AI Video Generator

Generate professional AI videos from text prompts using multiple providers.

Supported Providers

Usage

Basic Video Generation

from skills.ai_video_generator import VideoGenerator

gen = VideoGenerator(provider="runway")

# Simple prompt
video = gen.create(
    prompt="A cat walking in the rain at night, cinematic",
    duration=5,
    resolution="1080p"
)

# With scene planning
video = gen.create_from_script(
    script="""
    Scene 1: Wide shot of city skyline at sunset
    Scene 2: Close-up of person typing on laptop
    Scene 3: Product reveal with dramatic lighting
    """,
    style="cinematic"
)

Batch Processing

# Generate multiple videos
prompts = [
    "Product showcase: smartphone floating in space",
    "Tutorial: How to use the app",
    "Social media: 15-second promo clip"
]

videos = gen.batch_create(prompts, output_dir="./videos/")

Scene Planning

The skill automatically:

1. Analyzes prompt for key elements
2. Plans camera movements
3. Suggests transitions
4. Optimizes for target platform

Output Formats

• MP4 — Standard video
• GIF — Animated preview
• WEBP — Animated thumbnail
• Frames — Individual PNG frames

Examples

Product Video

prompt: "Modern smartphone floating in zero gravity, 
        rotating slowly, dramatic lighting, 
        dark background with subtle particles"

Social Media Clip

prompt: "Quick montage of app features, 
        fast cuts, upbeat music vibe, 
        colorful gradients, 9:16 vertical"

Tutorial Video

prompt: "Screen recording style, 
        cursor clicking through UI, 
        text annotations appearing, 
        clean minimal design"

Pitfalls

1. API Limits — Each provider has rate limits, use batch mode for multiple videos
2. Duration Limits — Most providers limit to 4-10 seconds per generation
3. Cost — Video generation can be expensive, preview with low-res first
4. Aspect Ratio — Specify aspect ratio in prompt for consistent results
