竹林の武士対決：Runway 4.5とKling 2.6

原文プロンプト

"The camera orbits around Two samurai in traditional armor face each other in bamboo forest. Shafts of morning light cut through mist. At 1s, both explode forward simultaneously. 2s: katanas meet in center frame, steel rings out, impact sends visible shockwave through mist. 2.5-4s: rapid exchange of three strikes, blades catching light with each swing. 4.5s: they pass each other, freeze in opposing stances. Kurosawa framing, high contrast black and white with selective color on blood-red cord details."
