Technologická architektúra

Diffusion Transformer Framework

# Koncepčná architektúra Sora
class SoraArchitecture:
    def __init__(self):
        self.model_type = "Diffusion Transformer"
        self.representation = "spacetime_patches"
        self.flexibility = {
            "resolutions": ["480p", "720p", "1080p", "4K"],
            "aspect_ratios": ["1:1", "16:9", "9:16", "4:3"],
            "durations": ["1s", "5s", "10s", "20s", "60s+"],
            "frame_rates": ["24fps", "30fps", "60fps"]
        }

    def generate_video(self, prompt, reference_image=None):
        # Spacetime patch tokenization
        patches = self.create_spacetime_patches(prompt, reference_image)

        # Diffusion process
        video = self.diffusion_transformer(patches)

        return self.post_process(video)

Best Practices a Optimization

Prompt Engineering

Effective prompting strategies

Prompt optimization:
  Specificity: "Detailed scene descriptions work better"
  Visual elements: "Describe lighting, camera angles, mood"
  Motion description: "Specify movement patterns and speed"
  Style references: "Mention cinematography styles"

Example effective prompts:
  - "Close-up shot of raindrops on a window during a thunderstorm,
     dramatic lighting, slow motion, cinematic quality"
  - "Wide angle view of a bustling Tokyo street at night,
     neon signs reflecting on wet pavement, steady camera movement"

Common mistakes to avoid

Avoid these patterns:
  - Overly complex scenes with many elements
  - Ambiguous motion descriptions
  - Conflicting visual styles in one prompt
  - Extremely fast or chaotic movement requests

Workflow Integration

Production pipeline

Recommended workflow:
  1. Concept development: "Text prompt refinement"
  2. Reference gathering: "Visual inspiration and style guides"
  3. Generation testing: "Multiple variations and iterations"
  4. Post-processing: "Editing and enhancement"
  5. Quality review: "Technical and creative evaluation"
