 Vrecord is open-source software for capturing a video signal and turning it into a digital file. Its purpose is to make videotape digitization or transfer easier. Vrecord can capture analog and digital signals through a variety of inputs and can create digital video files in a variety of formats and codecs. Vrecord has been designed with needs of audiovisual archivists in mind.
