Summary
Peter Yang spends a week testing Anthropic’s new Sonnet 5.5 and shows seven examples of videos the model builds almost entirely from code. The demos range from a meme and a motion-graphics designer reel to an animated Claude mascot journey from the Stone Age to AGI, a product launch video, a vertical short, and edited talking-head footage.
The tutorial shares the prompts behind each result, including how a /goal command in Claude Code can push the model to keep iterating until output matches a reference video. It also shows the open-source Hyperframes repository, which Claude Code can install from a GitHub link, and how the model syncs animations to music and generates sound effects and background audio without extra tools. In the vertical short, the model found and added a British voice-over on its own after feedback, and the clip needed only a fix for some dark frames.
Along the way, Yang compares Sonnet 5.5 with Opus 5.5, arguing that video creation has become a standout use case for both models. The video is a practical starting point for creators and marketers who want to produce polished promotional videos with Claude Code.
