Pause offscreen videos and gently fade in visible ones for smooth, efficient browsing.
Exactly what this script does is limit how many autoplaying videos can buffer at once on and off the screen based on what's your viewport's threshold. It will begin as videos load in on the page. It will pause and reset the duration of said videos so no worries of a video playing mid playthrough. I have it set to dim paused videos and fade them back in as they play. Best part after you're are done watching a video it will stop playing once scrolled out of view! This saves SO much CPU. I looked everywhere for something like this couldn't find it so I made with ChatGPT's help! Side note I got inspired to make this script due to 2 features included in hdyzen's Redgifs Embed Tweaks (RET). Their script pairs well with mine.
Rejoice and enjoy those specific subreddits (you know which ones) on infinite scroll and it NOT kill your CPU/stop loading redgifs videos altogether! OR You could also go to redgifs main site and watch there one video at a time there too!
