# Crun P Video Avatar API
> Generate talking-head videos from a single portrait image plus either a script or an audio clip. Upload a photo, give it words to say (or audio to lip-sync to), and get back a video of the person speaking.
## Overview
p-video-avatar is Pruna’s first avatar model. It’s optimized for speed and cost — the cheapest
avatar/lipsync option in this category — while still producing natural lip movements and facial expressions.
## 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.
