n8n ffmpeg usage instructions - merge multiple videos from URL example

This example demonstrates how to merge multiple video files from URLs into a single video using n8n and FFmpeg. Considering that the video files are in MP4 format and have the same codec and resolution. In this example we assume that we have a /data folder mounted as a volume in the n8n container to store temporary files.

1. Create a new workflow in n8n.
2. Add a "HTTP Request" node to download a video file, choose "GET" method and provide the video URL, Options - Response Format: File.
3. Add a "Read / Write files From Disk" node to read the downloaded file, set Operation to "Write file to disk", File and path name: /data/part_{{$itemIndex}}.mp4.
4. Add a "Execute command node" to generate a text file with the list of videos to merge, set Command to:

for f in /data/part_*.mp4; do echo "file '$f'" >> /data/list.txt; done

or

ls -1v /data/part*.mp4 | awk '{print "file \x27" $0 "\x27"}' > /data/list.txt

5. Add another "Execute command" node to merge the videos using FFmpeg, set Command to:

ffmpeg -f concat -safe 0 -i /data/list.txt -c copy /data/output.mp4

6. Add a final "Read / Write files From Disk" node to read the merged video file, set Operation to "Read file from disk", File path: /data/output.mp4.
