Node.js Fluent-FFMPEG Example to Trim or Cut Videos Based on Start & End Time in Command Line

Welcome folks today in this blog post we will be using the fluent-ffmpeg library to trim or cut videos based on start and end time in command line using javascript. All the full source code of the application is shown below.

Get Started

In order to get started you need to install the below library using the npm command as shown below

npm i fluent-ffmpeg

After that you need to make an index.js file and copy paste the following code

index.js

const ffmpeg = require('fluent-ffmpeg')

ffmpeg({source:'video.mp4'})
.setStartTime('00:01:10')
.duration(50)
.on('start',(commandLine) => {
    console.log("Processing Started")
})
.on('error',(err) => {
    console.log("error takes place")
})
.on('end',() => {
    console.log("processing done")
})
.saveToFile("cut.mp4")

const ffmpeg = require('fluent-ffmpeg')

ffmpeg({source:'video.mp4'})

.setStartTime('00:01:10')

.duration(50)

.on('start',(commandLine) => {

console.log("Processing Started")

})

.on('error',(err) => {

console.log("error takes place")

})

.on('end',() => {

console.log("processing done")

})

.saveToFile("cut.mp4")

As you can see we are importing the fluent-ffmpeg library and then we are calling it and passing the source property where we provide the path of the input video file and then we are calling the setStartTime() to trim or cut the video at the specified time duration and then we are using the duration() method to trim the video for x seconds. And then we are listening on various events such as start ,error and end. And lastly we are saving the video file with custom filename.
