Prompting Best Practices
提示词编写最佳实践
The Golden Rule: Subtle > Dramatic
黄金法则：细微 > 夸张
AI video models produce better results with gentle, subtle motion than dramatic action. Requesting too much movement causes distortion and artifacts.
❌ "person running and jumping over obstacles while the camera spins"
✅ "person slowly walking forward, gentle breeze, camera follows alongside"
❌ "explosion with debris flying everywhere"
✅ "candle flame flickering gently, warm ambient light shifting"
❌ "fast zoom into the eyes with dramatic camera shake"
✅ "slow dolly forward toward the subject, subtle focus shift"AI视频模型在处理轻柔、细微的运动时效果远好于夸张动作。请求过多运动会导致画面扭曲和伪影。

undefinedCinemagraph Effect
活照片（Cinemagraph）效果
A cinemagraph is a still photo where only one element moves (e.g., waterfall moving in an otherwise frozen scene). To achieve this:
- Generate the still image with the motion element clearly defined
- Prompt for motion only in that specific element
- Keep to 2-4 seconds for seamless looping
bash
infsh app run falai/wan-2-5-i2v --input '{
"prompt": "only the waterfall is moving, everything else remains perfectly still, water cascading smoothly, rest of scene frozen",
"image": "waterfall-scene.png"
}'活照片是指仅一个元素运动的静态照片（例如：瀑布流动，其余场景保持静止）。实现方法：
- 生成静态图片时，清晰定义需要运动的元素
- 仅为该特定元素编写运动提示词
- 时长控制在2-4秒，以实现无缝循环
bash
infsh app run falai/wan-2-5-i2v --input '{
"prompt": "only the waterfall is moving, everything else remains perfectly still, water cascading smoothly, rest of scene frozen",
"image": "waterfall-scene.png"
}'Common Mistakes
常见错误
| Mistake | Problem | Fix |
|---|---|---|
| Too much motion requested | Distortion, artifacts, warping | Subtle > dramatic, always |
| Wrong model for content type | Poor results | Use selection guide above |
| Clips too long (10s+) | Quality degrades significantly | Keep to 3-5 seconds, stitch if needed |
| No camera movement specified | Random/unpredictable motion | Always specify camera behavior |
| Conflicting motion directions | Chaotic, unnatural | One primary motion direction |
| Low-res source image | Low-res video output | Start with highest quality source |
| Complex action scenes | Models can't handle | Keep motion simple and natural |
| 错误 | 问题 | 解决方法 |
|---|---|---|
| 请求过多运动 | 画面扭曲、伪影、变形 | 始终遵循“细微 > 夸张”原则 |
| 模型与内容类型不匹配 | 效果差 | 参考上方模型选择指南 |
| 片段过长（10秒+） | 画质显著下降 | 控制在3-5秒，如需长视频则拼接短片段 |
| 未指定镜头移动 | 随机/不可预测的运动 | 始终明确镜头行为 |
| 运动方向冲突 | 混乱、不自然 | 仅设置一个主要运动方向 |
| 低分辨率源图片 | 视频输出分辨率低 | 从最高画质的源图片开始 |
| 复杂动作场景 | 模型无法处理 | 保持运动简单自然 |
