Describe Motion Explicitly
Video models need temporal cues — describe what moves, how fast, and over what duration. "A cat jumping" is weaker than "A ginger cat leaps onto a windowsill, landing softly."

Describe the subject and action. Be specific — motion details anchor the temporal generation.
Aspect Ratio
16:9 for cinematic, 9:16 for mobile reels, 1:1 for social.

Video Diffusion Prompt Best Practices
Anchor the Camera
Static shots hold longer. Dolly zooms and FPV drone moves add energy but can reduce temporal consistency if overused.
Match Duration to Action
4s works for quick reveals; 10s suits slow, cinematic movements. Shorter clips often produce cleaner temporal coherence.
Aspect Ratio by Platform
16:9 for cinematic video, 9:16 for TikTok/Reels/Shorts, 1:1 for Instagram posts. Composition changes with frame shape.

Camera Kinematics & Temporal Consistency
Camera Kinematics
Dolly Zoom changes focal length while moving the camera — creating the iconic "Vertigo" effect. Pan and Tilt rotate around axes; Orbit circles the subject. Each kinematic affects how the model interprets motion over time.
Temporal Consistency
Video models generate frame-by-frame with learned motion priors. Fast action (High-Speed) risks morphing artifacts; Slow Motion improves per-frame fidelity but stretches generation time.
Model-Specific Tuning
Sora responds well to detailed natural language with camera direction. Runway likes concise shot descriptors. Luma benefits from lighting and mood emphasis. Adjust phrasing per model.
Duration & Frame Rate
Most models output 4–10 second clips at 24fps. Longer durations compound temporal drift — generate shorter segments and stitch them for extended sequences.
