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 publishing or sharing.
For example, you might have a recorded video 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. |
| Audio Input | A valid audio URL or the name of the input binary field containing the audio file. |
| 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 containing the video with the newly combined audio track. This output is accessible via the specified output binary field name (default is "data"). The json output typically contains metadata about the processed file or confirmation of successful processing, but the main result is the binary video data with audio embedded.
Dependencies
- Requires an API key credential for accessing the ffmpeg service.
- Depends on the external ffmpeg processing backend exposed via an API.
- 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 either valid URLs accessible by the service or correctly named binary fields containing the media data.
- Unsupported Media Formats: The ffmpeg backend may not support certain video or audio formats. Verify compatibility before processing.
- API Authentication Errors: Make sure the API key credential is correctly configured and has sufficient permissions.
- Output Field Conflicts: If the output binary field name conflicts with existing fields, rename it to avoid overwriting important data.
