Forensic video analysis is the scientific examination, comparison and/or evaluation of video in legal matters. This definition is attributed to American Academy of Forensic Science. It is also the preferred definition by LEVA. LEVA is the most recognized trainer for military and law enforcement agencies seeking to become certified in video forensics.[1] [2]. 3D Forensic, Inc is the most recognized private company that provides advanced video analysis for use in criminal and civil trials [3]
Forensic video analysis usage
Forensic video analysis has been used in a variety of high profile cases, international disagreements, and conflict zones. Video forensics is necessary to show that images and videos used in court and media are verifiably true. Video forensics is especially important when media and governments use video coming from areas of state failure. Much of the video realized from inside Yemen and Syria have caused great political and public concern. Teams at the United Nation as well as within the governments around the world have utilized software and technical knowledge to ensure the information is accurate.[citation needed]
3D Forensic video analysis
3D forensic video analysis is often used to extract three-dimensional data captured within a two-dimensional video file. This advanced process allows forensic scientists to reverse engineer to data from many advantages points and answer forensic questions that traditional 2d analysis can not answer. Often, in police or military environments, 3D video analysis, taught by LEVA, is not able to answer important questions captured on the video. Often these public agencies will bring in experts in 3D video analysis, such as 3D Forensic, inc or Precision Simulations Inc, to use 3D modeling to reverse engineer the video to answer important questions, such as "What could the officer see before he discharged his weapon?" or "Who shot first" or when did the fatal bullet occur?"[4]
3D Forensic video analysis in high profile cases
3D forensic video analysis has been used in many high profile cases throughout the United States. Most recently it was used in the People v Jason Van Dyke shooting incident that occurred in Chicago by 3D Forensic, Inc. 3D video analysis was able to demonstrate when the fatal bullet was shot, that Mr. Mcdonald was coming close to Officer Van Dyke when he discharged his weapon and how many bullets struck Mr. Mcdonald while he was standing. [5]
A similar analysis was also used in the controversial police shootings of Mario Woods, in San Francisco, Jonathan Renfro in COEUR D'ALENE, Idaho, and Shaleem Tindle in Oakland, California. 3D forensic Inc was tasked with analyzing these cases using 3D video analysis.[6]
