# Trim video - Workflow node | Docs - nodulz

Source: https://nodulz.com/docs/nodes/trim_video

Language: en

Extract a video segment with FFmpeg.

## 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 : `trim_video`. 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](/docs/credentials) 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` | `""` | - |
| `start` | `number` | `0` | -; ≥ 0, ≤ 86400 |
| `duration` | `number` | `5` | -; ≥ 0, ≤ 86400, > 0 |

## Initial configuration

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

```json
{
  "input": "",
  "start": 0,
  "duration": 5
}
```

## 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.
