折叠成型教学视频的拍摄要点
标签：教学视频, 拍摄, 机位, 慢动作
折叠成型镜头语言要点：①主俯双机位，俯拍展示折叠线布局、侧拍展示折起角度；②折起瞬间用 120 fps 慢动作呈现金属延展回弹；③特写对准折痕用侧逆光突出棱线。关键信息卡（折叠角度、退火温度）以字幕随动作出现。示例成片结构：30 s 引入成品 → 3–5 min 单一基础折 → 2 min 复合折。分段拍摄配合分段退火节奏，避免长时间录制中坯料硬化失真。
Fold-forming video language: ① top-down plus side cameras—top shows fold-line layout, side shows fold angle; ② shoot the fold moment at 120 fps slow motion to reveal stretch and springback; ③ macro on the crease with side-backlight to pop the ridge. Data cards (fold angle, anneal temperature) appear as captions. Sample structure: 30 s finished-piece intro, 3–5 min single basic fold, 2 min compound fold. Shoot in segments matched to annealing rhythm to avoid distortion from work-hardening during long takes.
