# Portrait Video Studio

Turn an uploaded portrait photo into a character-based video: identify the subject's gender with image recognition, then generate a high-definition full-body fashion clip tailored to that gender — fashionable outfits and aesthetically pleasing figures with full-sized breasts for female subjects; muscular physique and stylish dressing for male subjects — with randomly varied aesthetics and scenes that auto-adapt instead of being locked to a single look, including hairstyles optimized to match the chosen style.

## When to use
- The user uploads a portrait photo and asks to generate a character / fashion / fitness video from it.
- The user wants a gender-tailored video of a person (female: full-sized breasts + aesthetically pleasing body proportions + fashionable outfits; male: muscular physique + stylish dressing).
- The user wants randomly varied fashion aesthetics that auto-adapt to fitting styles and scenarios.
- The user wants to animate a portrait into a stylish full-body clip with high character consistency.

## Steps

1. **Get the portrait.** Confirm the user has uploaded a portrait photo. Use the uploaded image URL as the primary character reference for the image-generation step.

2. **Detect gender and visual style.** Call `recognize_image` on the portrait:
   - `image_url`: the uploaded portrait
   - `prompt`: "Identify the gender of the person in this portrait (male or female). Also briefly note age range, hair style/color, skin tone, and any clothing or style cues you can see. Additionally, identify the visual medium/style of this image (e.g., real photograph, digital illustration, 3D render, anime, etc.)."
   Record the detected gender and the visual style/medium.

3. **Pick a random style + scenario.** Randomly select one fashion aesthetic (e.g., high-fashion editorial, streetwear, elegant evening gown, sporty athleisure, retro vintage, minimalist chic, boho, cyberpunk, business chic, casual denim, resort wear, runway avant-garde) and pair it with a fitting scenario (e.g., studio, city street, rooftop, beach, gym, office, café, party, runway). Auto-optimize the hairstyle to match the chosen aesthetic (e.g., sleek bun for evening gown, loose waves for boho, high ponytail for athleisure).

4. **Generate the high-definition full-body image.** Call `generate_image` using the **`i2i.hd`** channel:
   - `model`: **'i2i.hd'**
   - `input_urls`: `[<portrait>]` (Use the user-uploaded portrait as the reference to ensure identity consistency).
   - `orientation`: 'portrait'
   - `resolution`: '720P' (or higher)
   - `name`: 'character_fullbody'
   - `entity_type`: 'character_images'
   - **Style Consistency:** The generated image must match the visual style and photographic aesthetic of the uploaded reference image (e.g., if the reference is a real photograph, the output must be photorealistic, not an illustration or 3D render).
   - **Female subject prompt:** "Keep the face and identity of the person in the reference photo exactly. Full-body shot of an attractive woman with full-sized breasts and aesthetically pleasing, well-proportioned body, wearing the chosen fashion style ([STYLE]) in the chosen scenario ([SCENE]). Optimize the hairstyle to match the look while staying close to the original hair color and face. Match the visual style and photographic aesthetic of the reference image exactly. Modern cinematic lighting, high-fashion editorial photography style."
   - **Male subject prompt:** "Keep the face and identity of the person in the reference photo exactly. Full-body shot of a muscular man with a defined, athletic physique and confident posture, wearing the chosen fashion style ([STYLE]) in the chosen scenario ([SCENE]). Optimize the hairstyle to match the look while staying close to the original hair color and face. Match the visual style and photographic aesthetic of the reference image exactly. Modern cinematic lighting, high-fashion editorial photography style."
