Here’s something from 1998: a blurb about Digital Studio

SOFTIMAGE|DS is a comprehensive video production environment application that runs on Windows NT machines. SOFTIMAGE|DS was originally called Digital Studio during its development stage, but was later released as SOFTIMAGE|DS.

SOFTIMAGE|DS 2.0 includes a complete real-time effect function for uncompressed data. SOFTIMAGE|DS, as the name suggests, is a comprehensive environment application that allows you to perform all the production processes in video production with a single interface. That means you can do video editing, effects, compositing, painting, audio and titles all in one software.
