AVC-Intra 100 Mbps Compression in a File Based Master Archive

File based workflows are gaining popularity for HD post production. Uncompressed files offer maximum quality but file sizes can become so unwieldy that file based workflow advantages are lost. Small file sizes can be created using low bandwidth HD distribution quality compression, but content then lacks the robustness necessary for post production and generation of various deliverables. — In the wake of the standard definition DV production revolution, independent productions have likewise embraced the efficiency of 100 Mbps DVCPRO HD, operating natively on IT platforms through the post process, balancing efficiency with broadcast quality performance, but not approaching master quality. — Master level compression, for archiving and generation of multiple format deliverables has traditionally achieved robustness and quality with high data rates. Mezzanine level compression proposals have suggested even higher bit rate “visually lossless” compression working in an IT environment. As real world applications and budgets change, these definitions might need reconsideration, and perhaps advances in compression technology and available processing power can close the gap between needed performance and file size.
