Apple Computer has an alpha version of its Quicktime media integration technology that enables video, sound, animations, and pictures to be integrated on the Mac, via presentation in a 2.5 by 2.5 window: the three parts to QuickTime are a movie editor for assembling source materials, a compression manager for compression control, and a component manager that ties sound to the picture frame by frame; Apple says that Quicktime has special function boards that reads information from disk and decompresses compresses on the fly; the official announcement is set for June 3 in Los Angeles, but developers at the Worldwide Developers Conference were given a CD with an alpha version of the software and demo clips; Quicktime requires colour and a 68020 to run, so it won’t work with Mac Plus, SE or Classic.
