How can I fade audio when scrolling past video player?

[J.D]

So use the code I posted above and if you want to resume once it gets into viewport again then:

$w.onReady(() => {
    $w("#videoPlayer1").onViewportLeave(() => $w("#videoPlayer1").pause());
    $w("#videoPlayer1").onViewportEnter(() => $w("#videoPlayer1").play());
})
