Locked First Frame with Strict Reference Fidelity
Grok Imagine video prompt by Lorraine Marie Varela · original post
A first-and-last-frame video prompt that treats an uploaded image as the sole authority for the entire sequence. It forbids any reinterpretation, redesign, or added elements, requiring the character's identity, proportions, materials, textures, lighting, props, posture, and environment to stay unchanged frame by frame.
the prompt
REFERENCE AUTHORITY (NON-NEGOTIABLE): The uploaded image is the locked starting frame and sole authority. This frame must be referenced frame by frame throughout the sequence. The character's identity, scale, proportions, materials, textures, lighting, props, posture, and environment do not change. No reinterpretation. No harmonization. No redesign. No new elements may be introduced at any point.
