How to Render a Motion Graphics Video with Claude Opus 5.5: Prompt, Frame Renderer, ffmpeg and Real Cost
Claude Opus 5.5 cannot output a single pixel, yet people keep posting motion-graphics videos "made by Opus 5.5". The trick is that the model writes a program that draws every frame, and you render that program into an MP4. This post is the full, reproducible pipeline we used for a 12-second 1280x720 promo: the exact prompt, the API call, a 25-line frame renderer, the ffmpeg command, and what it…
To create a motion graphics video using Claude Opus 5.5, follow this five-step pipeline. First, write a precise prompt defining the HTML structure and rendering function. Then, call Opus 5.5 through an API endpoint with streaming to ensure the connection stays open during the lengthy model response. Save the returned HTML file and open it to verify a preview loop. Finally, render each frame using headless Chrome in a custom script.
