Virtual file system (VFS). This allows editing clients, such as Avid, to use low-cost commodity storage for video and media files. ''Ingex Studio'' provides studio-style recoding, capture, transcode, and MXF wrapping for multiple cameras, also known as multi-camera tapeless recording. The software runs on commodity PC hardware and SDI IO cards. The media can then be edited by MXF-based editors, for example, Avid Media Composer.
