Wan v2.1 Watermarking

Alibaba implements watermarking in Wan-generated content:

Video Watermarks

• Temporal watermarks - Patterns embedded across video frames
• Spatial watermarks - Per-frame invisible markers
• Audio watermarks - If audio is generated, it may contain markers
• Metadata embedding - Container-level identification

Characteristics

• Designed to survive video compression
• Resistant to cropping and resizing
• Maintained through format conversion
• Detectable by specialized video analysis tools

Detecting Wan v2.1 Content

AI video detection for Wan v2.1 involves multiple analysis methods:

Frame-Level Analysis

• Statistical patterns in individual frames
• Diffusion model artifacts
• Characteristic noise distributions

Temporal Analysis

• Motion consistency patterns
• Frame-to-frame transition artifacts
• Temporal frequency signatures

Watermark Detection

• Alibaba-specific watermark signatures
• Cross-frame pattern correlation
• Metadata inspection

Detection Accuracy

• Watermarked videos: 80-90% detection
• Processed videos: 60-75% detection
• Heavy compression: 50-65% detection

Video vs Image AI Detection

Video detection differs from image detection in several ways:

Aspect	Image Detection	Video Detection
Data Points	Single frame	Multiple frames
Temporal Analysis	N/A	Critical
Watermark Complexity	2D patterns	3D patterns
Processing Time	Fast	Slower
Accuracy Potential	Lower	Higher

The temporal dimension in video provides additional detection signals, making AI video detection potentially more accurate than image detection.

Removing Wan v2.1 Detection Markers

For Video Watermarks

1. Frame-by-frame processing - Apply removal to each frame
2. Temporal filtering - Target cross-frame patterns
3. Re-encoding strategies - Specific codec and bitrate choices
4. Neural video reconstruction - AI-based regeneration

Challenges

• Processing time increases with video length
• Quality loss more noticeable in motion
• Temporal consistency must be maintained
• File sizes can be significant

Best Practices

• Process at original quality before compression
• Maintain frame rate consistency
• Use appropriate codecs (H.264, H.265)
• Verify results across multiple frames
