Ingex

Ingex is an open-source ([1] Audio and video media files can also be stored on USB hard drives or Network Attached Storage.[3] The software is heavily used by the BBC, and was developed by the BBC Research Laboratory.[3]

Some of the early production projects which have used Ingex include a Foo Fighters music video, and the BBC television series Dragons' Den.[3]

Features

The different software products in the suite support:[1]

  • Multi-camera video capture in a studio environment
  • Video tape archive preservation
  • Acting as a server to Avid editing clients

Media Harmony[4] is a module for Samba 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.[5] 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.

  • uncompressed video or audio, DV25/50, IMX, JPEG, DNxHD and DVCProHD files
  • writes MXF OP-Atom files which can be used directly in Avid Media Composer and related editors

MediaHarmony supports:[4]

  • media_harmony - per-client .pmr and .mdb database files so there are no conflicts between Avid editors
  • mxf_harmony - on-the-fly unwrapping of MXF-wrapped DV essence so that a Final Cut Pro client can share the same DV media files as an Avid client

Ingex archive supports:[7]

  • MXF OP-1A file container, containing audio, video, and timecode data (also known as OP-1A MXF)
