- Content CredentialsA signed record (C2PA) of how the file was made, sealed so any change shows.
Google Cloud documentation lists Veo 2 to 3.1 among models whose images or videos are automatically signed with Content Credentials by Google LLC.
This statement covers Google Cloud's Gemini Enterprise Agent Platform, not the consumer Gemini app. Google does not give a start date.

Quoted passage How to Use Content Credentials; Supported models
If you generate a media file, such as an image, using a supported Google model, Content Credentials are automatically added and signed by Google LLC." "Content Credentials are supported by the following models. All images or videos created or modified using the listed models are automatically digitally signed by Google LLC. "Google Media Processing Services" is specified as the app or device used in the Content Credential. gemini-omni-1.1-flash-preview gemini-omni-flash-preview gemini-3.1-flash-lite-image gemini-3-pro-image gemini-nano-banana-2.1 gemini-3.1-flash-image gemini-2.5-flash-image virtual-try-on-001 veo-2.0-generate-001 veo-2.0-generate-exp veo-2.0-generate-preview veo-3.0-generate-preview veo-3.0-fast-generate-preview veo-3.0-generate-001 veo-3.0-fast-generate-001 veo-3.1-generate-preview veo-3.1-fast-generate-preview veo-3.1-generate-001 veo-3.1-fast-generate-001 veo-3.1-lite-generate-001 lyria-3-clip-preview lyria-3-pro-preview
- Invisible watermarkA signal woven into the pixels, frames, audio or wording, meant to survive copying.
Gemini API documentation and Google DeepMind's Veo page say videos made with Veo are watermarked with SynthID. In May 2024 Google DeepMind said the watermark is embedded in the pixels of every frame.
Quoted passage Watermarking
Watermarking: Videos created by Veo are watermarked using SynthID , our tool for watermarking and identifying AI-generated content. Videos can be verified using the SynthID verification platform.
Quoted passage responsibility section
It's crucial to introduce technologies such as Veo in a responsible way. To achieve this, videos made with Veo will be marked with SynthID, our advanced technology for watermarking and detecting content generated by AI.
Watermarking AI-generated text and video with SynthID
Quoted passage introduction; SynthID for video
Today, we’re expanding SynthID’s capabilities to watermarking AI-generated text in the Gemini app and web experience , and video in Veo , our most capable generative video model." "This technique embeds a watermark directly into the pixels of every video frame, making it imperceptible to the human eye, but detectable for identification." "Starting today, all videos generated by Veo on VideoFX will be watermarked by SynthID.
- 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.
No Google page read names an IPTC Digital Source Type term for its outputs.
- Visible markA mark you can see, such as a logo or a sparkle in a corner.
Not stated. None of Google's pages listed under Sources read says so.
Google describes visible marks for Veo video made in the Gemini app, Gemini Notebook and Flow, not for API output.
- Tool named in metadataThe tool or model written into ordinary file fields, such as Software or Creator.
Not stated. None of Google's pages listed under Sources read says so.
Limits and detection
- Checking tool from the makerA way the maker offers to check a file for its traces.
Gemini API documentation says Veo videos can be verified with the SynthID verification platform, which Google said on October 7, 2026 is available to everyone, globally in English.

We're making it easier to identify AI-generated content globally.
Quoted passage body
Since launching Google SynthID in 2023, we've helped people identify AI-generated media using imperceptible watermarks across images, video, and audio. To date, we've watermarked over 180 billion images and videos, along with 240,000 years of audio content." "Last year, we introduced an early version of the SynthID Detector to help media professionals verify AI-generated content. Now, we’re expanding access to everyone – with the tool available globally in English starting today.
