Re-encode the files before joining them.If your files have different video codecs, or pixel formats, or height and width, then you need to re-encode them before you can concatenate the files. I ran this command in my video database folder and here is the output – looks good right? file 'brooklynsfinest_clip_1080p.mp4'Īnd, then you can concatenate them using the concat command we learned about earlier as follows./ffmpeg -f concat -safe 0 -i fileList.txt -c copy mergedVideo.mp4 Concatenate mp4 Files of Different Codecs, Resolutions for f in *.mp4 do echo file \'$f\' > fileList.txt Then you can easily concatenate them as shown above. The first step you need to do here is to find all the mp4/avi/wav files in your directory and add them to a file. This is a commonly asked question and it has to do more with shell scripting than actual FFmpeg usage. Remember, you are not re-encoding in this commandline because you are using the copy command. Here, you are using the concat command to read the list of video files that you created ( fileList.txt) and copy the individual files in that order into an output file called mergedVideo.mp4. ffmpeg -f concat -safe 0 -i fileList.txt -c copy mergedVideo.mp4
Now, you can concatenate them using the following FFmpeg command. each line starts with the keyword file and contains the path of the file within single quotes. In this example, both the files are in the home directory. Here is an example and let us call the list fileList.txt. Then, you need to supply this list to FFmpeg as a commandline parameter. First, you need to create a txt file with the names and paths of all the individual files that you want to concatenate. There are two steps to using this command. That is, they have the same height, width, pixel formats, codecs, etc. You can concatenate these files using the concat demuxer ( documentation) easily if their properties match. Let’s say you have two files file1.mp4 and file2.mp4. Let’s start with the simplest use case which is to concatenate two mp4 files using FFmpeg.
