Part 1. Why You Need FFmpeg to Combine Videos
Although video merging is mostly done in traditional video editors, the steep learning curve and high hardware requirements of these tools can be limiting for most amateur editors, since they are generally not beginner-friendly and resource-heavy.
As such, command-based multimedia programs take the cake if you are looking for an easier-to-use video merger that doesn’t rely on powerful hardware. In this case, we highly recommend using FFmpeg to join videos. Since it is fully command-based software, you can perform virtually any multimedia task, including video encoding, format conversion, batch processing, and use it as a video merger tool.
Unfortunately, FFmpeg has its limits in terms of the commands you need to learn to use it effectively. As such, this article will provide exactly that, giving our readers the inputs they need to make video combining easier.

Part 2. Step-by-Step Workflow to Use FFmpeg to Combine Videos
Given the strengths of using FFmpeg over traditional video editors to combine files, the biggest obstacle you face is learning the right command-line options. As such, this guide aims to provide exactly that, offering the input you need when using FFmpeg to concatenate video files.
In addition to the command-line, we also provided detailed, step-by-step instructions for using FFmpeg to merge your video files into a single media file. Please read our guide to learn how.
First, create a new text file and list the videos you want to combine. Name it as list.txt.

When choosing the video files you want to merge, list them down by following this format:
file 'video1.format'
file 'video2.format'
file 'video3.format'
Open your computer’s Command Prompt or Terminal.
In your device’s command prompt, write the following command line: ffmpeg -f concat -safe 0 -i list.txt -c copy output.format
Make sure to edit the output.format line to how you want to save your merged video file. Once the file type is set, press Enter.

When done properly, following these steps will allow FFmpeg to combine the audio and video of the files listed in the text document. As such, it is very important to remember the name and format you have selected for the new output file.
