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 }'
