- Official-source policy: paraphrase BytePlus or paper material and cite the original source.
Prompt reuse checklist
- Name the exact input type: text, image, audio, video, first frame, or final frame.
- State what each reference controls so the model does not blend competing instructions.
- Use one camera move, one main action, and one final-frame payoff.
- Test the smallest version in HolyCrab before expanding the shot.

Example prompt

Common failure modes
The final frame is not specific; The motion between frames is too complex; The product identity changes
