Face Swaps
Detect replaced faces in videos with temporal consistency analysis across frames
Free online video check
Free Deepfake Video Detector
Upload an MP4 to check for AI-generated footage, face swaps, lip-sync manipulation, and other deepfake signals. Review a probability score with supporting evidence.
What We Detect
Comprehensive video manipulation and deepfake detection
Lip Sync Manipulation
Identify mismatched audio and lip movements using cross-modal analysis
Generative Video
Detect fully AI-generated video content from diffusion and autoregressive models
Face Reenactment
Identify puppeteering and facial reenactment attacks with motion analysis
Splicing & Editing
Detect edited, spliced, or composited video segments with temporal forgery detection
Deepfake Artifacts
Identify subtle generation artifacts like flickering, blurring, and inconsistency patterns
Explainable Evidence
Understand exactly why content was flagged
Evidence Types
- Frame-level bounding boxes for detected manipulations
- Temporal inconsistency heatmaps across video timeline
- Confidence bands with calibrated probability estimates
- Signal breakdown (lip-sync, temporal, artifact analysis)
Operational Guidance
- Processing time depends on video length and resolution
- Async and batch workflows are available
- Review confidence together with frame-level evidence
Limitations & Best Practices
Understanding model constraints for optimal results
False Positive Risk
Highly compressed videos, low-quality footage, or heavy motion blur may increase false positive rates. Use confidence bands to set appropriate thresholds for your use case.
Adversarial Attacks
Sophisticated adversarial techniques may evade detection. Re-test against emerging attacks and do not treat a detector result as a final verdict.
Generalization Bounds
Performance can vary on novel generation methods and unusual video styles. Test representative samples and review the published methodology before production use.

What video formats are supported?
The free web checker accepts MP4 files up to 10 MB. Confirm current API formats and limits for production workflows.
How fast is video detection?
Processing time depends on video length, resolution, encoding, and scan mode. Use asynchronous processing for long-form content.
Can I detect real-time video streams?
The public checker processes uploaded files. Streaming workflows require a separate sampling, latency, and integration design.
What's the minimum video quality required?
Low resolution, heavy compression, and motion blur can reduce useful evidence. Test the actual capture conditions used by your workflow.
Is my video data stored?
Retention can depend on the plan and scan mode. Confirm current retention, deletion, and data location requirements before submitting sensitive video.
