Extract video audio

Node catalog Transformations

On this page

Export the audio track as MP3 or WAV.

Usage and specifics

Supply video or audio sources and operation settings. Processing requires backend media tools. Check duration, format and MIME type; preserve the complete output for the next node.

Technical type : extract_video_audio. Runtime : nodulz.

Credentials and prerequisites

This node defines no dedicated external credential. Remote sources or execution targets may still need their own access credentials.

See the credentials guide if a remote source or execution target requires access.

Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

Parameter	Type	Default	Values / limits
`input`	`string`	`""`	-
`format`	`enum`	`"mp3"`	`mp3`, `wav`

Configuration help

Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

json

{
  "input": "",
  "format": "mp3"
}

Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
