ffmpegvideomergeconcatenate

FFmpeg is a powerful command-line tool for processing multimedia files. A common use case is merging multiple video files into a single file. This guide will show you how to do this easily.

Prerequisites

Before starting, make sure you have:

  • FFmpeg installed on your system
  • Multiple video files you want to merge

Basic Command

The basic command to merge videos is:

ffmpeg -f concat -safe 0 -i filelist.txt -c copy output.mp4

This command uses a text file (filelist.txt) that contains the list of video files to be merged. Each line in the file should contain the path to a video file:

file 'video1.mp4'
file 'video2.mp4'
file 'video3.mp4'

Advanced Options

If you need more control over the output, you can use additional options. For example, you can specify the video codecs and quality:

ffmpeg -f concat -safe 0 -i filelist.txt -c:v libx264 -crf 23 -c:a aac -b:a 192k output.mp4

This command uses the H.264 codec for video and the AAC codec for audio with a bitrate of 192 kbps.

Conclusion

This guide has shown you how to merge multiple video files into a single file using FFmpeg. With these commands, you can easily handle video merging tasks in your multimedia projects.
