Are there Chroma Keying plug-ins available from Ultimatte?
On the IRIX platform, yes. The user can access plug-ins through the Tools2 panel in Paint, and using the Plug In Actor in Animation. The Ultimatte plug-ins (v1.1.2 for Composer) are automatically loaded when you install Liberty. You can use them, but a red grid pattern will appear in the output (showing that they are in demo mode).
