After installing RED you will have a BORIS RED FX and BORIS transition.
You can implythem as any other FX.
You should read the instruction in RED to configure Vegas to work with RED.
Many people are using Boris Red with Vegas. Search this board or download the Red demo to see how. Red plugs INTO Vegas, so why should Vegas list this in its options? Red is not a Sony product.
Thanks for the info guys, I'll have to break out the Red books I guess.
Buster, I use Liquid Edition also and it list Red in the options, so I thought it might in vegas also.
