Cinematic Storyboard Generator#

Generate professional, cinema-grade image prompts for AI generation platforms (LibTV/LibLib, 即梦, Seedance, etc.).

Quick Start#

Every shot prompt must contain these 7 elements (in order):

text

日夜景 · 主体描述 · 空间坐标 · 镜头形式 · 光影设计 · 情绪落点 · 资产锚点

Example:

text

夜 · 男主立于城楼最高处，深褐短发金色发带，灰色对襟长袍金色云纹刺绣，拂尘横握 · 身后城墙延展，脚下士兵阵列，前景地面 · 远景 · 低角仰拍 · 固定镜头 · 侧逆光，金色月光从左侧45度打入，硬光，冷蓝#8899BB · 肃穆 · 战意凝聚 · 参考：宿迁_霸王故居_场景图.png + 定妆照_季沧海.png

Four Iron Rules#

Rule 1: Asset Anchoring#

• Character description MUST reference actual costume photo (定妆照)
• Scene description MUST reference actual scene image file
• Never imagine what an asset looks like — if you haven't seen the photo, don't write details
• Append asset paths at end of every prompt

Rule 2: Light Logic#

• Single main light only — never write multiple light sources
• Direction must be specific: "侧逆光从右侧45度打入" — not "自然光"
• Contact shadows required: "投影落地面，方向与光源一致" — characters don't float
• Back/side lighting preferred — frontal soft light = AI feel = fake

Rule 3: Material Consistency#

• Skin: "真实皮肤纹理，无磨皮无柔光" — not "细腻白皙"
• Clothing: "有重力垂坠感，真实褶皱，非贴图感"
• Scene-character same rendering space: "三层可信纵深：前景地面反光 → 中景人物 → 远景建筑轮廓"

Rule 4: Spatial Coherence#

• Characters stand on ground with physically correct shadows
• Three-layer depth: near ground reflection → middle ground character → far ground scene outline
• Portal/doorway as spatial boundary — not VFX effect rings
• Scale reference: character height ~1/5 of frame in wide shots

Shot Sequence Design#

Step 1: Analyze the Scene#

• Read the script/description
• Confirm emotion curve (what does the audience feel at this moment?)
• Identify key action and turning point

Step 2: Confirm Assets First#

• View all relevant costume photos (定妆照)
• View all relevant scene images
• Establish main light direction based on time of day
• Mark asset paths before writing prompts

Step 3: Build the Sequence#

Write prompts one by one. Each prompt is independent and complete.

Sequence PositionPurposeShot TypeOpening (1-3)Establish atmosphere, introduce settingWide/establishingMiddle (4-N)Develop tension, reveal detailsMedium/close-upClimax (N-2)Emotional peakClose-up/extreme close-upEnding (last 1-2)Release, transitionWide/freeze frame

Step 4: Quality Check Each Prompt#

Before finishing, verify:

• Day/night marked in first clause
• Character description matches costume photo
• Scene has specific asset anchor
• Light direction is specific (no "自然光")
• Character has ground shadow (not floating)
• Skin texture without retouching
• Clothing has weight/draping
• Three-layer depth is physically coherent
• Shot type matches emotion
• Asset paths annotated at end

Scene Type Reference#

Ancient/Fantasy (古装/仙侠)#

Light frameworks:

TimeMain LightShadowTextureMorningSide backlight, golden #D4A574Cool blue #4A3F6BDust visible in light beamsDuskSide light, orange-red, low angleDeep orange to blue-purpleLong shadows, golden rim lightNightMoonlight, cool blue #8899BB + lantern warm orange #FF6B35Cold-warm contrastVolumetric light, mist

Common scenes:

• Temple/mountain: Stone steps, cloud sea, ancient bells, pine trees
• Battlefield: Yellow earth, cracked, broken banners, dust, rusty metal weapons
• Interior: Wood structure, rammed earth walls, paper windows, bronze vessels

Modern Short Drama (现代短剧)#

Light: Natural interior light, window light with side backlight preferred. Avoid frontal soft light.

Scenes: Apartment, office, street, convenience store — real environments with specific details.

Overseas Format#

Style: Realism, natural color grading, no stylizing filters. Skin texture realistic-level.

Frame: 9:16 vertical (short drama format) or 16:9 horizontal (film).
