NVIDIA Synthetic Video Detector – a new AI service for detecting generated videos - 2026
NVIDIA Synthetic Video Detector (SVD) is an AI-powered microservice developed by NVIDIA for automatically detecting videos created or modified by generative AI models. The solution is part of the NVIDIA AI for Media platform and was unveiled at SIGGRAPH 2026.
Description
Synthetic Video Detector is an AI microservice from the NVIDIA NIM family that analyzes video streams frame by frame and computes the probability that the video was fully or partially created by generative models.
Unlike traditional metadata or digital signature verification tools, the system analyzes low-level statistical image features characteristic of modern video generation models (diffusion models and other generative neural networks).
After analysis, the service produces:
- per-frame probability of artificial origin;
- an overall score for the entire video;
- a classifier score that can be used in automated content verification workflows.
Key Features
Frame-by-Frame Analysis
Each frame is analyzed independently, making it possible to detect:
- fully synthetic videos;
- partially modified videos;
- DeepFake inserts;
- locally altered scenes.
Resilience to Post-Processing
One of the key features is the model's robustness to common video processing operations:
- re-encoding;
- resolution changes;
- scaling;
- cropping;
- heavy compression.
This is especially important since most videos on the internet undergo several transcoding stages before publication.
Detection Accuracy
According to NVIDIA's internal testing, the service achieves the following accuracy rates:
| Video type | Accuracy |
|---|---|
| No compression | up to 92 % |
| ~15 % compression | 87 % |
| ~50 % compression | 82 % |
Even under heavy compression, detection quality remains high enough for use in automated moderation systems.
Performance
Synthetic Video Detector is optimized for NVIDIA GPUs.
| Hardware platform | Full HD analysis time |
|---|---|
| NVIDIA RTX | ~22 ms |
| NVIDIA L40 | ~30 ms |
This speed enables near-real-time operation when processing large video data streams.
Use Cases
Media & Newsrooms
Newsrooms can automatically verify video materials before publication. When suspicious footage is detected, the system can:
- flag the material for additional review;
- temporarily block publication;
- notify editors.
Fact-Checking
Fact-checking organizations gain an additional tool for analyzing video evidence.
Digital Forensics
The technology can be used by experts investigating:
- DeepFake proliferation;
- fraud;
- information warfare;
- tampered video evidence.
Social Media
Platforms can automatically detect suspicious videos before users publish them.
Corporate Security
Companies can verify video materials used in internal investigations and monitoring systems.
Integration into Editorial Workflows
According to NVIDIA, the service does not replace existing verification procedures. Instead, it serves as an additional signal source that enables:
- faster sorting of incoming video streams;
- prioritization of the most suspicious materials;
- reduced workload for specialists;
- accelerated decision-making in breaking-news scenarios.
Availability
As of the announcement, Synthetic Video Detector is distributed as an NVIDIA NIM Microservice.
To use it, you must join the AI for Media Private Access Program, after which you can obtain access to the NIM container and API for integration into your own systems. It supports deployment via Docker using NVIDIA GPUs.
Example launch command:
docker pull nvidia/nim-synthetic-video-detector docker run --gpus all -p 8000:8000 nvidia/nim-synthetic-video-detector
Conclusion
As generative models continue to improve, distinguishing real videos from AI-generated ones becomes increasingly difficult. NVIDIA Synthetic Video Detector is a specialized tool that automatically analyzes video materials and assesses the likelihood of their artificial origin.
Although the developers emphasize that the service is not definitive proof of tampering, it can significantly accelerate the work of newsrooms, digital forensics experts, and content moderation systems, serving as an additional layer of protection against the spread of synthetic videos.
