# AI Video Enhance API
> AI video quality enhancement for improving clarity, resolution, and visual fidelity.
## Overview
`video-enhance` is an AI video enhancement endpoint for improving video clarity and output quality.
It supports standard or professional enhancement modes, multiple scene presets, selectable output resolution, and frame rate control.
## Query Task Status
After submitting a task, use the unified query endpoint to check progress and retrieve results:
Learn how to query task status and retrieve generation results
For production use, we recommend using the `callback_url` parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.
