Make a cinematic 10-second film in Blender: a red dragon with a rider on its back flying fast through a deep Norwegian fjord, seen from a chase camera that swoops around it. Steep grey cliffs with snow on the peaks, a still dark lake that mirrors the cliffs and the dragon, low mist and soft morning light breaking through the clouds. The dragon beats its wings, banks low over the water, and near the end breathes a long stream of fire. Build the dragon, rider, fjord and sky yourself in Blender. Render a 10-second 1280x720 film with the dragon 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 hyper-realistic, like a shot from a big-budget fantasy film, the moment it loads.
