# VideoTrim - ComfyUI Built-in Node Documentation

> This node cuts a video to a chosen time window by setting a start time and a duration.

This node cuts a video to a chosen time window by setting a start time and a duration. It also offers a strict mode that raises an error when the requested duration cannot be achieved.

## Inputs

| Parameter         | Description                                                                                                                                                                                                                                          | Data Type   | Required | Range                                                       |
| ----------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------- | -------- | ----------------------------------------------------------- |
| `video`           | The video to trim.                                                                                                                                                                                                                                   | VIDEO       | Yes      | —                                                           |
| `trim`            | Trim window using start/end frames. The window is converted into a start time (in seconds from the beginning of the video) and a duration (in seconds). When both the start time and the duration are 0, the video is returned without any trimming. | VIDEO\_EDIT | Yes      | start\_time: >= 0, default 0<br />duration: >= 0, default 0 |
| `strict_duration` | If True, when the specified duration is not possible, an error will be raised. (default: False)                                                                                                                                                      | BOOLEAN     | No       | true<br />false                                             |

Note: The trim duration must be >= 0; negative values raise an error. The requested trim window must fit inside the source video. If the trim cannot be applied, an error is raised that reports the source duration, start time, and target duration.
