Quoted passage Will my generations contain a watermark?
All outputs generated in Google Flow using Veo, Omni, or Nano Banana include invisible SynthID watermarks. SynthID identifies AI-generated content by embedding digital watermarks directly into AI-generated content. To further help you identify AI-generated content, a visible watermark can be added to generated images and videos. You can control this with the “Visible watermarking” toggle in the drop-down menu under your profile picture. A visible watermark will be applied automatically for users in India, South Korea, and Vietnam who are not on the Google One AI Ultra 20x Plan.
- AI label in metadataA plain metadata field (IPTC Digital Source Type) saying AI made the content. Anyone can add or remove it.
Not stated. None of Google's pages listed under Sources read says so.
- Visible markA mark you can see, such as a logo or a sparkle in a corner.
Google Flow Help says a visible watermark can be added, controlled by a toggle, and is applied automatically in India, South Korea and Vietnam unless the user is on the AI Ultra 20x plan.
