最佳实践

添加水印
  • 不透明度：低调的品牌标识建议使用 20-40% 的不透明度，醒目的保护水印建议使用 50-70%
  • 尺寸：徽标水印宽度保持在视频宽度的 5-15%，以呈现专业效果
  • 位置：通常放在底部角落；除草稿或预览外，避免放在中央
  • 对比度：为水印添加阴影或描边，使其在不同背景上清晰可见
  • 一致性：所有内容均使用相同的水印设置
移除水印
  • 质量：源视频质量越高，移除效果越好
  • 简单背景：位于简单／均匀区域上的水印更容易移除
  • 多个水印：指定所有水印的位置，以便彻底移除
  • 合法使用：仅移除你拥有或已获授权内容中的水印

模式选择

生成前请询问用户：

“你想要快速且低成本，还是高质量？”

模式适用场景速度质量
max最终输出、专业内容、移除水印较慢最高
eco批量处理、草稿、测试位置较快良好

多轮水印迭代

使用 session_id 优化水印位置：

# Initial watermark
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Add my logo watermark to this video in the bottom right corner"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "watermark-project-001",
    "image_urls": ["https://example.com/my-video.mp4", "https://example.com/logo.png"]
  }'

# Adjust based on feedback
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "The watermark is too large and too opaque. Make it 50% smaller and reduce opacity to 25%"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "watermark-project-001"
  }'

# Final adjustment
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Move it slightly more to the center to avoid the video controls overlay area"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "watermark-project-001"
  }'
