Understanding Vertical Video Platforms and Their Data Structures

What Defines Vertical Video?

Vertical video refers to video content recorded and displayed in a portrait orientation, typically with an aspect ratio of 9:16. This format leverages the natural way users hold smartphones and prioritises full-screen immersive viewing on mobile devices.

How Platforms Like Netflix Are Adopting Vertical Videos

Although Netflix is traditionally a horizontal streaming platform, experimental features and vertical teaser clips are becoming a part of their strategy to engage mobile-first audiences. This shift impacts how data is delivered and structured on the frontend, complicating the extraction process due to dynamic content loading and interactive UI layers.

Data Structures Common to Emerging Vertical Video Platforms

Vertical video platforms typically utilize APIs that deliver video metadata, thumbnails, captions, and streaming links dynamically. Additionally, UI components rely heavily on JavaScript frameworks, requiring scrape techniques that can handle modern Single Page Application (SPA) behaviors.

Challenges in Scraping Streaming Data From Vertical Video Platforms

Dynamic Content Loading and Infinite Scroll

Unlike traditional paginated websites, vertical video platforms commonly use continuous scrolling with dynamic content fetching, demanding scraper designs that can simulate user interactions like scroll events.

Protected Media Streams and DRM

Streaming services often employ DRM (Digital Rights Management) to protect their media streams, restricting direct URL extraction or download. Understanding the limits and legal boundaries is critical to avoid violating platform terms.

Bot Detection, Rate Limiting, and Anti-Scraping Measures

Many platforms deploy bot detection systems and rate limiting, making it difficult to scrape reliably. Adaptive techniques including IP rotation, headless browser stealth modes, and request throttling are essential.

Pro Tip: Employ proxy pools tailored for UK IPs to reduce geo-based blocking and maintain compliance, as outlined in our guide on securing Bluetooth devices, where network security overlaps with scraping strategies.

Technical Toolkit: Essential Tools and Libraries

Headless Browsers for Dynamic Video Pages

Headless browsers like Puppeteer and Playwright allow scraping JavaScript-heavy vertical video pages by emulating full browser environments. These tools can simulate scrolling, clicks, and media events to trigger API calls and load content.

Video Stream Extraction Libraries

Libraries such as youtube-dl (and its forks) can sometimes extract streaming URL manifests. However, for proprietary streaming formats or DRM-protected videos, custom network traffic inspection and reverse engineering may be necessary.

Proxy and IP Rotation Services

To overcome rate limits and geo-restrictions, integrating proxy services that support token-based authentication and dynamic IP rotation is vital. Read more about proxy management strategies in our AI coding solutions comparison.

Step-by-Step Guide: Scraping Vertical Videos with Puppeteer

Setting Up Puppeteer for Vertical Video Platforms

Begin by installing Puppeteer and configuring viewport dimensions compatible with vertical video (e.g., 375 x 667 pixels, mimicking mobile portrait dimensions).

npm install puppeteer

const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch({ headless: true });
  const page = await browser.newPage();
  await page.setViewport({ width: 375, height: 667 });
  await page.goto('https://example-vertical-video-platform.com');
  // Further scraping logic
  await browser.close();
})();

Handling Infinite Scroll to Load More Videos

Infinite scroll can be simulated by evaluating JavaScript to scroll down the page periodically until content load stabilizes.

async function autoScroll(page){
  await page.evaluate(async () => {
    await new Promise((resolve) => {
      let totalHeight = 0;
      const distance = 100;
      const timer = setInterval(() => {
        window.scrollBy(0, distance);
        totalHeight += distance;
        if(totalHeight >= document.body.scrollHeight){
          clearInterval(timer);
          resolve();
        }
      }, 200);
    });
  });
}

await autoScroll(page);

Extracting Video Metadata and Stream URLs

Use DOM selectors or intercept network requests to capture relevant metadata such as titles, descriptions, likes, comments, and video streaming URLs.

For example, you could intercept API responses fetching video data like this:

page.on('response', async (response) => {
  const url = response.url();
  if(url.includes('/api/videos')) {
    const json = await response.json();
    // Process video metadata here
  }
});

Scaling and Automating Data Extraction Pipelines

Scheduling Jobs and Managing Rate Limits

Utilising a job scheduler like cron combined with queues for concurrency control helps avoid rate-limiting issues. APIs may require adaptive timings based on user agent and IP.

Data Cleaning and Structuring for Analytics

Extracted data often requires cleaning — for example, normalizing timestamps, decoding JSON payloads, and formatting text fields — before integration with analytics or ML pipelines.

Integration with Data Lakes and Cloud Storage

For production workflows, push scraped data into scalable storage solutions such as AWS S3 or databases like MongoDB to pipeline into downstream analytics or competitor tracking applications. Learn from our case study on AI-driven video processing for future quantum media integration.

Legal and Ethical Considerations in Video Data Scraping

Understanding Copyright and Terms of Service

Scraping video content may violate copyright laws or platform-specific terms of service. Always review platform policies and seek legal counsel when in doubt.

Ensuring Compliant Data Collection

Collect only publicly available data and avoid downloading protected stream content. For UK-specific legal guidance, our analysis on EU antitrust regulations offers principles applicable to data ethics.

Respecting User Privacy

Avoid scraping personally identifiable information (PII) or sensitive metadata unless explicitly permitted. Data anonymization is recommended to maintain trustworthiness.
