手绘与绘画

白板讲解

一块真白板，画面里没有手。马克笔自己飘着写。落笔处积一点墨。旧笔迹没擦干净。黑、红，再加一支蓝。样片《Einstein in Your Pocket》：手机怎么知道你在哪：GPS、原子钟，和相对论每天多出的 38 微秒。

这支样片是 Lemomo 用代码逐帧绘制的风格参考，不是下面这条提示词的 Seedance 成片。提示词按同一种画面语法写成，把故事换成你的再拍。

提示词

Seedance 2.5. 16:9. Style: Whiteboard Explainer (白板讲解).

Look: A real whiteboard, no hand in frame. A marker floats and writes. Ink pools where the pen lands. Faint old marks were not fully erased. Black, red, and one blue.
画面：一块真白板，画面里没有手。马克笔自己飘着写。落笔处积一点墨。旧笔迹没擦干净。黑、红，再加一支蓝。

Camera: One camera follows the pen for the whole film. No editorial cuts. Formulas appear in the order the voice says them. End by pulling out to the whole board.
镜头：一台摄影机跟着笔走完整支片子。不要剪辑。公式按旁白的词序写出来。结尾拉远看见整块板。

Sound: Clear explainer voice, marker squeak, the soft tap of the cap.
声音：清楚的讲解声、笔尖吱吱声、笔帽轻叩。

Story: replace this with yours. Sample film "Einstein in Your Pocket": How a phone knows where you are: GPS, atomic clocks, and the 38 microseconds relativity adds every day.
故事：把这里换成你的。样片《Einstein in Your Pocket》：手机怎么知道你在哪：GPS、原子钟，和相对论每天多出的 38 微秒。

About 30 to 45 seconds. Hold this look from the first frame to the last.
