Twilight on the River: A Poetic Journey

Create a 40-second, 16:9 cinematic ink-wash animation in the style of classical Chinese landscape painting, set on a river in early autumn of the Tang Dynasty. The video consists of four 10-second segments with seamless keyframe continuity—each segment must begin exactly where the previous one ended, maintaining identical composition, lighting, and environmental state, with time flowing continuously forward. Do not reset shots, repeat prior frames, or use jump cuts. Segment 1 (0–10s): "A Single Ray of Sunlight Spreads Across the Water" The setting sun hangs above distant mountains, casting golden-red slanted light across the river surface. Water ripples gently. Camera slowly pushes forward. End frame: sunset approaches the mountain ridge; river surface shows intertwined red and green tones. White serif Chinese subtitles centered at bottom: "一道残阳铺水中。" Gentle female Mandarin voiceover reciting the line; soft guzheng background music. Segment 2 (10–20s): "Half the River Jade-Green, Half the River Crimson" Continuing from Segment 1's end frame. The sun gradually sinks behind the mountain; half the river appears jade-green, the other half fiery red, water tones blending. Camera slowly pans right. End frame: sun completely sets; sky transitions to soft pink-purple twilight. White subtitles: "半江瑟瑟半江红。" Continued gentle voiceover and guzheng accompaniment. Segment 3 (20–30s): "How Pitiful the Third Night of September" Continuing from Segment 2's end frame. Twilight gradually fades; sky deepens to blue-purple. A thin crescent moon appears above distant mountains. Camera tilts slightly upward. End frame: blue-purple night sky, curved moon, deep teal river surface. White subtitles: "可怜九月初三夜。" Continued voiceover and guzheng. Segment 4 (30–40s): "Dew Like Pearls, Moon Like a Bow" Continuing from Segment 3's end frame. Camera slowly moves closer to the right riverbank's grassy edge. Crystalline dewdrops shimmer like pearls in the foreground. The crescent moon glows like a bow in the distance; the river surface remains tranquil. End frame: foreground dewdrops, middle-ground river water, background crescent moon; camera becomes static. White subtitles: "露似真珠月似弓。" Final voiceover and guzheng fade gently. Unified requirements: 16:9 landscape orientation; 4 segments of 10 seconds each; cinema-grade ink-wash animation in Tang Dynasty setting; same riverbank, distant mountains, reeds throughout; smooth, steady camera movement; white serif simplified Chinese subtitles (centered, lower third); gentle female Mandarin recitation of each poem line; delicate guzheng background music; video size under 20 MB. Absolutely prohibit: camera resets, image repetition, abrupt cuts, human characters, modern objects, or unrelated text. All four segments must form a natural visual continuum with accurate subtitles and clear voiceover.
