How is AI video generation different from image generation?
AI video generation is more complex, expensive, and limited than image generation.
Key differences:
| Aspect | Image Generation | Video Generation |
|---|---|---|
| Duration | N/A | 5-20 seconds typical |
| Control | High | Medium |
| Cost | Low | High |
| Speed | Fast | Slow |
| Quality | Excellent | Good to excellent |
| Consistency | Good | Challenging |
Challenges unique to video:
- Temporal consistency (keeping things stable across frames)
- Motion coherence (natural movement)
- Character consistency throughout
- Higher computational requirements
- More expensive per generation
Current limitations:
- Short clip lengths (5-20 seconds max)
- Character morphing/distortion
- Physics inconsistencies
- Limited precise control
- Long generation times
When to use AI video:
- Concept visualization
- Motion backgrounds
- Short-form social content
- Creative exploration
- Supplementing real footage
For longer videos, you’ll typically generate multiple short clips and edit them together with transitions.
