Ask HN: How to Generate Animations Programatically?

I have a task to generate an animation programatically. There is one animation and a list of names, for which I need to generate separate animations. What is the best way to do this? I'm thinking about creating the base animation (with sound) in SVG and create one for each name, then capturing the animation into mp4. Since this is the first time I try to generate videos programatically, I wonder if there is a better way to do this.
