Make a cinematic 10-second film in Blender: a small steel patrol boat ploughing through a rough open sea, seen from a low chase camera just behind and to one side of it. Big rolling swells with foam and spray, a white wake behind the boat, dense sea fog, tall dark cliffs fading into the mist, and heavy storm clouds with the sun breaking through and glittering on the water. Over the 10 seconds the light shifts from bright misty silver to a dark stormy dusk, and the boat's deck lights come on. The boat pitches and rolls on the swells and the camera follows it. Build the boat, sea and sky yourself in Blender. Render a 10-second 1280x720 film with the boat in frame from frame 0. Save film.mp4, four still frames and the .blend. Make index.html that plays film.mp4 muted, autoplay and looped, full width, with the stills below it. It should look like a shot from a big-budget game trailer the moment it loads.
