AI Video Generation: Create Videos with Sora, Runway, and Pika Labs

AI video generation has advanced rapidly, enabling creators to produce video content from text descriptions, images, or existing footage. This technology is transforming content creation, marketing, and entertainment.

What is AI Video Generation?

Input types:

• Text descriptions (text-to-video)
• Still images (image-to-video)
• Existing video (video-to-video)
• Audio (for lip sync)

Applications:

• Bring photos to life
• Animate artwork
• Create motion from illustrations
• Product animations

Tips:

• High-quality source images work best
• Simple, clear subjects animate better
• Consider what motion makes sense

Prompting for Video

Structure Your Prompts

Include:

• Subject: Who or what is in the video
• Action: What is happening
• Setting: Where it takes place
• Style: Visual treatment
• Camera: Movement and framing
• Mood: Atmosphere and feeling

Example Prompts

Cinematic: "Slow motion close-up of rain drops falling on green leaves, soft natural lighting, shallow depth of field, peaceful atmosphere"

Product: "Sleek smartphone rotating on a white pedestal, soft studio lighting, reflections visible on surface, professional product video"

Artistic: "Abstract flow of colorful paint in water, macro photography style, vibrant blues and golds, dreamy and ethereal"

Prompt Tips

Be specific: Instead of "a city", try "busy Tokyo intersection at night with neon signs reflecting on wet streets"

Describe motion: Include verbs and direction - "walking toward camera", "slowly panning right", "objects floating upward"

Set the mood: Add emotional descriptors - "mysterious", "joyful", "tense", "serene"

Frequently Asked Questions

How long can AI-generated videos be?

Currently, most AI video generators create clips of 4-10 seconds. Sora can generate up to 60 seconds. For longer content, you typically combine multiple generated clips with editing software. Longer generation capabilities are actively being developed.

Can I use AI-generated videos commercially?

Commercial use depends on the specific tool and subscription tier. Paid tiers of Runway, Pika Labs, and similar tools typically allow commercial use. Always check the terms of service for your specific use case, especially for advertising or products.
