What they did
The author wanted a short YouTube video comparing two slow, sightseeing routes from Great Falls, Montana to Orlando, Florida. They first had Claude help draft a detailed brief, then handed it to Claude Fable 5.2 the day after its release. The brief set the format (1080p, 30 fps, 60 to 90 seconds, MP4), a six-scene sequence, two coloured routes that follow real highways, a pin and a fact card for each stop, a comparison card with miles and hours, and a style meant to read well on a phone. It listed candidate attractions but told the model to check each one was real, open and near the route, swap in better ones, and show still frames for approval before rendering the full video.
How it went
The finished video runs 1 minute 29 seconds and follows the requested scene order. Each route got seven stops. The model kept most of the suggested classics, dropped two, and added five of its own, such as Devils Tower on the way to Mount Rushmore. The comparison cards gave about 2,950 miles for one route, 2,720 for the other and 2,490 for the fastest drive, all marked approximate. The author uploaded it to YouTube and says a job like this used to take hours in mapping and animation tools.
Worth knowing
The harness was not named, only the model, so it is not clear what tools rendered the MP4. The author advises spot-checking mileage and attraction facts in a mapping app before publishing. Asking for still frames first let them approve the look before paying for a full render.
