  "prompt": "Smooth tracking shot around a sleek smartphone on a white pedestal, soft studio lighting, product photography style, reflections on surface, 4K, shallow depth of field"
}'

Nature Documentary

Model-Specific Tips

Google Veo

• Excels at realistic, cinematic content
• Supports audio generation (Veo 3+)
• Best with detailed, professional prompts
• Frame interpolation available in 3.1

Seedance

• Strong at dance and human motion
• First-frame control available
• Good for consistent character motion
• Works well with reference images

Wan 2.5

• Best for image-to-video
• Animates still images naturally
• Good motion prediction
• Works with any image style

Grok

• Good general-purpose video
• Configurable duration (5-10s)
• Creative interpretations
• Works well with abstract concepts

Workflow: Iterative Prompting

# 1. Start with basic prompt
infsh app run google/veo-3-1-fast --input '{
  "prompt": "A woman walking through a forest"
}'

# 2. Add specificity
infsh app run google/veo-3-1-fast --input '{
  "prompt": "Medium tracking shot of a woman in a red dress walking through an autumn forest"
}'

# 3. Add style and technical details
infsh app run google/veo-3-1-fast --input '{
  "prompt": "Cinematic medium tracking shot of a woman in a flowing red dress walking through an autumn forest, golden hour sunlight filtering through leaves, shallow depth of field, film grain, 4K"
}'
