Hi Bryn -
The only way I know how to do this in Vegas is to use the Pan Crop
command on a parent track and set the aspect ration to 1.85:1.
You can create an empty parent track and add a Solid Color Generator
to the length of the project in that track which will allow you to
see all of the child video tracks. Then choose the pan-crop tool for
that solid white track and crop it to 1.85:1 (in the preset drop-down
box)

feel free to email me at charles@cdmstudios.com if you have any other
questions.
