Use the FIRST FRAME as the exact visual starting point and the LAST FRAME as the exact visual ending point. Preserve both keyframes as faithfully as possible. The first frame must remain visually identical in composition, subject placement, camera angle, facial structure, clothing, dental chair, medical equipment, lighting layout and background details. The last frame must also remain visually faithful to the provided final frame. Generate ONLY the transformation between these two fixed keyframes. Create a TRUE CONTINUOUS MORPHING TRANSITION from the first frame into the last frame. Do NOT use a dissolve, crossfade, opacity blend or double exposure. The scene must physically transform frame by frame. Every major visual element in the first frame should continuously evolve into its corresponding element in the last frame: * the historical dentist physically morphs into the modern dentist while preserving spatial position and body continuity; * the patient continuously transforms into the final patient without disappearing or being replaced; * the dental chair reshapes structurally into the modern chair; * old dental instruments and equipment mechanically transform into their modern counterparts; * furniture, walls and background objects smoothly reconstruct into the final modern environment; * monochrome textures gradually evolve into realistic modern materials and colors; * clothing changes through continuous fabric transformation, not through fading; * facial features evolve gradually and coherently without sudden identity changes. The transition must contain clear intermediate hybrid forms. At every moment there should be ONE coherent scene, not two scenes layered together. Each object must have continuous geometry from beginning to end. Use smooth semantic morphing, optical-flow-like deformation, shape interpolation, texture transformation and physical reconstruction. Maintain exact camera lock. No camera movement. No zoom. No pan. No reframing. No change in perspective. Maintain the original spatial layout throughout the entire transition. IMPORTANT: Do not alter the first frame. Do not redesign the first frame. Do not simplify historical details. Do not invent new objects at the beginning. Do not replace the subjects with different people before the transformation begins. The first 10–15% of the video should stay extremely close to the FIRST FRAME before the visible morphing begins. The final 10–15% should settle cleanly into the LAST FRAME and remain stable. At no point may two independent images be alpha-blended together. No crossfade. No dissolve. No transparency. No ghosting. No double exposure. No overlapping duplicate faces or bodies. No sudden cuts. No scene replacement. The transformation must happen through geometry deformation, object reshaping, material evolution and semantic reconstruction only. One continuous cinematic metamorphosis from the exact first frame to the exact last frame. Photorealistic. Temporally coherent. Natural anatomy. Stable identities. High detail.
