What was the Roaster to have done?
Yeah, as Pyromania said it was suppose to have similar functionality as the Video Toaster.
optional Video Processor and Roaster Chip adds a wealth of additional features and functionality including:
-framegrabbing, genlocking, chroma keying, luma keying, realtime colour processing of live video
-provides an unlimited number of transitions and digital video effects including cuts, wipes, fades, special organic effects (soft- or hard edged), infinite range of flips, tumbles, page peels, image wrapping, picture in picture effects and more 24 bit 35 ns character generator
I believe these are photos of the Roaster (looks like an entire board that plugs in not just a chip)
There was also suppose to be the Opal Vision Video suite:
-a 19 inch rack mountable unit which includes video and audio mixing, switching and transcending connects directly to the Video Processor
-24 bit frame store
-nine video and ten audio inputs
-professional quality video inputs and outputs are available simultaneously in RGB or Y / R-Y / B-Y, composite and S-Video
-linear transparency key provides transparency control between two video sources on a pixel by pixel basis
-fully software sequenced audio mixer with smooth fades and full 5 band stereo frequency equalization
