Same invented business, same phone number, two different creative directions — built so they can be compared honestly. Both are 16:9 and both run inside 25–30 seconds. The muted cut is the primary deliverable in each case, because these autoplay without sound; the voiceover cut is the secondary.
Four 8-second generations, each anchored to clean isolated character renders so the cast survives the cuts. The hero beat is the whole ad: he walks into the geyser, turns one valve, and the water stops dead.
Four things went wrong and were fixed, not hidden. The first pass of the hero shot produced an unmistakable Mario likeness — cap emblem, dungarees, white gloves; "plumber + big mustache + cap" is the model's strongest attractor, so the character was redesigned around a beard and a navy work shirt. The homeowner changed into a different person between shot 1 and shot 2. The kitchen changed four times in one continuous story. And the plumber's idle hand rendered as a fingerless club while his other hand had five fingers.
The reference images alone did not hold any of it. What did: restating every identity fact in every prompt, locking the room with a real frame from shot 1 as the reference, and putting a toolbox in the idle hand so there was no free hand left to deform. The last of those is the fix for the single thing Boban predicted in advance — fingers are what these models are worst at.
Deliberately plain: a dripping tap, a blocked plughole, a shower barely running, a joint leaking under a sink where nobody can see it — then the tap running clean. Every shot is locked off and only the water moves.
Every scene carries an object only a plumber touches. That is the rule added after the version you killed, which read as a roofing ad because four of its five shots were ceiling damage. There is no ceiling anywhere in this one.
