What can I do to prevent the responsive background video set to 'cover' from jumping with each page load?

I am working towards a certain objective in this project. A vibrant bouncing cover animation that plays every time a page loads is what I want to introduce. I’m focused on investigating the techniques and strategies that can enable me to produce this captivating animation effect. I would be appreciative of any advice or pointers on how to create this exciting and dynamic page load animation.

You can use a number of approaches to ensure smooth loading and keep a consistent visual presentation to stop a responsive background video set to “cover” from acting jumpy with each page load:

1. Watch the Video First

Use the preload attribute in the video> tag to reduce the chance that the video will load a little bit later than other content. Encouraging the video to preload, improves synchronization while the page loads.

<video preload="auto" autoplay loop muted>
   <source src="your_video.mp4" type="video/mp4">

2. Determine on Fixed Dimensions

Don’t forget to check that the video’s container has set dimensions. As the video loads, this helps the layout stay stable. To determine the container’s dimensions, use CSS:

.video-container {
   width: 100%;
   height: 100vh; /* Alternatively, specify a particular height */
   overflow: hidden;

video {
   width: 100%;
   height: auto;

3. Use an image as a placeholder

Consider using a placeholder image that resembles the first frame of the video to guarantee a seamless user experience. This avoids sudden visual changes before the start of video playback. When the video begins to play, align the image beneath it and then remove it:

1. For HTML

<div class="video-container">
   <img class="video-placeholder" src="placeholder_image.jpg" alt="Video Placeholder">
   <video autoplay loop muted>
      <source src="your_video.mp4" type="video/mp4">

2. CSS

.video-placeholder {
   position: absolute;
   top: 0;
   left: 0;
   width: 100%;
   height: 100%;

video {
   position: relative;
   z-index: -1;

4. Make Sure the Proper Styling Is Done

Verify that the HTML coding and CSS style are in the right order. Use the proper CSS to put the video element after the content.

5. Optimise video size and format

Use web-compatible video formats, such as MP4 with the H.264 codec. Additionally, the video’s compression should be optimized to find a balance between file size reduction and quality retention.

6. Gain from the Canplay Event

To control the video’s playback state, use JavaScript. Use the canplay event to start playing a video, ensuring that it is completely prepared for smooth playback:

const video = document.querySelector('video');
video.addEventListener('canplay', () => {

These are the steps to take in order to prevent the responsive background.
