Type out my headline with Aceternity UI's Typewriter Effect (https://ui.aceternity.com/components/typewriter-effect; free component, Aceternity License, fine in commercial video, do not redistribute the source), centered in the frame. Install with npx shadcn@latest add @aceternity/typewriter-effect. TypewriterEffect reveals characters with a Motion stagger when the element enters view, and TypewriterEffectSmooth animates a width mask with whileInView; for a render, derive the number of visible characters (or the mask width) and the cursor blink from frame / fps (Remotion) or the HyperFrames timeline. Pass words as [{ text, className }] to color single words, and set cursorClassName for the cursor color.
