Playwright Video Recording

Playwright can record browser interactions as video - perfect for demo footage in Remotion compositions.

Quick Start

Installation

# In your video project
npm init -y
npm install -D playwright @playwright/test
npx playwright install chromium

Basic Recording Script

// scripts/record-demo.ts
import { chromium } from 'playwright';

async function recordDemo() {
  const browser = await chromium.launch();
  const context = await browser.newContext({
    viewport: { width: 1920, height: 1080 },
    recordVideo: {
      dir: './recordings',
      size: { width: 1920, height: 1080 }
    }
  });

  const page = await context.newPage();

  // Your recording actions
  await page.goto('https://example.com');
  await page.waitForTimeout(2000);
  await page.click('button.demo');
  await page.waitForTimeout(3000);

  // Close to save video
  await context.close();
  await browser.close();

  console.log('Recording saved to ./recordings/');
}

recordDemo();

Run with:

npx ts-node scripts/record-demo.ts
# or
npx tsx scripts/record-demo.ts

Recording Configuration

Viewport Sizes

// Standard 1080p (recommended for Remotion)
viewport: { width: 1920, height: 1080 }

// 720p (smaller files)
viewport: { width: 1280, height: 720 }

// Square (social media)
viewport: { width: 1080, height: 1080 }

// Mobile
viewport: { width: 390, height: 844 } // iPhone 14

Video Quality Settings

const context = await browser.newContext({
  viewport: { width: 1920, height: 1080 },
  recordVideo: {
    dir: './recordings',
    size: { width: 1920, height: 1080 } // Match viewport for crisp output
  },
  // Slow down for visibility
  // Note: slowMo is on browser launch, not context
});

// For slow motion, launch browser with slowMo
const browser = await chromium.launch({
  slowMo: 100 // 100ms delay between actions
});

Recording Patterns

Form Submission Demo

import { chromium } from 'playwright';

async function recordFormDemo() {
  const browser = await chromium.launch({ slowMo: 50 });
  const context = await browser.newContext({
    viewport: { width: 1920, height: 1080 },
    recordVideo: { dir: './recordings', size: { width: 1920, height: 1080 } }
  });
  const page = await context.newPage();

  await page.goto('https://myapp.com/form');
  await page.waitForTimeout(1000);

  // Type with realistic speed
  await page.fill('#name', 'John Smith', { timeout: 5000 });
  await page.waitForTimeout(500);

  await page.fill('#email', '[email protected]');
  await page.waitForTimeout(500);

  // Click submit
  await page.click('button[type="submit"]');

  // Wait for result
  await page.waitForSelector('.success-message');
  await page.waitForTimeout(2000);

  await context.close();
  await browser.close();
}
