Sora 2.0 Physics Mastery: The 5-Step Prompt Formula to Eliminate Continuity Errors

Solve the problem of disappearing or deforming objects in Sora 2.0 videos. Learn the 'Physics Anchoring' Formula to perfectly fix character and object consistency, maximizing the quality of commercial video production.

Introduction: Why Does Sora's Coffee Cup Keep Changing Shape?

OpenAI Sora 2.0 boasts astonishing realism, yet users still face Physical Continuity Errors: objects disappearing, or a character's clothing changing between frames. This occurs because Sora, as a generative model, has to 'guess' the next shot based on the previous one. For commercial video creators aiming for high quality, you must eliminate this margin of guesswork by forcing 'Physics Rules' through your prompt. This guide provides five 'Physics Anchoring' Formulas to achieve near-100% elimination of Sora’s continuity flaws, elevating your AI content to the highest professional standard.

1. Anchoring Temporal Consistency: The 'Timeline Anchor' Formula

You must explicitly inform Sora about the video's length and timeline flow to lock the lifespan of objects and the sequence of actions.

Specifying 'Action Beats' and Time Constraints

Include clear numerical constraints or sequential steps in the prompt, such as '3-step process' or 'for 5 seconds'. This prevents the model from skipping intermediate steps or scrambling the order.

• Weak Example: "A man walks, eats an apple, then puts on a coat." (Ambiguous sequence and time)

• Strong Example (The Anchor): "A man performs a 3-step sequence: First 2 seconds: he walks into the frame. Next 5 seconds: he slowly eats a red apple, leaving the core in his hand. Final 3 seconds: he puts on a navy coat, the apple core remains visible on the table."

Designating 'Immutable Objects'

Emphasize core props within the scene that must not change or disappear to heighten the model's focus. This is paramount for maintaining consistency.

• Example: "A woman is intensely focused on her laptop. The silver wristwatch on her left wrist (Immutable Object) must remain perfectly consistent in every frame."

2. Anchoring Spatial Consistency: The 'Coordinate Framing' Formula

Sora simulates 3D space, but object placement still relies on the prompt. You must lock spatial coordinates to reduce visual chaos.

Fixing 'Frame Position' and 'Angle'

The greater the camera movement, the higher the chance of object placement error. You must bind the camera movement to the subject's position within the frame.

Consistency Goal	Prompt Keywords Example	Rationale
Fixing Subject Position	"Subject remains Center Frame throughout a Slow Dolly Shot."	Forces the subject to not drift out of the center
Fixing Background Props	"A detailed, worn-out leather journal is placed on the table, always visible in the foreground left."	Prevents the prop from suddenly vanishing or shifting location

3. Anchoring Subject Consistency: The 'Detail Locking' Formula

To prevent the subject's appearance or attire from morphing (common in longer clips), you must set specific 'locking mechanisms'.

Locking via 'Beat-Unit Detail Specification'

Describing a subject's appearance shouldn't be a one-time instruction. You must repeat key details within action beats to remind the model.

• Locking Example: "A man with a single, distinctive scar under his left eye (Lock 1) wears a deep emerald green velvet jacket (Lock 2)."

• Action Extension: "He turns to look at the sunset, the scar and the emerald jacket remain perfectly consistent."

Controlling Non-Physical Elements

Expressions and emotions are easily distorted, so substitute them with physical actions for better consistency.

• Weak Example (Prone to Deformation): "The man has a sad expression."

• Strong Example (Physical Control): "The man slowly lowers his gaze (Physical Action) while maintaining a neutral mouth expression (Physical Lock)."

4. Anchoring Camera Consistency: The 'Lens Signature' Formula

Maintaining aesthetic coherence across scenes is essential. Embed the camera and lens settings like a 'signature' on the entire prompt.

Enforcing a 'Cinematic Signature'

Place these instructions at the very end of your prompt to unify the visual language of the entire video.

• Lens & Format: "Shot on an ARRI Alexa 65, using 80mm Prime Lens, Cinematic 2.39:1 aspect ratio."

• Filmic Look: "Kodak Vision3 500T film emulation, subtle film grain, slight halation on highlights."

• Consistency Declaration: "All visual parameters including depth of field and color temperature must remain perfectly fixed between shots."

5. Anchoring Motion Consistency: The 'Motion Vector' Formula

Unstable camera movement is a primary cause of object distortion. You must constrain the speed and direction of the movement itself.

Preventing Distortion via 'Speed Vector' Specification

Specify a clear speed for the camera's motion to prevent the subject's form or background from 'smearing' excessively.

• Prompt Example: "Camera moves extremely slow and steady (speed limit) on a Dolly Track (fixed axis), tracking the subject's movement from the side. ZERO Camera Shake."

Aligning Motion Between Sequential Clips

When stitching multiple clips, explicitly align the movement of the last shot with the starting movement of the next shot in the prompt.

• Example: "This clip must end with the camera panning left at a medium pace to reveal the next scene, matching the motion vector for the subsequent shot."

Frequently Asked Questions (FAQ)

1. Why are 'Physical Consistency Errors' fatal for commercial video?

Answer: Commercial content (ads, films, dramas) must maintain viewer immersion and accurately showcase product details. Errors like a changing cup shape or a vanishing ring create the 'Uncanny Valley' effect, immediately reducing the video's credibility and professionalism, negatively impacting brand value.

2. Doesn't a very long prompt actually lead to poorer results?

Answer: The length of the prompt is not the problem; ambiguity or conflicting instructions are. The Physics Anchoring formulas eliminate unnecessary adjectives and focus on clearly listing control parameters (technical terms), which, while increasing length, enhances the model's focus and control.

3. How do I prevent the 'skin melting' effect during extreme close-ups?

Answer: Stop the movement during the close-up. Enforce "Extreme Close-up, Steady Camera, Zero Motion" to fix the facial texture and form. Focus on using 'Shallow DOF' and 'Soft Light' to enhance realism instead of relying on complex emotional descriptions.
