Basic Recording Script

基础录制脚本

typescript

// 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:

bash

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');

  });

  document.addEventListener('mousedown', () => cursor.classList.add('clicking'));
  document.addEventListener('mouseup', () => cursor.classList.remove('clicking'));
});

Click Ripple Effect

点击涟漪效果

typescript

// Add click ripple visualization
await page.addStyleTag({
  content: `
    .click-ripple {
      position: fixed;
      width: 40px;
      height: 40px;
      border-radius: 50%;

    @keyframes ripple {
      to {
        transform: translate(-50%, -50%) scale(2);
        opacity: 0;
      }
    }
  `
});

// Custom click function with ripple
async function clickWithRipple(page, selector) {
  const element = await page.locator(selector);
  const box = await element.boundingBox();

  await page.evaluate(({ x, y }) => {
    const ripple = document.createElement('div');
    ripple.className = 'click-ripple';
    ripple.style.left = x + 'px';
    ripple.style.top = y + 'px';
    document.body.appendChild(ripple);
    setTimeout(() => ripple.remove(), 400);
  }, { x: box.x + box.width / 2, y: box.y + box.height / 2 });

  await element.click();
}

typescript

// Add click ripple visualization
await page.addStyleTag({

        transform: translate(-50%, -50%) scale(2);
        opacity: 0;
      }
    }
  `
});

// Custom click function with ripple

  const box = await element.boundingBox();

  await page.evaluate(({ x, y }) => {
    const ripple = document.createElement('div');
    ripple.className = 'click-ripple';
    ripple.style.left = x + 'px';
    ripple.style.top = y + 'px';
    document.body.appendChild(ripple);
    setTimeout(() => ripple.remove(), 400);
  }, { x: box.x + box.width / 2, y: box.y + box.height / 2 });

  await element.click();
}

Output for Remotion

适配Remotion的输出设置

Move Recording to public/demos/

将录制文件移动到public/demos/目录

typescript

import { chromium } from 'playwright';
import * as fs from 'fs';
import * as path from 'path';

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

  // ... recording actions ...

  await context.close();

  // Get the video path
  const video = page.video();
  const videoPath = await video?.path();

  if (videoPath) {
    const destPath = `./public/demos/${outputName}.webm`;
    fs.mkdirSync(path.dirname(destPath), { recursive: true });
    fs.renameSync(videoPath, destPath);
    console.log(`Recording saved to: ${destPath}`);

    // Get duration for config
    // Use ffprobe: ffprobe -v error -show_entries format=duration -of csv=p=0 file.webm
  }

  await browser.close();
}

typescript

import { chromium } from 'playwright';
import * as fs from 'fs';
import * as path from 'path';

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

  // ... recording actions ...

  await context.close();

  // Get the video path
  const video = page.video();
  const videoPath = await video?.path();

  if (videoPath) {
    const destPath = `./public/demos/${outputName}.webm`;
    fs.mkdirSync(path.dirname(destPath), { recursive: true });
    fs.renameSync(videoPath, destPath);
    console.log(`Recording saved to: ${destPath}`);

    // Get duration for config
    // Use ffprobe: ffprobe -v error -show_entries format=duration -of csv=p=0 file.webm
  }

  await browser.close();
}

Convert WebM to MP4

将WebM转换为MP4

Playwright outputs WebM. Convert for better Remotion compatibility:

bash

ffmpeg -i recording.webm -c:v libx264 -crf 20 -preset medium -movflags faststart public/demos/demo.mp4

Playwright输出WebM格式文件。为了更好地兼容Remotion，可进行格式转换：

bash

ffmpeg -i recording.webm -c:v libx264 -crf 20 -preset medium -movflags faststart public/demos/demo.mp4

Interactive Recording

交互式录制

For user-driven recordings where you manually perform actions:

typescript

// Inject ESC key listener to stop recording
async function injectStopListener(page: Page): Promise<void> {
  await page.evaluate(() => {
    if ((window as any).__escListenerAdded) return;
    (window as any).__escListenerAdded = true;
    (window as any).__stopRecording = false;
    document.addEventListener('keydown', (e) => {
      if (e.key === 'Escape') {
        e.preventDefault();
        (window as any).__stopRecording = true;
      }
    });
  });
}

// Poll for stop signal - handle navigation errors gracefully
while (!stopped) {
  try {
    const shouldStop = await page.evaluate(() => (window as any).__stopRecording === true);
    if (shouldStop) break;
  } catch {
    // Page navigating - continue recording
  }
  await new Promise(r => setTimeout(r, 200));
}

Key insight:

page.evaluate()

throws during navigation. Use try/catch and continue - don't treat errors as stop signals.

如需由用户手动执行操作的交互式录制：

typescript

// Inject ESC key listener to stop recording
async function injectStopListener(page: Page): Promise<void> {
  await page.evaluate(() => {
    if ((window as any).__escListenerAdded) return;
    (window as any).__escListenerAdded = true;
    (window as any).__stopRecording = false;
    document.addEventListener('keydown', (e) => {
      if (e.key === 'Escape') {
        e.preventDefault();
        (window as any).__stopRecording = true;
      }
    });
  });
}

// Poll for stop signal - handle navigation errors gracefully
while (!stopped) {
  try {
    const shouldStop = await page.evaluate(() => (window as any).__stopRecording === true);
    if (shouldStop) break;
  } catch {
    // Page navigating - continue recording
  }
  await new Promise(r => setTimeout(r, 200));
}

关键提示：

page.evaluate()

在页面导航时会抛出异常。使用try/catch块并继续录制——不要将错误视为停止信号。

Window Scaling for Laptops

笔记本电脑窗口缩放设置

Record at full 1080p while showing a smaller window:

typescript

const scale = 0.75; // 75% window size
const context = await browser.newContext({
  viewport: { width: 1920 * scale, height: 1080 * scale },
  deviceScaleFactor: 1 / scale,
  recordVideo: { dir: './recordings', size: { width: 1920, height: 1080 } },
});

在显示较小窗口的同时以全1080p分辨率录制：

typescript

const scale = 0.75; // 75% window size
const context = await browser.newContext({
  viewport: { width: 1920 * scale, height: 1080 * scale },
  deviceScaleFactor: 1 / scale,
  recordVideo: { dir: './recordings', size: { width: 1920, height: 1080 } },
});

Cookie Banner Dismissal

Cookie横幅自动关闭

Comprehensive selector list for common consent platforms:

typescript

const COOKIE_SELECTORS = [
  '#onetrust-accept-btn-handler',           // OneTrust
  '#CybotCookiebotDialogBodyButtonAccept',  // Cookiebot
  '.cc-btn.cc-dismiss',                      // Cookie Consent by Insites
  '[class*="cookie"] button[class*="accept"]',
  '[class*="consent"] button[class*="accept"]',
  'button:has-text("Accept all")',
  'button:has-text("Accept cookies")',
  'button:has-text("Got it")',
];

async function dismissCookieBanners(page: Page): Promise<void> {
  await page.waitForTimeout(500);
  for (const selector of COOKIE_SELECTORS) {
    try {
      const btn = page.locator(selector).first();
      if (await btn.isVisible({ timeout: 100 })) {
        await btn.click({ timeout: 500 });
        return;
      }
    } catch { /* try next */ }
  }
}

Call after

page.goto()

and on

page.on('load')

for navigation.

针对常见同意平台的综合选择器列表：

typescript

const COOKIE_SELECTORS = [
  '#onetrust-accept-btn-handler',           // OneTrust
  '#CybotCookiebotDialogBodyButtonAccept',  // Cookiebot
  '.cc-btn.cc-dismiss',                      // Cookie Consent by Insites
  '[class*="cookie"] button[class*="accept"]',
  '[class*="consent"] button[class*="accept"]',
  'button:has-text("Accept all")',
  'button:has-text("Accept cookies")',
  'button:has-text("Got it")',
];

async function dismissCookieBanners(page: Page): Promise<void> {
  await page.waitForTimeout(500);
  for (const selector of COOKIE_SELECTORS) {
    try {
      const btn = page.locator(selector).first();
      if (await btn.isVisible({ timeout: 100 })) {
        await btn.click({ timeout: 500 });
        return;
      }
    } catch { /* try next */ }
  }
}

在

page.goto()

之后和

page.on('load')

事件中调用此函数，以处理页面导航时的Cookie横幅。

重要提示：注入的元素会出现在视频中

Warning: Any DOM elements you inject (cursors, control panels, overlays) will be recorded. For UI-free recordings, use terminal-based controls only (Ctrl+C, max duration timer).

警告： 你注入的任何DOM元素（如光标、控制面板、覆盖层）都会被录制下来。如果需要无UI的录制内容，请仅使用终端控制（如Ctrl+C、最大时长计时器）。

Tips for Good Demo Recordings

优质演示录制技巧

Use slowMo - 50-100ms makes actions visible
Add waitForTimeout - Pause between actions for comprehension
Wait for animations - Use
```
waitForLoadState('networkidle')
```
Match Remotion dimensions - 1920x1080 at 30fps typical
Test without recording first - Debug before final capture
Clear browser state - Use fresh context for clean demos
Dismiss cookie banners - Use comprehensive selector list above
Re-inject on navigation - Cursor/listeners reset on page load

使用slowMo - 50-100ms的延迟可让操作更清晰可见
添加waitForTimeout - 在操作之间添加暂停，方便观众理解
等待动画完成 - 使用
```
waitForLoadState('networkidle')
```
匹配Remotion尺寸 - 通常为1920x1080、30fps
先不录制进行测试 - 在最终捕获前先调试流程
清除浏览器状态 - 使用全新的上下文以获得干净的演示效果
关闭Cookie横幅 - 使用上方的综合选择器列表
页面导航后重新注入 - 页面加载时光标/监听器会重置
