integrated_multimodal_description: [Shot 1] btssetstyle, photorealistic live-action behind-the-scenes footage. A single static wide portrait shot shows a full-scale ice-cave set inside a soundstage. Translucent blue ice walls, artificial snow and a narrow rocky ledge surround one adult female performer wearing a red expedition jacket, dark trousers and climbing boots. Large wind machines, overhead snow dispensers, lighting stands and ceiling trusses remain visible around the scenery. An off-screen adult male director with a firm, natural voice (S1) calls: <d>[English] And action!</d> A powerful gust drives artificial snow diagonally across the cave. The performer bends her knees, grips the rock beside her and raises her free forearm to shield her face. Her jacket and loose hair react naturally to the wind. Snow collects on her shoulders and the ledge. The gust weakens and she lowers her arm while maintaining her footing. The director (S1) calls: <d>[English] Cut!</d> No applause or cheering. non_diegetic_music: N/A
