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:
- Extracting a specific scene from a recorded video.
- Trimming silence or noise from an audio recording.
- Creating short promotional clips from longer videos.
For example, if you have a 10-minute video but only want the segment from 2:00 to 3:30, this node can cut that portion and output it as a new media file.
Properties
| Name | Meaning |
|---|---|
| Video or Audio Input | A valid URL pointing to the video/audio file or the name of the input binary field containing the media to process. |
| Cut Start Time (in Sec) | The starting point (in seconds) from which to begin cutting the media. Must be zero or positive. |
| Cut End Time (in Sec) | The ending point (in seconds) at which to stop cutting the media. Must be zero or positive. |
| Video or Audio Output Name | The name of the output binary field where the resulting 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 user (default is "data"). The json output contains metadata about the processed item, while the binary data holds the actual media file segment corresponding to the cut range.
If the input was a video, the output binary data represents the trimmed video clip; if audio, the trimmed audio segment.
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.
- Proper configuration of the API authentication token or credentials is necessary for the node to function.
Troubleshooting
- Invalid Input URL or Binary Field: Ensure the input media URL is accessible or the binary field name is correct and contains valid media data.
- Start or End Times Out of Range: The start and end times must be within the duration of the input media. Setting them outside the valid range may cause errors or empty outputs.
- Missing or Invalid Credentials: The node requires proper API credentials to communicate with the ffmpeg service. Verify that the credentials are set up correctly in n8n.
- Output Binary Field Conflicts: Make sure the output binary field name does not conflict with existing fields to avoid overwriting important data.
Common error messages might indicate issues like "Invalid media input," "Authentication failed," or "Cut times out of bounds." Resolving these typically involves verifying inputs, credentials, and parameter values.
