转描速写动画Rotoscope sketch animation

真人参考动作被整段转描成连续手绘线条，线条随帧轻微跳动。与「手绘生物闯入实拍空间」不同：这条不叠加实拍画面，全片都是转描后的线稿。

A live-action reference performance is fully rotoscoped into continuous hand-drawn linework, boiling gently frame to frame. Unlike the hand-drawn/live hybrid template, nothing live-action stays visible — the whole frame is rotoscoped line art.
