Overview
This node provides video processing capabilities using ffmpeg, specifically supporting an operation to combine audio with a video. The "Combine Audio To Video" operation allows users to merge an audio track into an existing video file, producing a new video output that includes the added audio.
Common scenarios for this node include:
- Adding background music or narration to silent videos.
- Replacing or overlaying audio tracks in video content.
- Combining separate audio and video files into a single media file for easier distribution or playback.
For example, a user might have a video recording without sound and a separate audio commentary track; this node can merge them into one video file with synchronized audio.
Properties
| Name | Meaning |
|---|---|
| Video Input | A valid video URL or the name of the input binary field containing the video file to process. |
| Audio Input | A valid audio URL or the name of the input binary field containing the audio file to add. |
| Video Output Name | The name of the output binary field where the resulting combined video file will be stored. |
Output
The node outputs a binary file representing the video with the newly combined audio track. This output is stored in the specified output binary field (default name: data). The JSON output typically contains metadata about the processed item, but the main result is the binary video data ready for further use or export.
Dependencies
- Requires an API key credential for accessing the underlying ffmpeg service.
- Depends on ffmpeg functionality exposed via an external API or service configured within n8n.
- The node expects valid URLs or binary fields containing media files as inputs.
Troubleshooting
- Invalid Input URLs or Binary Fields: Ensure that the provided video and audio inputs are accessible and correctly referenced. Invalid URLs or missing binary data will cause processing failures.
- Unsupported Media Formats: The node relies on ffmpeg's supported formats. Using unsupported video or audio codecs may lead to errors.
- API Authentication Errors: Verify that the API key credential is correctly set up and has necessary permissions.
- Output Field Conflicts: Make sure the output binary field name does not conflict with existing fields to avoid overwriting important data.
