Most "AI video" tools generate pixels you cannot edit. If you want a product launch video where the text is exactly your copy, the colors are your brand and you can change one word next week, you want the video to be code.

HyperFrames from HeyGen does that. A video is an HTML file with a few data attributes for timing and tracks. The renderer seeks every frame in headless Chrome and encodes with FFmpeg, so the same input always gives the same MP4. Because the format is plain HTML, coding agents are good at writing it, and the project ships skills that teach Claude Code, Codex, Cursor and Gemini CLI the production loop.

This guide gets you from zero to a rendered launch video with Claude Code, then shows the manual CLI route.

Before you start
