Meta is open sourcing a method to watermark AI-generated videos. Called Meta Video Seal, the company says it's robust against compression and edits. Video Seal isn’t the first technology of its kind. DeepMind’s SynthID can watermark videos, and Microsoft has its own video watermarking methodologies. In addition to a watermark, Video Seal can add a hidden message to videos that can later be uncovered to determine their origins. Meta claims that Video Seal is resilient against common edits like blurring and cropping, as well as popular compression algorithms.
