# Video Duration

This block retrieves the duration of video or audio files, useful for planning and conditional logic in media workflows.

## Media Duration

### What it is

Block to get the duration of a media file.

### How it works

The block uses MoviePy to load the media file and extract its duration property. It supports both video files (using VideoFileClip) and audio files (using AudioFileClip), determined by the `is_video` flag. The media can be provided as a URL, data URI, or local file path. The duration is returned in seconds as a floating-point number.

### Inputs

| Input     | Description                                           | Type       | Required |
| --------- | ----------------------------------------------------- | ---------- | -------- |
| media\_in | Media input (URL, data URI, or local path).           | str (file) | Yes      |
| is\_video | Whether the media is a video (True) or audio (False). | bool       | No       |

### Outputs

| Output   | Description                              | Type  |
| -------- | ---------------------------------------- | ----- |
| error    | Error message if the operation failed    | str   |
| duration | Duration of the media file (in seconds). | float |

### Possible use case

* Checking video length before processing to avoid timeout issues
* Calculating how many times to loop a video to reach a target duration
* Validating that uploaded content meets length requirements
* Building conditional workflows based on media duration

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://agpt.co/docs/integrations/block-integrations/duration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
