Google expanded Gemini’s AI verification feature to videos made or edited with the company’s own AI models. Users can now ask Gemini to determine if an uploaded video is AI-generated by asking, “Was this generated using Google AI?”
Gemini will scan the video’s visuals and audio for Google’s proprietary watermark called SynthID. The response will be more than a yes or no, Google says. Gemini will point out specific times when the watermark appears in the video or audio. The company rolled out this capability for images in November, also limited to images made or edited with Google AI.
Some watermarks can be easily scrubbed, as OpenAI learned when it launched its Sora app full of exclusively AI-generated videos. Google calls its own watermark “imperceptible.” Still, we don’t yet know how easy it will be to remove, or how readily other platforms will detect the SynthID information and tag the content as AI-generated. Google’s Nano Banano AI image generation model within the Gemini embeds C2PA metadata, but the general lack of coordinated tagging of AI-generated material across social media platforms allows deepfakes to go undetected.
Gemini can handle videos up to 100 MB and 90 seconds for verification. The feature is available in every language and location that the Gemini app is available.
