Web Crawling vs. Web Scraping - What's the Difference?
Web scraping is about extracting the data from one or more websites. While Crawling is about finding or discovering URLs or links on the web.
Usually, in web data extraction projects, you need to combine crawling and scraping. So you first crawl - or discover - the URLs, download the HTML files, and then scrape the data from those files. This means you extract data and do something with it, like store it in a database or further process it.

I have a question. With an image or video, what data can we extract from these? Is just file size, movie length, frames, colour wheels?

Please answer my question. What is the difference between web scraping and parsing? Thank you in advance.

Parsing is about feature extraction from HTML -- e.g., Finding the H1 tag by searching the HTML for all H1 elements on a given page. For example, you might crawl, then queue up a scraper which will fetch those URLs, and THEN that scraper will then parse the HTML for features and output a document in a structure that you like. That may be the title, a description, maybe a list of authors (for a blog), or even a collection of images on the website. People use the terms interchangeably, but often in programming ... parsing means taking a large string of text and identifying the structure of that string of text.
