A writer reports a 30-second animated ad-auction explainer made by Claude Code, with a coded barcode mascot, drafted keyframes and a precisely timed stopwatch.
Reported by u/Efficient-Clock337 on RedditHow the agent did it
- Provide the article’s permitted facts, shot timings, palette and fonts.
- Have Claude plan the storyboard and draw original scene elements in code.
- Render keyframe drafts and review text legibility.
Where a person stepped in
The writer constrains the factual content and reviews draft stills. Their timing observation and the underlying article’s facts are not independently reproduced.
A writer gave Claude Code a detailed brief to illustrate their article about mobile advertising auctions. The agent produced a storyboard with scene timestamps and drew the visual elements in code: a walking barcode mascot representing an advertising identifier, phones, applications, bidding robots and a stopwatch.
The requested style combined sketch-like moving outlines with quick cuts, zooms and impact frames. Claude rendered draft keyframes before creating the full 1080p MP4 through FFmpeg. The author reviewed those stills and caught text that was difficult to read before the final render. The attached video metadata records a 30-second output, and the writer says the stopwatch stopped at the requested 0.100 seconds as the winning advertisement appeared.
The brief fixed the palette, fonts, shot timing and a permitted facts list. That gave the agent constraints it could check while planning and rendering, rather than asking it to invent a complete visual explanation from an open-ended topic. The author says no stock assets, specialist skills, MCP connections or manual video editor were involved. The source does not independently verify the article's advertising statistics or audience response. Its useful result is a specific animated explanation with reviewed legibility and constrained factual content, not proof that every generated claim or timing decision is correct.

Frequently asked questions
Which review caught a concrete problem?
Checking draft stills caught text that was difficult to read before the full render.
What constrained factual content?
The brief supplied a locked facts list and told the agent not to invent numbers; those facts still require source review.
Was a conventional editor used?
The author says no manual video editor, stock assets, MCP connection or specialist skill was used; FFmpeg rendered the coded animation.

Remaining steps
- Correct the stills before rendering the full MP4 with FFmpeg.
- Check the requested stopwatch timing in the completed video.
