| Avid DNxHD Is First Codec Compliant with SMPTE VC-3 Avid Technology announces that Avid DNxHD, a low bitrate HD production codec, is the first codec compliant with the new SMPTE (Society of Motion Picture and Television Engineers) VC-3 standards. The Avid DNxHD codec was submitted to the SMPTE organization as the framework for the VC-3 family of standards – and was approved after a two year testing and validation process. VC-3 standards enable content creators to facilitate efficient encoding and exchange of HD media, and are the first SMPTE standards for intra-frame, 720/1080 raster, 8/10 bit and 4:2:2 HD post production. With the approval of VC-3, the more than 30 Avid partners who have licensed the Avid DNxHD codec will further drive the adoption of HD workflows across film, TV and broadcast news by working with an industry standard codec. Vendors who design products that are VC-3 complaint, will enable interoperability with other industry VC-3 products – allowing Avid customers more choices when building workflows. This compliance also delivers the availability of a new standard for mapping VC-3 coding units into MXF – the professional standard for file exchange and media workflow. And, because VC-3 is an open standard, data in media archives can be accessed and used without being locked into a proprietary vendor. SMPTE VC-3 is the industry's only 720/1080 raster, low-bitrate, 8/10 bit, intra-frame, 4:2:2 HD compression standard, optimized for compositing, mastering, and multi-generational use. VC-3 is a family of documents referenced as follows: - SMPTE 2019-1- VC-3 Picture Compression And Data Stream Format; - SMPTE RP 2019-2 - VC-3 Decoder and Bitstream Conformance; - SMPTE 2019-3 - VC-3 Type Data Stream Mapping over SDTI; - SMPTE 2019-4 - Mapping VC-3 Coding Units into the MXF Generic Container. write your comments about the article :: © 2008 Computing News :: home page |
