There is no need to panic if you think the process is complicated. You just have to follow the steps accordingly, and you will have a perfect result every time.

Part 1. Steps to Concatenate MP4 Videos with FFmpeg

There are various ways to concatenate MP4 videos with FFmpeg, but we will provide you a simple and effective process here. So that if you are new to this, you won't feel that it's hard to follow. The process has some complicated steps and commands to enter, so use it at your own risk. Even if you think that this process is hard for you to handle, you can always use the alternative method using Wondershare UniConverter. Here is how to merge mp4 videos using FFmpeg.

Step 1: First, you need to keep all the mp3 files you want to combine in a single folder. For example, the path of my folder is:


Step 2: Then, you need to download the FFmpeg file from this address - Download the version suitable for your computer. For my PC, I downloaded the 64-bit latest version.

Step 3: Next, open the Command Prompt window by right-clicking on the windows icon or you can press Windows + R in your keyboard, type in cmd.exe, and then press Enter to open it.

Step 4: When the command prompt window opens, you need to type in or change the destination folder path of the mp4 files.

Step 5: Next, you need to create a .txt folder that will have a list of all the mp4 files that you want to combine. You need to type in this below command and press Enter:

(for %i in (*.mp4) do @echo file '%i') > mylist.txt

You will see that a mylist.txt file is created in the mp4 folder with a list of all the mp4 files.

Step 6: Finally, you need to type in this below command to combine all the mp4 files by using FFmpeg –

ffmpeg -f concat -i mylist.txt -c copy output.mp4

As the process is just concatenating the files and not re-encoding, it should be done easily with fast speed. If no error message occurs, you will get a final combined video named output.mp4 in the MP4 folder.
