Pruna P-Video-Avatar

Generate talking head avatar videos from a single portrait image via inference.sh CLI.

P-Video-Avatar is the fastest and most cost-effective avatar video model available. Quality on par with Veo 3.0, 18x faster and 6x cheaper than alternatives like Fabric, OmniHuman, and HeyGen.

Quick Start

Requires inference.sh CLI (belt ). Install instructions

belt login

Generate avatar from portrait + text script

belt app run pruna/p-video-avatar --input '{ "image": "https://portrait.jpg", "voice_script": "Hello, welcome to our product demo!", "voice": "Zephyr (Female)" }'

Full Workflow: Generate Portrait + Avatar Video

Use Pruna P-Image to generate the portrait, then P-Video-Avatar to animate it:

1. Generate a portrait image with P-Image

belt app run pruna/p-image --input '{ "prompt": "professional headshot portrait of a young woman, neutral background, looking at camera, studio lighting, photorealistic", "aspect_ratio": "9:16" }'

2. Use the generated image URL to create the avatar video

belt app run pruna/p-video-avatar --input '{ "image": "<image-url-from-step-1>", "voice_script": "Hi there! Let me walk you through our latest features.", "voice": "Zephyr (Female)", "resolution": "720p" }'

Examples

Text Script with Voice Selection

belt app run pruna/p-video-avatar --input '{ "image": "https://portrait.jpg", "voice_script": "Welcome to our product walkthrough. Today I will show you three key features.", "voice": "Puck (Male)", "voice_language": "English (US)", "resolution": "720p" }'

Audio-Driven Avatar

Provide your own audio file instead of using built-in TTS:

belt app run pruna/p-video-avatar --input '{ "image": "https://portrait.jpg", "audio": "https://speech.mp3" }'

When both audio and voice_script are provided, audio takes priority.

1080p with Custom Style

belt app run pruna/p-video-avatar --input '{ "image": "https://portrait.jpg", "voice_script": "This is exciting news for our community!", "voice": "Aoede (Female)", "voice_prompt": "Enthusiastic and energetic tone, slightly faster pace", "video_prompt": "The person is presenting on stage with dramatic lighting", "resolution": "1080p" }'

Multilingual Content

Spanish

belt app run pruna/p-video-avatar --input '{ "image": "https://portrait.jpg", "voice_script": "Bienvenidos a nuestra demostración de producto.", "voice": "Kore (Female)", "voice_language": "Spanish" }'

Japanese

belt app run pruna/p-video-avatar --input '{ "image": "https://portrait.jpg", "voice_script": "こんにちは、製品デモへようこそ。", "voice": "Leda (Female)", "voice_language": "Japanese" }'
