Claude Opus 5.5 Generates Fully Animated Videos by Writing Code, Not Pixels

Anthropic's Claude Opus 5.5, released September 22, 2026, can produce complete animated videos—complete with neural network visualizations, synchronized text overlays, and motion graphics—entirely by writing code rather than generating video pixels directly. The model transforms text prompts into animation code, which is then rendered frame-by-frame by a headless browser and encoded into MP4 files using ffmpeg, enabling creators to produce professional-quality motion graphics without traditional video editing software.
