Video forensics entails the processing and scientific examination, analysis, comparison and evaluation of video for investigative purposes. It also involves the detection of video editing and tampering, the extraction of audio, the production of still images from video, clarification and enhancement of footage, and the identification of or comparison between items or people of interest captured on video.
