SVG animation delay (add it) and glitch on restarting animation (stop it)

#1

I’m quite a novice at SVG and animations and ran into an issue I can’t solve. I’m hoping you can help, as the tutorials I read about delaying the second animation (begin = “3s”) doesn’t seem to work for delaying the blur effect. Thank you in advance.

1 Adding A Delay

The scroll down animation is working as intended. The scroll up animation refuses to delay until the logo has moved into place before bluring-in.

2 Stopping the Glitch

For some reason the animation plays smoothly for (1) round, then glitches each scroll up and down. Anyone seen this before?

Snippets Below, Pen Here: https://codepen.io/brittany-golden/pen/OGxbxq

jQuery(document).ready(function($) {

	// Smooth OUT
	$('#smooth-logo').waypoint(function(direction) {
		
		if (direction === 'down') {

			$('.fadeMe').addClass('blur-in-fwd');
			$('.fadeMe').removeClass('blur-in-bkw');
			$('#smooth-logo').addClass('slideLeft');
			$('#smooth-logo').removeClass('slideRight');
			$('#animOut').get(0).beginElement(); // restart the animation

		} else if (direction === 'up') {  

			$('.fadeMe').addClass('blur-in-bkw');
			$('.fadeMe').removeClass('blur-in-fwd slide-right');
			$('#smooth-logo').addClass('slideRight');
			$('#smooth-logo').removeClass('slideLeft');
			$('#animIn').get(0).beginElement(); // restart the animation
		}
	}, 
		
	{ offset: '0%' });
	
});
