The following code stitches four videos without re-encoding them. You can also join videos with the concat protocol.

After the file is generated, you can then stitch the listed video with the command we used earlier: $ ffmpeg -f concat -i videos.txt -c copy output9.mp4 Merge videos with the concat protocol The above will create a file videos.txt with a list of files with the extension. $ for f in *.mp4 do echo 'file ' $f'' > videos.txt done They will be listed according to LC_COLLATE. To determine the order that the videos will be listed, you can name them alphabetically or numerically. If you have a large number of videos in a directory, it might be easier to write a command that will create a file with the list of videos for you before concatenating them. $ ffmpeg -f concat -i videos.txt -c copy output8.mp4 Merge all videos in a directory with FFmpeg using concat demuxer With that done, if you run the following command, the videos listed in that file will be merged, according to the order they are listed. You can add comments to the file, they will be ignored by the demuxer. To merge videos using the concat demuxer, first create a text file with a list of videos you want to join. Merge a list of videos with FFmpeg using concat demuxer We are going to look at how to concat videos that share the same codec, for the latter, please refer to the FFmpeg concatenate documentation.įor videos that have the same codec, you can concatenate them using concat demuxer or concat protocol. There are several ways that videos can be concatenated, depending on whether the individual videos share the same codec or not. When using FFmpeg to merge a series of video clips, the process is called concatenation, or concat for short. We'll look at two different ways to use FFmpeg and we'll end by looking at how you can achieve the same results using Shotstack, a cloud-based video editing API.

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. But how would you go about this if you wanted to do this with code? This process is easily done within a video editing application by dragging and dropping different video clips and placing them along a timeline. One of the core concepts of video editing involves stitching or merging together different clips to create a narrative or story.
