Hello guys, In this article we will learn how to control video with ScrollTrigger using GASP ScrollTrigger
Step 1 — Creating a New Project
In this step, we need to create a new project folder and files(index.html, style.css, main.js) for creating an awesome video animation on scroll. In the next step, you will start creating the structure of the webpage.
Step 2 — Setting Up the basic structure
In this step, we will add the HTML code to create the basic structure of the project.

<body>
</body>
</html>This is the base structure of most web pages that use HTML.
Add the following code inside the <body> tag:
<div id="background-container" class="background-container">
<div id="video-container" class="video-container">
<video src="bg.mp4" type="video/mp4" id="bgVideo"></video>
</div>
</div>
<div id="scroll-container" class="scroll-container">
<section id="step0" class="step">
<div>
<h3>Hello</h3>
</div>
</section>
<section class="step">
<div>
<h3>My</h3>
</div>
</section>
<section class="step">
<div>
<h3>Name</h3>
</div>
</section>
<section class="step">
<div>
<h3>Is</h3>
</div>
</section>
<section class="step">
<div>
<h3>Rahul</h3>
</div>
</section>
<section class="step">
<div>
<h3>jangid</h3>
</div>
</section>
<section class="step">
<div>
<h3>Thanks :)</h3>
</div>
</section>
</div>In the next steps, we will add the JS library and main.js file
Step 3 — Add Gsap ScrollTrigger and js file
<!-- Gsap ScrollTrigger--> <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.6.1/gsap.min.js" integrity="sha512-cdV6j5t5o24hkSciVrb8Ki6FveC2SgwGfLE31+ZQRHAeSRxYhAQskLkq3dLm8ZcWe1N3vBOEYmmbhzf7NTtFFQ==" crossorigin="anonymous" referrerpolicy="no-referrer"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.6.1/ScrollTrigger.min.js" integrity="sha512-Q+G390ZU2qKo+e4q+kVcJknwfGjKJOdyu5mVMcR95NqL6XaF4lY4nsSvIVB3NDP54ACsS9rqhE1DVqgpApl//Q==" crossorigin="anonymous" referrerpolicy="no-referrer"></script> <!-- --> <script src="main.js" charset="utf-8"></script>
Step 4 — Adding Styles for the Classes
In this step, we will add styles to the section class Inside style.css file
* {
padding: 0;
margin: 0;
box-sizing: border-box;
font-family: 'IBM Plex Sans', sans-serif;
}
html {
height: 100%;
}
body {
height: 100%;
overflow-x: hidden;
overflow-y: scroll;
}
.background-container {
position: fixed;
display: flex;
bottom: 0px;
left: 0px;
width: 100%;
height: 100vh;
overflow: hidden;
flex-direction: row;
align-items: center;
}
.video-container {
flex: 1;
width: 100%;
height: 100%;
display: flex;
justify-content: center;
}
#bgVideo {
flex: 1;
background-color: #000;
opacity: 1;
visibility: visible;
}
.scroll-container {
overflow: hidden;
}
.step {
display: flex;
flex-direction: column;
justify-content: flex-end;
position: relative;
height: 100vh;
width: 100%;
}
.step > div {
display: flex;
align-content: center;
flex-direction: column;
align-items: center;
justify-content: center;
font-weight: 700;
font-size: 40px;
text-shadow: 2px 2px #000;
height: 100vh;
width: 100%;
color: #fff;
opacity: 1;
}Step 5 — Adding Js Code
In the final step we have to do code for main.js
gsap.registerPlugin(ScrollTrigger);
const bgVvideo = document.querySelector("#bgVideo");
bgVideo.pause();
bgVideo.currentTime = 0;
let sections = gsap.utils.toArray(".step");
sections.forEach((step, i) => {
ScrollTrigger.create({
trigger: step,
start: "bottom bottom",
end: "+=1000",
pin: true,
anticipatePin: 1,
});
gsap.fromTo(bgVideo, { currentTime: 3 * i }, {
scrollTrigger: {
trigger: step,
scrub: 2,
start: "top bottom",
end: "bottom bottom",
},
currentTime: 3 * (i + 1),
duration: 1,
ease: "none",
});
});
gsap.to("#bgVideo", {
scrollTrigger: {
scrub: true
},
scale: 1.5
})#Final Result
