Avid Matador

Matador (meaning killer in Spanish) was a paint application targeted at the television and film production markets. Running on Silicon Graphics workstations, its main features were paint, mask creation/rotoscoping, animation, and image stabilization/tracking.
Matador was originally developed by Gareth Griffith, Chris Steele, Dominic Jackson and Andrew Ballingall of Parallax Software in the UK beginning in 1989. Adopted by production studios and visual effects houses such as ILM, Digital Domain, Sony Pictures and many others, Matador was used on hundreds of feature films throughout the 1990s and early 2000s, including "Jurassic Park", "Forrest Gump", and "The Mask". In 1995 Parallax Software was acquired by Avid Technology, which continued to market Matador into the early 2000s, eventually incorporating its functionality into Softimage and Media Illusion.
