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。

❌ "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"

Duration Guidelines

时长指南

Duration	Quality	Use For
2-3 seconds	Highest quality	GIFs, looping backgrounds, cinemagraphs
4-5 seconds	High quality	Social media posts, product reveals
6-8 seconds	Good quality	Short clips, transitions
10+ seconds	Quality degrades	Avoid unless stitching shorter clips

时长	画质	适用场景
2-3秒	最高画质	GIF、循环背景、活照片（Cinemagraph）
4-5秒	高画质	社交媒体帖子、产品展示
6-8秒	良好画质	短视频、转场
10秒以上	画质显著下降	除非拼接短片段，否则避免

Extending Duration

延长时长方法

For longer videos, generate multiple short clips and stitch:

bash

如需制作长视频，可生成多个短片段后拼接：

Cinemagraph 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
