One way to accomplice what I want (widescreen photos cropped almost 2:1 floating in a white screen or ground) would be to make a new Backdrop with transparent middle and white boarder. I haven't bee able to figure out how this might be done in VF, or if, indeed, it is possible. I have made and added a PRESET under Video Event Properties, the Pan/Crop tab, but this doesn't help me with Text & Backdrops.
A little (more) help? Many thanks to all--
cheers--
