Overview

The node provides video processing capabilities using FFmpeg, focusing here on the Video - Merge operation. It merges multiple video sources into a single output video file in a specified format. This is useful for combining clips from different sources or formats into one continuous video.

Common scenarios include:

Combining several short video clips into one longer video.
Merging videos from URLs and binary data inputs.
Creating compilations or highlight reels from multiple video files.

Example: You have three video URLs or binary video files and want to merge them into a single MP4 video for easier sharing or further processing.

Properties

Name	Meaning
Video Sources	A collection of video inputs to merge. Each source can be either:
	- URL: Provide a direct link to a video file (e.g., `https://example.com/video.mp4`).
	- Binary Data from Previous Node: Use binary video data from a prior workflow node.
Output Format	The desired output video format after merging. Options are: `MP4`, `AVI`, or `MOV`.

Output

The node outputs a binary video file containing the merged video.
The binary data is available under the property named data by default.
The output filename corresponds to the merged video file with the chosen extension (.mp4, .avi, or .mov).
The JSON output contains metadata about success and operation but no direct video data; the actual video is in the binary output.

Dependencies

Requires FFmpeg installed and accessible in the environment where n8n runs.
No external API keys or services are needed; all processing is local.
Uses internal helper utilities for resolving input paths and cleaning temporary files.

Troubleshooting

No binary data found error: When using binary input sources, ensure the specified binary property exists and contains valid video data.
File not found errors: For URL sources, verify the URLs are accessible and correct. For binary sources, confirm previous nodes provide the expected data.
Unsupported format or codec issues: Ensure FFmpeg supports the input video formats and the selected output format.
Temporary file cleanup failures: Occasionally, old temp files may not delete immediately; this usually does not affect processing but may require manual cleanup.
Operation did not produce an output: If merging fails silently, check input validity and that at least two video sources are provided.
