Add an audio track to a video file via public URLs, with controls for muting original audio, volume adjustment, trimming, and webhook-based completion tracking.
Inputs

- url (required) — The public and downloadable URL of the video file
- mute — Whether to mute the original video audio
- audio_url — The public and downloadable URL of the audio file
- volume — Set audio volume from 0 to 100. 100 is the original volume and 0 is silent.
- trim — Whether to trim the audio to match video length (if longer)
- wait — If enabled, the node pauses the workflow and checks the server until the video generation is finished, then returns the full video object. If disabled, only the ID and creation timestamp are returned.

Output shape
The video object containing the ID and URL, or only the ID and creation timestamp if wait is disabled.
