Video Forensics
Expert forensic analysis of video evidence for litigation including enhancement, authentication, deepfake detection, and frame-by-frame analysis. Court-admissible video examination with expert testimony.
Overview
Video evidence plays an increasingly central role in litigation, from surveillance footage in personal injury cases to body camera recordings in civil rights matters and social media videos in defamation claims. Our video forensics services provide scientifically rigorous analysis to authenticate recordings, enhance degraded footage, detect deepfakes and manipulated video, reconstruct events through frame-by-frame analysis, and extract critical details invisible to casual viewing. Our examiners use specialized forensic video analysis platforms validated for court use, applying techniques drawn from signal processing, computer vision, and digital media forensics. Every analysis follows reproducible scientific methods documented for expert testimony under Daubert and Frye standards.

Frequently Asked Questions
Can you enhance surveillance footage to identify people or read license plates?
Yes, we use forensically validated enhancement techniques to improve surveillance footage quality. This includes resolution enhancement through frame averaging and super-resolution algorithms, contrast optimization for low-light footage, stabilization of shaky recordings, and deinterlacing to remove scan line artifacts. We can frequently improve the readability of license plates, signage, and facial features. The degree of enhancement possible depends on the original recording quality, resolution, compression level, and lighting conditions. We provide honest pre-engagement assessments of likely enhancement outcomes so counsel can make informed decisions about forensic investment.
Can you detect if a video is a deepfake or has been manipulated?
Yes, we employ multiple detection techniques for identifying deepfakes and manipulated video. These include analysis of facial boundary artifacts where synthetic faces meet original backgrounds, detection of unnatural blinking patterns and facial micro-expressions, examination of skin texture consistency and lighting response, audio-lip synchronization analysis, compression artifact pattern examination for splicing detection, and frame sequence integrity verification. As deepfake technology evolves, we continuously update our detection methodologies to address new generation techniques. Our findings are documented with scientific methodology suitable for expert testimony.
How do you extract video from proprietary surveillance systems?
Many commercial surveillance systems (Hikvision, Dahua, Bosch, Axis, Pelco) use proprietary video formats and database structures that standard media players cannot read. We maintain specialized extraction tools and expertise for recovering video from these systems, including direct disk access for DVR/NVR hard drives, network-based export using manufacturer protocols, database reconstruction for corrupted or partially overwritten systems, and format conversion preserving original timestamps and metadata. We can work with counsel to coordinate on-site extraction from surveillance systems or receive shipped hard drives from DVR/NVR units for lab-based recovery.
Can you determine the speed of a vehicle from video footage?
Yes, we use photogrammetric analysis to estimate vehicle speeds from video footage. This involves identifying reference objects of known dimensions in the video (lane markings, road signs, vehicles of known length), calculating distances traveled between frames, and applying the known frame rate to determine speed. Accuracy depends on camera angle, lens distortion, frame rate, and the quality of reference measurements available. We provide speed estimates with documented error margins and can testify to the methodology and limitations. Results are typically accurate within 5-15% when adequate reference measurements are available.
