Needed to enable smooth scrolling of a long page in Chrome for a demo video.
Use Automator > Quick Action > Run AppleScript with:
tell application "Google Chrome"
set theTab to active tab of front window
execute theTab javascript "
const total = document.body.scrollHeight - window.innerHeight;
let pos = 0;
const i = setInterval(() => {
window.scrollBy(0, 2);
pos += 2;
if (pos >= total) clearInterval(i);
}, 10);
"
end tell
or via bookmarklet (ie Chrome bookmark) - though this means you have to click on the bookmark (less sophisticated for video recording):
javascript:(function(){ const total = document.body.scrollHeight - window.innerHeight; let pos = 0; const i = setInterval(() => { window.scrollBy(0, 2); pos += 2; if (pos >= total) clearInterval(i); }, 10);})();
