Cast & Render ties a full-screen video to the scroll bar. As visitors scroll, the video moves frame by frame while three headline panels fade in, drift and hand off to each other.

• Precise scrubbing. Eased seeking turns jumpy scroll input into smooth motion.
• Fast start. The video is preloaded behind a progress bar so the scrub never stutters.
• Editable timeline. Each panel's fade points sit in one short list you can retime for your own footage.
• Mobile ready. Breakpoints for phones and landscape screens, plus the iOS first-frame fix.
