### Motion requirements

The video should contain normal-speed realistic motion.

Required:
- natural movement speed;
- realistic physical interactions.

Strictly avoid:
- slow motion;
- cinematic slow-motion effects;
- time lapse;
- fast-forward;
- exaggerated motion;
- unrealistic physics.

### Occlusion requirement

Include realistic but limited interactions.

Allowed:
- brief partial occlusion;
- subjects passing close to each other;
- temporary overlap.

Avoid:
