# Request media asset analysis (deprecated)

Available in VPC

              Caution

              

This API is deprecated and is scheduled to be removed in January 2027. Use the new [Request media asset analysis](/docs/en/mi-request-index) API.

Analyze a media asset to create an index, which is the result of analysis. After media asset registration is complete, requesting an analysis will execute the analysis process. The detailed workflow is as follows:

![maiu-request-analysis_workflow](https://cdn.document360.io/da0368a0-4444-4862-a528-42f78876f9e6/Images/Documentation/maiu-request-analysis_workflow.png?sv=2026-02-06&spr=https&st=2026-11-14T05%3A22%3A19Z&se=2026-11-14T06%3A22%3A19Z&sr=c&sp=r&sig=4%2FGVfPlCLo8hIqvqVCOkZyF16CNJDzqQTcY2%2B%2FVScWk%3D)

## Request

This section describes the request format. The method and URI are as follows:

| Method | URI |
| --- | --- |
| POST | /api/v1/workspaces/{workspace_name}/projects/{project_id}/assets/{asset_id}/analyze |

### Request headers

For information about the headers common to all Media Intelligence APIs, see [Media Intelligence request headers](/docs/en/maiu-overview#%EC%9A%94%EC%B2%AD%ED%97%A4%EB%8D%94).

### Request path parameters

You can use the following path parameters with your request:

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `workspace_name` | String | Required | Workspace name |
| `project_id` | String | Required | Project ID - See [Get project list](/docs/en/maiu-list-projects). |
| `asset_id` | String | Required | Media asset ID - See [Get media asset list](/docs/en/mi-list-assets). |

### Request body

You can include the following data in the body of your request:

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `sceneRange` | String | Optional | (During video analysis) Length of automatically split scenes - `EXTRA_SHORT` \| `SHORT` \| `MEDIUM` (default) \| `LONG` - `EXTRA_SHORT`: Between 10-20 seconds - `SHORT`: Analyze detailed scenes in the video with second-by-second segmentation. - `MEDIUM`: Capture key changes while maintaining proper flow between scenes. - `LONG`: Maintain a natural flow by enhancing connectivity between scenes. - It can't be used at the same time with `minSceneDurationSec` and `maxSceneDurationSec`. |
| `minSceneDurationSec` | Integer | Optional | (During video analysis) Minimum scene length (second) - Allowed range: 10-30 - Default: 15 - It must be used in conjunction with `maxSceneDurationSec`. If entered on its own, it returns a 400 error. - It can't be used at the same time with `sceneRange`. |
| `maxSceneDurationSec` | Integer | Optional | (During video analysis) Maximum scene length (second) - Allowed range: 25-300 - Default: 120 - It must be used in conjunction with `minSceneDurationSec`. If entered on its own, it returns a 400 error. - It can't be used at the same time with `sceneRange`. |
| `analysisPersonCount` | Integer | Required | Number of people to detect when analyzing - 0-10 - When 0 is entered, people are not analyzed, which speeds up analysis. |
| `tagIdList` | Array | Optional | Tag of people to detect when analyzing - Length: 1-30 |
| `sourceLanguage` | enum | Optional | Language information of the original being analyzed - `KO` (default) \| `ENKO` \| `EN` \| `JA` \| `ZH-CN` \| `ZH-TW` - `KO`: Korean - `ENKO`: Korean + English - `EN`: English - `JA`: Japanese - `ZH-CN`: Chinese (Simplified) - `ZH-TW`: Chinese (Traditional) |
| `detectAudioEffects` | Boolean | Optional | (During video analysis) Audio effect detection - `true` \| `false` (default) - Detect "applause," "laughter," and "background music" items when enabled. |

              Note

              

`sceneRange` and `minSceneDurationSec`/`maxSceneDurationSec` can't be used at the same time. When customizing scene duration, be sure to specify both `minSceneDurationSec` and `maxSceneDurationSec`.

### Request example

The request example is as follows:

**Preset method**

```
curl --location --request POST 'https://mi.apigw.ntruss.com/api/v1/workspaces/my-workspace/projects/1234/assets/5678/analyze' \

--header 'Content-Type: application/json' \
--data '{
"minSceneDurationSec": 15,
"maxSceneDurationSec": 60,
"sourceLanguage": "KO",
"detectAudioEffects": false,
"analysisPersonCount": 3
}'
```

| Error code | Message | Description |
| --- | --- | --- |
| 400 | sceneRange and minSceneDurationSec/maxSceneDurationSec are mutually exclusive | `sceneRange` and custom range entered at the same time. |

| 400 | minSceneDurationSec must be less than or equal to maxSceneDurationSec | When `minSceneDurationSec` > `maxSceneDurationSec` |
| 400 | minSceneDurationSec out of range (10–30) | `minSceneDurationSec` exceeded the allowed range. |
| 400 | maxSceneDurationSec out of range (25–300) | `maxSceneDurationSec` exceeded the allowed range. |
