Made With Runway Gen-4.5
GOOD FOR
Where it Excels
Cinematic Realism
Generates high fidelity, polished, and detailed footage suitable for professional marketing and film making.
Consistency
Excellent at maintaining consistency over time, meaning textures, hair, and lighting do not randomly flash or change.
Precise Control
Offers strong adherence to prompts and allows for detailed camera control.
Complex Scenes
Good at managing multiple moving elements in a scene without losing stability.
TRY TO AVOID
Not Ideal For
Native audio output
Generates silent video only. Audio must be added externally using a separate model or audio tool.
Causal Reasoning
May struggle with cause and effect, such as showing the effect before the cause happens.
Animated or Stylized Content
Can sometimes lack the artistic depth or specific styling required for animated, non photorealistic illustrations.
Causal reasoning edge cases
Effects can sometimes precede causes, objects may vanish when occluded, and actions disproportionately succeed.
