Pruna AI P-Video Avatar API

Pruna AI P-Video Avatar

Pruna AI P-Video Avatar generates a talking or performing avatar video from a reference image and an audio clip, with optional prompt guidance for motion and expression. It is designed for character-driven video generation where the image defines the avatar and the audio drives the timing and delivery.

Why Choose This?

• Image + audio avatar generation Combine a reference image with an audio track to generate a video avatar performance.

• Prompt-guided motion control Use video_prompt to nudge expression, movement, or overall performance style.

• Simple output settings Choose resolution and seed without a heavy configuration workflow.

• Audio-driven timing Video length follows the uploaded audio duration, making it easier to generate synced outputs.

• Production-ready workflow Useful for avatar clips, talking portraits, character presentations, and short-form content generation.

Parameters

Parameter	Required	Description
image	Yes	Reference image used as the avatar source.
audio	Yes	Audio file used to drive the avatar video.
video_prompt	No	Optional prompt describing expression, motion, or overall video style. Keep it simple for better stability.
resolution	No	Output resolution: 720p or 1080p.
seed	No	Random seed for reproducibility. Use the same seed for more consistent results.

How to Use

1. Upload your image — provide the reference image you want to animate.
2. Upload your audio — use a clear audio clip to drive the avatar performance.
3. Add a simple video prompt (optional) — describe only the key motion or mood you want.
4. Choose resolution — use 720p for lower cost or 1080p for higher quality.
5. Set a seed (optional) — use a fixed seed for more reproducible outputs.
6. Submit — run the model and download the generated avatar video.

Example Prompt

Natural head movement, subtle facial expression, stable identity, clean speaking performance, realistic motion

Pricing

• Minimum billed duration is 5 seconds
• Maximum billed duration is 600 seconds

• 1080p costs 1.8× the 720p rate
• video_prompt and seed do not affect pricing

Best Use Cases

• Talking avatar videos — Generate speaking portraits from a single image and audio track.
• Character presentation clips — Create short performance-based videos for storytelling or demos.
• Social media avatar content — Produce short avatar-driven clips for lightweight content workflows.
• Narration-driven character scenes — Pair a static character image with voice content for expressive video output.
• Prototype virtual presenters — Quickly test avatar-based presentation ideas without full animation workflows.

Pro Tips

• Keep the audio reasonably short for better reliability and easier iteration.
• Use a clear, front-facing image for better avatar stability.
• Keep video_prompt simple and direct — overly detailed prompts are more likely to fail.
• Focus the prompt on a few essentials, such as natural motion, subtle expression, or stable identity.
• Start with 720p for testing, then switch to 1080p for final-quality outputs.
• Reuse the same seed when you want more consistent variations.

Notes

• Both image and audio are required.
• Very long audio is not recommended; shorter clips are easier to generate successfully.
• The model works best when video_prompt is simple rather than highly detailed.
• Billing uses the audio duration, with a minimum of 5 seconds and a cap of 600 seconds.
• save_audio is not exposed in the current input settings shown here.
