Dev makes a cinematic Claude ad entirely in Claude, open-sources the workflow plugin

A Reddit user shares how they made a 16:9 cinematic spec commercial for Claude entirely inside Claude Design—no After Effects, no motion software.

Key takeaways:

Build a kit before prompting: isolate objects one per file, and split the official logo mark into its real layers so the film assembles it rather than cutting to it. Builds fail on missing assets, not prompt length.
Directing loop: Claude handled scene structure, animation timing and typography; the author directed it beat by beat and rebuilt parts that didn't land.
The plugin is Emulo (open source): it reads your Claude Code and Codex session history and loads it before the agent writes anything, removing the need to re-explain your workflow in every new session. It started with code, design and writing, with the video workflow added recently.

The author is not affiliated with Anthropic; they picked a brand they like to test how far motion could go. GitHub: github.com/ohad6k/emulo
