I think really u should do all your 16:9ing in FCp then do your compression in compressor…
1 quick choice:
Copy/paste your project into a 16:9 sequence and then scale, pan&scan the clips into the 16:9 space. Work in a smaller 16:9 image space if u are compressing it to a smaller frame size for the web anyway, that way u won’t lose any quality.
Compressor is great for compressing! Cropping, 16:9ing, letterboxing etc should all be done in FCP unless there is a very large gun to your head.
