Introduction
Today, video animations are widely used in web design to enhance user experience. One of the best tools for creating these animations is the Greensock Animation Platform or GSAP. This library allows you to easily create smooth and attractive video animations on your web pages.
GSAP is a very powerful tool that allows you to have complete control over the timing and characteristics of your animations. This library provides you with specific and simple capabilities that let you create complex and professional animations tailored to your needs.
In this article, we will explore how to use GSAP to create video animations during page scroll. This type of animation offers users a fun and interactive experience from your website, resulting in a better overall experience.
Getting Started
Before starting coding, make sure to properly include the GSAP library in your web project. You will also need the ScrollTrigger tool to effectively manage your scroll animations.
Sample Video Animation Code with GSAP
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<title>Video Animation with GSAP</title>
</head>
<body>
<div class="video-container">
<video src="your-video.mp4" muted autoplay playsinline></video>
</div>
<script>
gsap.registerPlugin(ScrollTrigger);
gsap.to(".video-container video", {
scrollTrigger: {
trigger: ".video-container",
start: "top center",
end: "bottom top",
scrub: true
},
scale: 1.5,
opacity: 0
});

Line-by-Line Code Explanation
<!DOCTYPE html> This line indicates the document type, specifying that this is an HTML document. <html lang="en"> This tag defines the language of the page as English. <head> This section includes metadata about the page, including necessary library imports. <meta charset="UTF-8"> This specifies the character encoding for the document as UTF-8. <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.11.0/gsap.min.js"></script> This line imports the GSAP library. <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.11.0/ScrollTrigger.min.js"></script> This line imports the ScrollTrigger plugin. <div class="video-container"> This element serves as a container for the video. <video src="your-video.mp4" muted autoplay playsinline></video> This line embeds a video with no audio that plays automatically and is designed for mobile responsiveness. gsap.registerPlugin(ScrollTrigger); This line registers the ScrollTrigger plugin for use in your project. gsap.to(".video-container video", { ... }); This initiates the animation using GSAP, scaling the video up and fading it out as the user scrolls.
