How to record smooth page scrolling from the screen?

Question

Google Chrome

I stumbled upon the site devnow.ru
In their "Media Sites" section, when you hover over the site, a video starts in which the site scrolls terribly smoothly, I think there are 50 frames.
I can't figure out how to make a video like this. If you scroll the site with the down arrow, then it scrolls twitchy, in jerks. Even with all sorts of extensions like smooth scrolling, the number of frames is 30-40 (+ different sites get different scrolling speeds, I need the same for all sites).
I get the same smooth scrolling only from the touchpad, but I need a uniform scroll, without stops (it won’t work on the touchpad)
Maybe there is some kind of program for this? Or an extension?

danyfir , in this particular video, the editing is clearly stupid, since the fade-out effects are visible at the transition from section to section.
But in principle, you can record any level of video https://www.youtube.com/watch?v=Q8rqxvDv8jc&featur...
Smooth scrolling is achieved by scrolling from the keyboard, and not by the mouse wheel. We put it on the record, pressed the down arrow, the record went at the desired speed.
In 5 minutes, I uploaded using SimpleScreenRecorder (under Linux, but I think you can record video from the screen on any system), which writes the screen area and plugin for FF https://addons.mozilla.org/en/firefox/addon/yass-we / , which allows you to adjust the scroll speed, smoothness and step size.
One of the settings that you need to turn off in any editor is "frame skip".
