Ingex
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 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]
Features edit
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.
Supported formats edit
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 (50Mbit/s) and DV (25Mbit/s)
- IMX 50/40/30 (50/40/30Mbit/s)
- 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 120Mbit/s and 185Mbit/s
- 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:[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)
- 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 48 kHz 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.[8]
