ffmpeg Node

n8n Node for some Ffmpeg functionality

Actions11

Overview

This node provides video transcoding functionality using ffmpeg. It allows users to convert input videos into different formats by specifying the desired video codec and various transcoding options such as bitrate, frame rate, and resolution. This is useful for scenarios where video files need to be optimized for different devices, platforms, or bandwidth constraints.

Practical examples include:

  • Converting a raw video file into an MP4 format with H.264 codec for web streaming.
  • Reducing video resolution and bitrate to create smaller files suitable for mobile viewing.
  • Changing the frame rate of a video to match broadcast standards.

Properties

Name Meaning
Video Input A valid video URL or the name of the input binary field containing the video to transcode.
Video Output Name The name of the output binary field where the transcoded video file will be stored.
Video Codec The codec to use for transcoding the video (e.g., h264, hevc).
Transcoding Options Collection of optional parameters:
- Video Bitrate: target bitrate in kbps (default 480)
- Fram Rate: frames per second (default 480)
- Resolution: output video resolution (default "640x480")

Output

The node outputs the transcoded video file in a binary field named according to the "Video Output Name" property. The json output contains metadata about the operation result, but the main content is the binary video data ready for further processing or saving.

Dependencies

  • Requires an API key credential for accessing the underlying ffmpeg service.
  • The node depends on an external ffmpeg-based service or API that performs the actual transcoding.
  • No additional environment variables are explicitly required based on the static code analysis.

Troubleshooting

  • Invalid Video Input: If the input video URL or binary field name is incorrect or inaccessible, the node may fail to fetch the video. Ensure the input is valid and accessible.
  • Unsupported Codec: Specifying an unsupported video codec can cause errors. Verify that the codec is supported by the underlying ffmpeg service.
  • Incorrect Transcoding Options: Providing invalid values for bitrate, frame rate, or resolution might lead to transcoding failures. Use sensible numeric values and standard resolution formats.
  • API Authentication Errors: Missing or invalid API credentials will prevent the node from connecting to the transcoding service. Confirm that the API key is correctly configured in n8n credentials.
