Slider animate on scroll for 1st slide

Hi I have got individual slides animating when they are slid. The issue is I want the first slide which is by default in view to animate when a user scrolls down to the slider, at the moment there is no animation until I press next then go back and it works as normal.

Is there a way to get the first slide to animate when the user scrolls down to it? I tried scroll animations on elements in 1st slide but it was janky as I think its effecting the main animation I set up for the slides.
