One continuous shot. No voiceover, no stock, no talking head. The thing your product actually does, shown at a speed a person can follow. Everything below runs at 60fps, built frame by frame rather than filmed.
A single unbroken move from first mark to finished object. No cut anywhere in it, which is the hard version: every transition has to be caused by something on screen rather than hidden in an edit.
Made to launch my own developer tool, which meant it had to explain an abstract idea with nothing physical to point a camera at. The answer was to treat the interface itself as the object and let it assemble on screen.
Built from a reusable parts kit rather than one-off assets, so the same system produces the next film in hours instead of days. That is the part that makes a fixed price honest.
Most product video quotes are a discovery process wearing a price tag. This is the opposite. One product, one flow, one film, agreed before anything starts.
