Quick Start
Requires inference.sh CLI (belt). Install instructions
belt login
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:
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"
}'
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 '{

When both audio and voice_script are provided, audio takes priority.
1080p with Custom Style

"voice_script": "This is exciting news for our community!",
"voice": "Aoede (Female)",
