Upload multiple images or videos to verify DCT spread-spectrum and VideoSeal AI watermarks
Images: DCT spread-spectrum watermarks embedded in frequency domain - survives JPEG compression, editing, and social media processing.
Videos: Meta's VideoSeal AI watermarks - production-grade neural network watermarking that survives re-encoding and format conversion.
Any detected watermark is SUCCESS - regardless of percentage! The "Signal Strength" percentage shows how much compression your video survived. Lower percentages (30-70%) are normal and expected for videos shared on social media, downloaded, or re-encoded. VideoSeal is designed to work even after aggressive compression that would destroy traditional watermarks. If we detected it, your content is protected.
