Overview

This node provides various ffmpeg-related video processing functionalities within n8n. Specifically, for the "Video Processing" resource and the "Combine Audio To Video" operation, it allows users to merge an audio track with a video file. This is useful when you have separate audio and video sources and want to produce a single combined media file.

Common scenarios include:

  • Adding background music or narration to a silent video.
  • Replacing the original audio track of a video with a different audio source.
  • Combining externally sourced audio (e.g., voiceover) with video footage.

Example: You have a video recording without sound and a separate audio commentary file. Using this node, you can combine them into one video file with the commentary embedded.

Properties

Name Meaning
Video Input A valid video URL or the name of the input binary field containing the video file.
Audio Input A valid audio URL or the name of the input binary field containing the audio file.
Video Output Name The name of the output binary field where the combined video file will be stored. Default is "data".

Output

The node outputs a binary file in the specified output field containing the video merged with the provided audio track. The json output typically includes metadata about the processed file, but the main content is the combined video binary data.

If the input was binary data fields, the output binary field will contain the new video file with audio combined.

Dependencies

  • Requires an API key credential for accessing the underlying ffmpeg service.
  • The node depends on an external ffmpeg API or service configured via credentials in n8n.
  • No other external environment variables are explicitly required based on the static code.

Troubleshooting

  • Invalid Input URLs or Binary Fields: Ensure that the video and audio inputs are either valid URLs accessible by the service or correctly named binary fields in the workflow.
  • Missing or Incorrect Credentials: The node requires a valid API key credential for the ffmpeg service; missing or invalid credentials will cause authentication errors.
  • Unsupported Media Formats: If the input video or audio formats are not supported by the ffmpeg backend, the operation may fail.
  • Output Field Conflicts: Make sure the output binary field name does not conflict with existing fields to avoid overwriting important data.
