Overview
This node provides video processing capabilities using ffmpeg, specifically supporting an operation to extract audio from a video file ("Video To Audio"). It is useful when you want to convert video content into audio format for purposes such as podcast creation, transcription, or audio analysis. For example, you can input a video URL or binary video data and output an audio file with customized codec, bitrate, and channel settings.
Properties
| Name | Meaning |
|---|---|
| Video Input | A valid video URL or the name of the input binary field containing the video to process. |
| Audio Output Name | The name of the output binary field where the extracted audio file will be stored. |
| Video Processing Options | Collection of optional parameters: - Audio Codec (string): specify audio codec. - Audio Bitrate (number): set audio bitrate in kbps (default 128). - Audio Channels (number): number of audio channels (default 1). |
Output
The node outputs the extracted audio as binary data under the specified output binary field name. The json output contains metadata about the processed file, while the binary data holds the actual audio file extracted from the input video.
Dependencies
- Requires an API key credential for accessing the underlying ffmpeg service.
- Relies on ffmpeg functionality exposed via an external API or service configured in n8n.
- No additional environment variables are explicitly required based on the static code.
Troubleshooting
- Invalid Video Input: If the video input URL or binary field is incorrect or inaccessible, the node will fail to retrieve or process the video. Ensure the input is valid and accessible.
- Unsupported Audio Codec: Specifying an unsupported audio codec may cause errors. Use common codecs supported by ffmpeg.
- Incorrect Binary Field Names: Make sure the input and output binary field names correspond correctly to your workflow's data structure.
- API Authentication Errors: Verify that the API key credential is properly configured and has necessary permissions.
