Google Gemini Launches AI Video Detection

The swift evolution of artificial intelligence in generating audiovisual content has escalated the need to differentiate between videos recorded by humans and those created or modified by AI. Addressing this critical concern, Google’s Gemini AI assistant now features an advanced tool for detecting videos generated or edited by its own AI technologies.

Get to Know Gemini and Its Latest AI Video Detection Feature

Gemini, Google’s versatile AI assistant, aids users with diverse tasks ranging from answering questions and creating text to producing visual and audiovisual media. In December 2025, Google unveiled a new video verification feature within Gemini. This enables users to upload videos and determine if they were produced or altered using Google’s AI systems.

How Does Google’s AI Video Detection Work?

This detection leverages SynthID, a sophisticated digital watermark embedded invisibly into the audio and individual frames of videos created with Google’s AI tools. This watermark preserves video quality and remains imperceptible to viewers, yet Gemini can detect it to authenticate the video’s origin.

Here’s the streamlined process for users:

• Upload videos up to 90 seconds in length and 100 MB in size.
• Ask Gemini, “Was this video generated using Google’s AI?”
• Gemini scans for the SynthID watermark within the video or audio.
• The assistant returns a clear answer, pinpointing watermark location or confirming its absence.

This method enhances transparency by reliably verifying if videos were created or manipulated by Google’s AI.

What Videos Does This Detection Cover?

SynthID detection is exclusive to videos generated or edited with Google’s official AI tools, including the Veo 3.1 model integrated within Gemini. Currently, it does not identify videos produced by AI software outside the Google ecosystem.

Important Limitations

• Only videos embedding the SynthID watermark—those made or modified via Google solutions—are detectable.
• AI videos from other providers remain undetectable by this feature.
• Video uploads must adhere to size and duration limits (max 100 MB, 90 seconds).

Why This Advancement Matters

With AI-generated videos growing rapidly, risks of misinformation and diminished trust arise. This detection tool offers significant benefits:

• Combating misinformation: Quickly verify if a video was AI-generated by Google before sharing.
• Boosting digital transparency: Media, researchers, businesses, and the public gain a reliable verification method.
• Fostering trust: Distinguishes between AI-assisted authentic content and fully fabricated videos, promoting a safer digital environment.

How to Use Google Gemini’s Video Detection

To get started, users need the Gemini app and a Google account. Steps to verify:

1. Open the Gemini app on your mobile device.
2. Access the video verification feature.
3. Upload a video within the supported parameters.
4. Ask, “Was this video created with Google’s AI?”
5. Receive a prompt response indicating SynthID watermark presence or absence.

The detection is swift and available worldwide in all Gemini-supported languages.

Inside SynthID: The Technology Behind the Watermark

SynthID embeds an invisible digital watermark directly into video and audio data, enabling authentication and fraud prevention. Serving as a discreet “signature” for AI-generated content within Google’s ecosystem, SynthID allows Gemini to reliably identify and verify AI-made videos.

Impact on Content Creators and Viewers

For creators utilizing AI, SynthID ensures transparent attribution and maintains authenticity. For viewers, it educates and protects by enhancing trustworthiness across social media, websites, and communication channels.

Google’s rollout of SynthID may also inspire broader industry adoption of verification standards, establishing dependable ways to identify AI-generated media.

Conclusion

Google’s Gemini AI assistant introducing video identification marks a pivotal step toward combining AI innovation with transparency and digital security. While currently limited to Google-generated content, this feature sets a foundation for tackling challenges posed by the surge in synthetic audiovisual media.

Professionals in video editing, journalism, digital marketing, and consumers seeking reliable content validation should take advantage of Gemini’s AI video detection to verify authenticity effectively.
