Today, visual and audio evidence is everywhere and can be found at more locations and from more diverse sources than ever before. From storefronts to restaurants, grocery stores to banks, traffic intersections to parks, surveillance systems are virtually everywhere. Add in dashcam footage and cell phone cameras, and you have a watchful eye in nearly every corner of every town. Forensic video analysis is the scientific examination and evaluation of video in legal matters, whether criminal or civil in nature.
Most of the footage is digital and file based. Gone are the days of Betamax and VHS. Digital video recorders generally record the audio and video to hard drives, SD cards, or other removable media. It is then our jobs to extract that media and transform it into usable evidence.
