诀窍不是从提示词开始。

The trick was not starting with a prompt. I started with a production board. 12 shots. 2 characters. 1 emotional object. Simple dialogue. Clear camera notes. The storyboard became the “visual contract” for the AI, so the characters, framing, and emotion stayed consistent. A useful lesson from making this: AI video consistency is mostly a pre-production problem. If the model has to invent the character, camera, setting, and emotion every shot, it drifts. If you give it a storyboard with clear acting beats, it behaves much more like a production tool. -------------- Story board Prompt Create one single horizontal 16:9 sketch-style animation development board for an original emotional short film titled “Lantern for the Fireflies.” The board must be a black-and-white pencil pre-production storyboard page, not a color illustration. Use expressive rough animation drawings, visible construction lines, grayscale shading, handwritten production notes, blue camera movement arrows, red shot numbers, timing marks, lens notes, and dialogue captions under each frame. Create fully original characters. Do not imitate or resemble any existing animated film characters or copyrighted designs. Use an original warm 3D animated family-film character language: rounded expressive faces, soft proportions, clear silhouettes, emotional acting, simple readable shapes. STYLE Sketch-only animation storyboard. No polished color keyframes. No full-color rendering. Soft graphite texture, gray marker shadows, rough thumbnail energy, clean readable 12-panel layout. LAYOUT Horizontal 16:9 board. 12 storyboard frames arranged in a clean 4x3 grid. Two characters only. Keep both characters consistent across all shots. CHARACTERS Mina: An original shy girl around 10 years old. Short dark bob haircut, round expressive eyes, small nose, soft cheeks, oversized rain jacket, knee-length shorts, worn sneakers. She is quiet, careful, and misses her grandmother. Tomo: Mina’s younger brother, around 6 years old. Fluffy short hair, big curious eyes, oversized striped shirt, small backpack, sandals. He is gentle, curious, and emotionally honest. Prop: A broken paper lantern with a bamboo frame, torn paper side, small handle, and a warm candle inside. It belonged to their grandmother. The lantern is the emotional center. Environment: Summer evening garden near an old countryside house. Tall grass, stone path, hydrangeas, trees, distant rice fields, fireflies appearing after dusk. 12 STORYBOARD SHOTS WITH DIALOGUE 1. Wide shot. Mina and Tomo stand beside the old garden shed. Mina holds the broken lantern. Dialogue Mina: “Grandma used to light this every summer.” Camera note: 24mm wide, locked-off. 2. Close-up. Tomo touches the torn paper gently. Dialogue Tomo: “Can we fix it?” Camera note: 50mm close-up, tiny hand movement. 3. Medium shot. Mina looks unsure, holding the bamboo frame. Dialogue Mina: “I don’t know if it will still glow.” Camera note: slow push-in. 4. Insert shot. Their hands patch the lantern paper with tape. Dialogue Tomo: “Then we help it glow.” Camera note: top-down close-up. 5. Medium two-shot. The candle flickers but almost goes out. Dialogue Mina: “Careful...” Camera note: 35mm, low table height. 6. Close-up. Tomo shields the flame with both hands. Dialogue Tomo: “I’m being the wind wall.” Camera note: locked close-up, gentle acting. 7. Wide shot. The repaired lantern glows softly in the garden. Dialogue Mina: “It worked.” Camera note: slow dolly push. 8. Close-up. Mina sees the first firefly near the lantern. Dialogue Tomo: “Look.” Camera note: rack focus lantern to firefly. 9. Medium shot. More fireflies gather around them. Dialogue Mina: “They remember the light.” Camera note: slow upward tilt. 10. Close emotional two-shot. Tomo leans against Mina. Dialogue Tomo: “Do you think Grandma sees it?” Camera note: 50mm, shallow depth. 11. Close-up. Mina smiles with tears in her eyes. Dialogue Mina: “Maybe she sent them.” Camera note: slow push to face. 12. Wide ending shot. Mina and Tomo sit together under the glowing lantern as fireflies fill the summer garden. Dialogue Tomo: “Then let’s keep it lit.” Camera note: 24mm wide, hold for 2 seconds. The final board should feel like a real animation studio sketch storyboard for a tender family short about memory, grief, repair, and comfort. Seedance 2.0 animation prompt TITLE Lantern for the Fireflies REFERENCE Use the uploaded 12-shot sketch storyboard as the main visual reference. Preserve the two original character designs, lantern design, summer garden setting, shot order, emotional acting, and dialogue beats. Do not add extra characters. Do not change the story. STYLE Original warm 3D animated family-film look. Rounded expressive characters. Soft tactile materials. Gentle facial acting. Warm lantern light. Blue dusk environment. Fireflies as small natural glowing points. No logos, no subtitles, no text overlays. DIALOGUE RULE One speaker per shot. Keep mouth movement subtle and clear. When one character speaks, the other listens silently. AUDIO Soft summer ambience. Distant cicadas. Small candle flicker. Gentle grass movement. No background music unless very faint warm piano pad is desired. TIMELINE 12 shots, 15 seconds total. Each shot lasts about 1.2 seconds. Final shot holds slightly longer.

诀窍不是从提示词开始。 我是从制作板开始的。 12 个镜头。 2 个角色。 1 个情感道具。 简洁的对白。 清晰的镜头说明。 分镜脚本成为了 AI 的“视觉契约”，因此角色、构图和情绪始终保持一致。 从这次制作中得到的一个有用教训： AI 视频的一致性主要是前期制作的问题。 如果模型需要在每个镜头中凭空创造角色、镜头、场景和情绪，画面就会漂移。 如果你给它一份带有清晰表演节拍的分镜脚本，它就更像一个制作工具了。 -------------- Story board Prompt（分镜脚本提示词） Create one single horizontal 16:9 sketch-style animation development board for an original emotional short film titled “Lantern for the Fireflies.” The board must be a black-and-white pencil pre-production storyboard page, not a color illustration.
