# Generate AI scene analysis

POST https://api.fastpix.com/v1/ai/{mediaId}/scene-analysis

This endpoint analyzes an existing media and divides it into distinct visual scenes. Each scene includes start and end timestamps with an AI-generated description, making it easier to understand, search, and navigate the video's visual content.

#### How it works

1. Send a `POST` request to this endpoint, replacing `<mediaId>` with the ID of the media for which you want to generate scene analysis.
2. The response confirms that the request was successful and returns the ID of the media. The job starts immediately after a successful request.
3. You can use the [video.media.ai.scene\_analysis.ready](https://fastpix.com/docs/webhooks/in-video-ai-events#videomediaaiscene_analysisready) webhook event to track and notify the status.
4. After the webhook event is received, you can use the [Get scene analysis](https://fastpix.com/docs/in-video-ai-api/scene-analysis/get-media-scene-analysis) endpoint to retrieve the generated scene analysis.

**Use case**: Use this feature to generate visual scene analysis for media that has already been uploaded, without requiring the user to upload it again.
