# Website Scroll Video vs Chrome scroll-recording extensions

> Scroll-recording Chrome extensions such as Scroll Capture compared with a URL renderer: where each runs, what decides the smoothness, private pages, mobile layouts and pop-ups.

**The short answer:** Scroll-recording extensions such as Scroll Capture automate the scroll inside your own Chrome tab and record it, so they can capture pages you are signed in to and anything on localhost. Because they record in real time on your machine, smoothness and resolution depend on your computer and screen. Website Scroll Video renders from the URL on its servers instead, so the frame rate is locked, the output can be up to 4K from any device, pop-ups are removed automatically and nothing needs installing, but it can only open public pages.

## Choose Chrome extensions if

- The page is behind a login, on localhost or on a private network.
- You want to script clicks, typing or custom CSS during the take.
- You prefer a tool that stays inside your own browser.

## Choose Website Scroll Video if

- You want a locked 60 fps regardless of how busy your machine is.
- You need output larger than your screen, up to 4K, or an exact size.
- You are on a tablet, a phone or a browser that is not Chrome.
- You want pop-ups removed, frames and backgrounds added, with no install.

“Not listed” means Chrome extensions’s page does not say.

## How scroll-recording extensions work

An extension uses Chrome’s tab capture to record the page you are looking at while a script scrolls it. Scroll Capture, one of the longest-running, describes itself as a tool for designers and developers making portfolio captures: its scroll eases in and out, can calculate the duration from the scroll distance, and it can also script mouse events, text input, custom CSS and zoom. Its listing shows about 30,000 users. Newer ones, such as ScrollCinema, offer free tiers with paid upgrades for styles and viewport options.

Because the capture happens in your tab, an extension sees exactly what you see, including pages you are signed in to. That is their real advantage over any URL-based tool.

## The trade-off of recording locally

- **Smoothness depends on your machine.** The scroll is automated, but it is still recorded in real time. A heavy page, a busy laptop or a high-refresh display can drop frames or space them unevenly. See [why scroll recordings stutter](https://websitescrollvideo.com/guides/fix-jerky-scrolling-in-screen-recordings/).
- **Size depends on your screen.** A tab can only be recorded at the size it is drawn. A 4K export from a laptop, or a 1080 × 1920 one from a desktop browser, means emulation and scaling.
- **Your browser is in the shot.** Your extensions, your cookie choices and your signed-in state are all part of what the page shows.
- **Chrome only, desktop only.** Extensions do not run in Safari or on a phone.

## What a renderer does differently

Website Scroll Video opens a fresh browser on its servers for each page, at desktop, tablet or phone width. It removes cookie banners, chat launchers and modals, reads the page at double density, then calculates every frame of the scroll at a locked 24, 30 or 60 fps. Your machine only shows the preview. You can work from an iPad, change the shape and export again, and the output can be bigger than any screen you own, up to 4K or any size up to 4096 px.

The cost of that is reach: a renderer is an anonymous visitor, so a page behind a login shows its login screen. For those pages an extension or a screen recorder is the right tool.

## Questions

### What is the best Chrome extension for recording a scrolling website?

Scroll Capture is one of the most established, with automated eased scrolling and MP4, WebM or MKV output. For public pages, a URL renderer such as Website Scroll Video avoids the install and records at a locked frame rate independent of your machine.

### Can a Chrome extension record a page I am logged in to?

Yes. Because it records your own tab, it sees everything you can see. A URL renderer cannot, because it opens the page as a signed-out visitor.

### Why is my extension’s scroll recording choppy?

The recording happens in real time on your computer, so a heavy page or a busy machine drops frames. Close other tabs and apps, preload the page, and record at 60 fps, or render the video from the URL instead.
