{{Short description|Software for digital capture of audio and video data}}
'''Ingex''' is an open-source ([[GPL]]) suite of software for the digital capture of audio and video data, without the need for traditional audio or [[video tape]] or [[video cassette|cassettes]].<ref name=ingex-sourceforge>{{cite web

}}</ref> The software is heavily used by the [[BBC]], and was developed by the [[BBC Research]] Laboratory.<ref name=cwuk />
Some of the early production projects which have used '''Ingex''' include a [[Foo Fighters]] music video, and the BBC television series [[Dragons' Den (UK)|Dragons' Den]].<ref name=cwuk />
== Features ==
The different software products in the suite support:<ref name=ingex-sourceforge />
* Multi-camera video capture in a studio environment
* Video tape archive preservation
* Acting as a server to [[Avid Technology|Avid]] editing clients
''Media Harmony''<ref name="ingex.sourceforge.net">{{Cite web|url=http://ingex.sourceforge.net/MediaHarmony/|title=MediaHarmony - Media file interoperability for non-linear editors}}</ref> is a module for [[Samba (software)|Samba]] [[Virtual file system|Virtual file system (VFS)]]. This allows editing clients, such as [[Avid Technology|Avid]], to use low-cost commodity storage for video and media files.
''Ingex Studio'' provides studio-style recoding, capture, transcode, and [[Material Exchange Format|MXF]] wrapping for multiple cameras, also known as multi-camera tapeless recording.<ref name="ReferenceA">{{Cite web|url=http://ingex.sourceforge.net/studio/|title=Ingex Studio - Multi-camera Tapeless Recording}}</ref> The software runs on commodity PC hardware and [[Serial digital interface|SDI]] IO cards. The media can then be edited by MXF-based editors, for example, [[Avid Media Composer]].
== Supported formats ==
Currently supported [[standard-definition]] (SD) [[codecs]] are:<ref name=ingex-sourceforge />
* Avid-compatible [[JPEG]] codec resolutions known as 2:1, 3:1, 10:1, 20:1, 15:1s, 10:1m, 4:1m
* [[DV (video format)#DVCPRO50|DVCPRO50]] (50Mbit/s) and [[DV (video format)|DV]] (25Mbit/s)
* IMX 50/40/30 (50/40/30&nbsp;Mbit/s)
* Uncompressed standard-definition video at 8 bits-per-sample and 10 bits-per-sample
Supported [[High-definition video|high-definition]] (HD) codecs are:<ref name=ingex-sourceforge />
* DNxHD (VC-3) at 120&nbsp;Mbit/s and 185&nbsp;Mbit/s
* [[DV (video format)#DVCPRO_HD|DVCPRO HD]]
* Uncompressed high-definition video at 8 bits-per-sample
libMXF supports:<ref name="ReferenceB">{{Cite web|url=http://ingex.sourceforge.net/libMXF/|title=LibMXF - MXF software library}}</ref>
* MXF
* 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:<ref name="ingex.sourceforge.net"/>
* 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:<ref>{{Cite web|url=http://ingex.sourceforge.net/archive/|title = Ingex Archive}}</ref>
* [[Material Exchange Format|MXF]] [[OP-1A]] file container, containing audio, video, and timecode data (also known as OP-1A MXF)
* [[Linear Tape-Open|LTO-3]] data tape
* Video [[SMPTE]] [[384M]] uncompressed 4:2:2 video at 8 bits per sample in UYVY format
* Audio [[SMPTE]] [[382M]] uncompressed [[Pulse-code modulation|PCM]] audio at 48&nbsp;kHz and 20 bits per sample
* [[Linear Tape-Open|LTO]] barcode information
* [[pax (command)|POSIX.1-2001]] archive format (also known as [[pax (command)|pax]] Interchange format), a superset of the [[tar (computing)|tar]] format which overcomes the 8&nbsp;GiB limitation of tar format, to ensure future access to programmes
Metadata:
