The four criteria
- Realism
- Believable light, materials, anatomy and physics. No artifacts.
- Motion
- Smooth, consistent movement from frame to frame, controlled camera moves.
- Prompt adherence
- Does the model do what was asked: subject, action, framing, on-screen text?
- Art direction
- Aesthetic quality and the ability to hold a given style.
The overall score is the average of the four criteria (three for images, where motion does not apply), rounded to one decimal. A score marked “provisional” will be confirmed once the full test is complete.
Pricing
