時代ごとに
・服装
・街並み
・背景
などを変化させています。
テロップもGemini Omni Flashでつけました。
完璧ではありませんが、ベース動画を活かしたまま、ここまで自然に時代変化できるのはかなり面白いですね😳

-------------------------------------------------------
**Please edit based on the uploaded video.**
Create a 10-second hyper-realistic cinematic video of a Japanese woman running continuously, where her outfit, hairstyle, AND background all transform together through 10 different eras of Japan.
**CHARACTER LOCK:**
The uploaded reference video defines this character permanently. Analyze the reference video carefully and extract the character's exact face, hair color, skin tone, body shape, age, height, and all physical features. These are frozen and identical in every single frame. Only the costume, hairstyle, and background change per era. Identity must never drift. This is non-negotiable.
**REFERENCE VIDEO USAGE:**
Extract from the reference video:
- Exact facial structure, features, and expression style
- Natural skin tone and texture
- Body proportions and height
- Natural hair color and base texture
- Running motion, posture, stride length, and gait rhythm
Match her natural running style exactly throughout all 10 scenes.

**BACKGROUND CHANGE — CRITICAL INSTRUCTION:**
**The background MUST change completely and dramatically on every single cut.**
Every scene must have a visually distinct, fully rendered, historically accurate environment.
The background is NOT a blur, NOT a void, NOT a neutral studio.
Each background must look like a real physical location from that specific era.
Ancient and medieval era backgrounds must feel especially immersive — heavy architecture, raw materials, dramatic lighting, period-accurate props and atmosphere.
If the background does not change dramatically between scenes, the output is considered failed.
**Treat the background transformation as equally important as the costume transformation.**
---
**LENS & FRAMING:**
Full-body side tracking shot — head to toe always in frame.
Slight low-angle for dynamism.
Shallow depth of field — character sharp, background clearly visible and recognizable.
Smooth lateral tracking motion following the run.
Background must fill the entire frame behind the character — no empty space, no fog replacing architecture.
---
**CAPTION FORMAT:**
2-line floating caption at bottom center of every scene.
Line 1: Era name (Japanese / English)
Line 2: Time period
Clean elegant font, warm white, dark drop shadow.
Never overlap outfit, shoes, or background landmarks.
Always exactly 2 lines.
