time rendering in the browser.
This package is for browser-based apps, and it works with any framework such as React, Angular, Vue, as well as plain Javascript. For creating videos and images using Node.js, refer to the creatomate library instead, a different NPM package that can be found here.
Creatomate is a media generation API for editing and rendering videos and images using code. The platform uses templates and JSON for generating MP4, GIF, JPEG or PNG files. All processing is handled by Creatomate's cloud infrastructure, so you do not need to maintain your own servers.
Install the package using the following command:
npm install @creatomate/previewYou can now load a video template (or JSON) as follows:
import { Preview } from '@creatomate/preview';
// The following assumes that you have a HTML element like this: <div id="container"></div>
const containerElement = document.getElementById('container');
// Initialize a preview to be spawned within the container
const preview = new Preview(containerElement, 'player', 'YOUR_VIDEO_PLAYER_TOKEN');
// Once the SDK is ready, load a template from the project
preview.onReady = async () => {
await preview.loadTemplate('YOUR_TEMPLATE_ID');
// You can also load a video from JSON:
// await preview.setSource({ /* Your JSON here */ });
};Check out the demo code provided below for a more comprehensive example.

Because live video rendering is very demanding on the device's hardware, this library only works on modern desktop web browsers, such as Chrome, Firefox, Edge, Opera, and Safari. Mobile devices are not supported. Render an MP4 preview through the API to support smartphone devices. Tip: Use the render_scale API parameter (10% to 100%) to generate a low-resolution preview without changing the composition or template.
