We'll take a look at how to use the seeking parameter -ss, but you can also use other commands such as the trim filter.
Cut/trim a video with FFmpegįFmpeg offers different commands that you can use to split up a video.
We'll finish off by looking at how you can achieve the same results using Shotstack - a cloud-based video editing API. We'll look at some FFmpeg commands that you can use to trim a video into different parts and then see how you can take different videos and concatenate them into a single video. We'll see how to do exactly that using FFmpeg - a command-line utility that can be used to create, edit and process different types of media. When editing a video, you might want to cut out some parts or you might want to stitch together different videos by cutting sections from different sources and concatenating them into a single video. We get it with the previously defined helper getVideoInfo.A common feature of video editing applications is the ability to cut/trim videos. Let’s create a helper function that gets the duration for us: export const getVideoInfo = (inputPath: string) => `])Īs was the case with the previous function, we must first know the length of the video in order to calculate when to extract each frame. ffprobe is a tool that lets us get the metadata of a video, among other things. In order to get the duration of the video, we can use ffprobe, which comes with FFmpeg. For this, of course, we must first get the video duration. In order for the fragment to be a meaningful and representative sample of the video content, it is best if we get it from a point somewhere around 25–75 percent of the total length of the video. The video fragment preview is pretty straightforward to create all we have to do is slice the video at the right moment. I will be using Childish Gambino’s “ This is America” video for testing purposes. Now that we know what tools to use for video manipulation from within Node.js runtime, let’s create the previews in the formats mentioned above. env file: FFMPEG_PATH="D:/ffmpeg/bin/ffmpeg.exe"īoth paths have to be set if they are not already available in our $PATH. ) or by our providing the paths to the executables through the environment variables. The fluent-ffmpeg library depends on the ffmpeg executable being either on our $PATH (so it is callable from the CLI like: ffmpeg.

The installation process is pretty straightforward if you are on Mac or Linux machine. Also, in our examples, there won’t be anything too fancy going on. It also implements many useful features, such as tracking the progress of a command and error handling.Īlthough the commands can get pretty complicated quickly, there’s very good documentation available for the tool. The library, available on npm, generates the FFmpeg commands for us and executes them. under a wide variety of build environments, machine architectures, and configurations.īoasting such an impressive resume, FFmpeg is the perfect choice for video manipulation done from inside of the program, able to run in many different environments.įFmpeg is accessible through CLI, but the framework can be easily controlled through the node-fluent-ffmpeg library.

It is also highly portable: FFmpeg compiles, runs, and passes our testing infrastructure FATE across Linux, Mac OS X, Microsoft Windows, the BSDs, Solaris, etc. No matter if they were designed by some standards committee, the community or a corporation. It supports the most obscure ancient formats up to the cutting edge. In the documentation, we read:įFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. Manipulating a video with Node.js itself would be extremely hard, so instead we are going to use the most popular video manipulation tool: FFmpeg. We are going to take a closer look at how to implement both of these approaches. Another popular way of creating a preview is to take a few frames from a video and make a slideshow. YouTube, for instance, plays a 3- to 4-second excerpt from a video whenever users hover over its thumbnail. Generating video previews with Node.js and FFmpegĮvery website that deals with video streaming in any way has a way of showing a short preview of a video without actually playing it.
