Time-Lapse Photography Tutorial337

Time-lapse photography is a technique that captures a series of images over a period of time, then plays them back at a faster speed to create the illusion of motion. This can be used to create stunning videos of everything from sunsets to traffic patterns.

In this tutorial, we'll build a simple time-lapse photography app using . We'll use the webcam API to capture images, and the library to play them back.

Prerequisites

To follow along with this tutorial, you'll need:
A computer with a webcam
installed
A text editor

Step 1: Create a new project

Open your terminal and run the following command to create a new project:```
vue create time-lapse
```

This will create a new directory called `time-lapse`. Navigate into this directory and install the library:```
cd time-lapse
npm install
```

Step 2: Configure

In your `` file, import Vue and the library:```
import Vue from 'vue'
import videojs from ''
```

Next, create a new Vue instance and mount it to the `#app` element in your HTML:```
new Vue({
el: '#app',
data: {
video: null,
images: [],
interval: 1000, // 1 second
isRecording: false,
},
methods: {
startRecording() {
= true
= videojs('video')
setInterval(() => {
()
}, )
},
stopRecording() {
= false
()
()
},
captureImage() {
const canvas = ('canvas')
=
=
const context = ('2d')
(, 0, 0)
(())
},
createVideo() {
const video = ('video')
=
=
for (const image of ) {
const img = ('img')
= image
(img)
}
const blob = new Blob([video], { type: 'video/mp4' })
const url = (blob)
(url)
()
},
},
})
```

Step 3: Create the HTML template

In your `` file, add the following HTML:```

Start
Stop
```

Step 4: Run the app

Run the following command to start the app:```
npm run serve
```

Open your browser to `localhost:8080` and click the "Start" button. The app will start capturing images from your webcam. Once you've captured enough images, click the "Stop" button to create the video.

Conclusion

In this tutorial, we built a simple time-lapse photography app using . We learned how to use the webcam API to capture images, and the library to play them back. You can use this app to create stunning videos of everything from sunsets to traffic patterns.
