Find and extract motion events in videos.

DVR-Scan is a cross-platform command-line (CLI) application that automatically detects motion events in video files (e.g. security camera footage). In addition to locating both the time and duration of each motion event, DVR-Scan will save the footage of each motion event to a new, separate video clip. Not only is DVR-Scan free and open-source software (you can find DVR-Scan on Github), it's written in Python, based on Numpy and OpenCV, and was built to be extendable and hackable.
