Avid Technology today announced the availability of its Symphony system for Mac OS X. Symphony 4.7, which we reported on in January, is “Avid’s most powerful Mac platform-based postproduction solution to date, offering real-time finishing capabilities such as color correction, 10-bit DVE and Ultimatte keying.” The company also today announced the immediate availability of Media Composer XL, Film Composer XL and Avid Xpress systems for Mac OS X. These new versions include real-time Symphony-style color correction, 23.976 fps project support for all Media Composer systems, and Avid’s new MetaSync technology, which allows editors to synchronize virtually any kind of metadata with traditional video and audio content.
