ffmpeg Node

n8n Node for some Ffmpeg functionality

Actions11

Overview

This node provides video and audio processing capabilities using ffmpeg. Specifically, the "Cut Video/Audio" operation allows users to trim a segment from a given video or audio file by specifying start and end times in seconds. This is useful for extracting highlights, removing unwanted sections, or creating clips from longer media files.

Common scenarios include:

  • Creating short promotional clips from longer videos.
  • Extracting specific audio segments from podcasts or music tracks.
  • Removing intros/outros from recorded videos.

For example, a user can input a full-length video URL or binary data, specify start time as 30 seconds and end time as 90 seconds, and get a trimmed video containing only that 1-minute segment.

Properties

Name Meaning
Video or Audio Input A valid video or audio URL, or the name of the input binary field containing the media file.
Cut Start Time (in Sec) The starting point (in seconds) from which to begin cutting the media. Must be ≥ 0.
Cut End Time (in Sec) The ending point (in seconds) at which to stop cutting the media. Must be ≥ 0 and > start time.
Video or Audio Output Name The name of the output binary field where the trimmed media file will be stored.

Output

The node outputs the trimmed video or audio segment in a binary field named as specified by the "Video or Audio Output Name" property (default is "data"). The output contains the cut media file ready for further use or download.

The json output field typically includes metadata about the processed item, but the main content is provided as binary data representing the trimmed media.

Dependencies

  • Requires an API key credential for accessing the underlying ffmpeg service.
  • The node depends on ffmpeg functionality exposed via an external API or service configured within n8n.
  • No additional environment variables are explicitly required beyond the API authentication setup.

Troubleshooting

  • Invalid Input: If the input URL or binary field does not contain a valid video/audio file, the node may fail. Ensure the input is correct and accessible.
  • Start/End Time Errors: Setting the start time greater than or equal to the end time will cause errors. Verify that start < end and both are non-negative.
  • API Authentication Issues: Missing or invalid API credentials will prevent the node from executing. Confirm that the API key is correctly configured.
  • Unsupported Formats: Some media formats might not be supported by the underlying ffmpeg service, leading to processing failures.
  • Timeouts or Large Files: Processing very large files or slow network connections may cause timeouts. Consider pre-processing or splitting large inputs.
