Performance Comparison
Visual Fidelity and Physics Simulation
Veo 3.1 leads in physical realism and nuanced visual elements like lighting, reflections, and material textures.
Prompt Adherence
Sora 2 remains ahead in following user prompts exactly. Veo 3.1 sometimes prioritizes visual impact over prompt precision.
Generation Speed
- Sora 2: Generally faster for standard-length videos.
- Veo 3.1: Slightly slower in Pro mode due to intensive rendering.
- Runway Gen-3: Balanced speed and quality.
Practical Use Cases
- Veo 3.1: High-end commercials, cinematic sequences.
- Sora 2: Instructional, social media content on a budget.
- Runway Gen-3: Versatile mid-range production needs.
