I built a sample 30-second promo for a placeholder architecture, interiors and planning studio, cut to a written script and a 7-shot list. It opens with an animated logo reveal, runs two sketch-to-render transitions (a house elevation and a site plan drawn in pencil, then brushed into the render on the same lines), cuts a still interior photograph with light and dust moving across it between a dusk exterior dolly and an aerial orbit, and closes on an end card. The file is 30.0 s, 900 frames at 1920x1080 and 30 fps, H.264 with an AAC music and sound-design bed at -14.0 LUFS; 0.0% of frames repeat the frame before them. All imagery is placeholder material standing in for a firm's own photography and footage.
