GSAP
3Blue1Brown 给我留下了深刻印象。利用动画制作视频，内容简洁，演示清晰。前两天刚好碰到一件事，我就顺便学习了一下怎么用代码做动画。
以javascrip为例，有两个动画引擎，GSAP和Animajs。由于网速的原因，询问了GPT后，我选择了GSAP来制作我的第一个动画视频。
制作动画视频不同于动画，要协调多个动作，还需要对齐时间，所以使用时间线Timeline是必要的。
需要两条时间线分别播放字幕和动画，这需要协调好他们
而且很多片段需要后期调整，所以也必须使用相对时间>，<,label这三种模式。
制作动画重要的是想好脚本，然后声明HTML元素，再恰当时刻将元素呈现出来

视频观看
我录制运行结果后，又通过tts给视频配了音，发布在了bilibili ，欢迎来查看效果
不过要吐槽的是B站把60帧的选项给搞没了，投上去的720P60帧视频全都变成了30帧
导致高速动画效果惨不忍睹，要是没有大会员，那观看起来真的不太好
