How to Edit Videos with Vue: A Step-by-Step Tutorial89

Vue is a progressive JavaScript framework that is widely used for building user interfaces. It is known for its simplicity, flexibility, and performance. However, Vue is not just limited to building static user interfaces. It can also be used to create interactive and dynamic applications, including video editors.

In this tutorial, we will show you how to use Vue to edit videos. We will start by setting up a basic Vue project and then we will add the necessary libraries for video editing. Finally, we will build a simple video editor that allows you to trim, cut, and merge videos.

Prerequisites

Before you start, make sure you have the following installed:*
* npm
* Vue CLI

Setting up the Project

To set up a new Vue project, open your terminal and run the following command:```
vue create video-editor
```

Once the project is created, navigate to the project directory and install the necessary libraries for video editing:```
cd video-editor
npm install vue-video-editor
```

Building the Video Editor

Now that we have the necessary libraries installed, we can start building the video editor. Let's start by creating a new Vue component for the video editor:```
//

import VideoPlayer from "./";
import Controls from "./";
import { ref } from "vue";
export default {
components: { VideoPlayer, Controls },
setup() {
// Create a ref to store the video source
const videoSrc = ref("");
// Create a ref to store the playing state
const isPlaying = ref(false);
return { videoSrc, isPlaying };
},
};

```

In this component, we have a video player and a set of controls. The video player component is responsible for playing the video, while the controls component allows the user to control the video playback.

Next, we need to create the video player component:```
//




import { ref, watchEffect } from "vue";
export default {
props: {
videoSrc: String,
},
setup(props) {
// Create a ref to store the video element
const videoRef = ref(null);
// Create a ref to store the video duration
const duration = ref(0);
// Watch the video source prop
watchEffect(() => {
// If the video source changed, load the new video
();
}, []);
// Listen to the video metadata loaded event
const onLoadMetadata = () => {
// Update the duration ref with the video duration
= ;
};
// Listen to the video play event
const onPlay = () => {
// Set the isPlaying ref to true
= true;
};
// Listen to the video pause event
const onPause = () => {
// Set the isPlaying ref to false
= false;
};
return { videoRef, duration };
},
};

```

In this component, we have a video element that is bound to the videoSrc prop. We also listen to the video metadata loaded event to get the video duration. Finally, we listen to the video play and pause events to update the isPlaying ref.

Next, we need to create the controls component:```
//

Play/Pause



import { ref, watchEffect } from "vue";
export default {
// Emit an event when the play/pause button is clicked
emits: ["playPause"],
setup() {
// Create a ref to store the current time
const currentTime = ref(0);
// Watch the current time ref
watchEffect(() => {
// If the current time changed, seek the video to the new time
= ;
}, [currentTime]);
// Create a method to play or pause the video
const playPause = () => {
// If the video is playing, pause it
if () {
();
} else {
// If the video is paused, play it
();
}
// Emit the playPause event
this.$emit("playPause");
};
// Create a method to seek the video to a specific time
const seek = (e) => {
// Update the current time ref with the new time
= ;
};
return { currentTime, playPause, seek };
},
};

```

In this component, we have a play/pause button and a range input that allows the user to seek the video to a specific time. We also listen to the range input's input event to update the current time ref.

Finally, we need to register the video editor component in the main Vue instance:```
//
import Vue from "vue";
import App from "./";
("video-editor", video-editor);
new Vue({
render: (h) => h(App),
}).$mount("#app");
```

That's it! We have now built a simple video editor using Vue. You can now use this editor to trim, cut, and merge videos.
