Ingex is a 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 cassettes.^[1][2] Serial digital interface (SDI) capture is supported, as well as real-time transcoding (with MXF).^[1] Portions of the software suite also act as a network file server for media files, as well as archiving to LTO-3 data tape.^[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]

[edit] 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 Versioning 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 software and SDI IO cards. The media can then be edited by MXF-based editors, for example, Avid Media Composer.

[edit] Supported formats

Currently supported standard-definition (SD) codecs are:^[1]

• Avid-compatible JPEG codec resolutions known as 2:1, 3:1, 10:1, 20:1, 15:1s, 10:1m, 4:1m
• DVCPRO50 (50Mbps) and DV (25Mbps)
• IMX 50/40/30 (50/40/30Mbps)
• Uncompressed standard-definition video at 8 bits-per-sample and 10 bits-per-sample

Supported high-definition (HD) codecs are:^[1]

• DNxHD (VC-3) at 120Mbps and 185Mbps
• DVCPRO HD
• Uncompressed high-definition video at 8 bits-per-sample

libMXF supports:^[6]

• 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:^[7]

• 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:^[8]

• MXF OP-1A file container, containing audio, video, and timecode data (also known as OP-1A MXF)
• LTO-3 data tape
• Video SMPTE 384M uncompressed 4:2:2 video at 8 bits per sample in UYVY format
• Audio SMPTE 382M uncompressed PCM audio at 48kHz and 20 bits per sample
• LTO barcode information
• POSIX.1-2001 archive format (also known as pax Interchange format), a superset of the tar format which overcomes the 8 GiB limitation of tar format, to ensure future access to programmes

Metadata:

• Advanced Authoring Format (AAF) is used for storing edition metadata.^[9]

[edit] Supported operating systems

• libMXF:^[10] Microsoft Windows, Mac OS X, Linux
• Ingex Studio:^[11] openSUSE Linux
