Huge video exports

I love the fact that we can now export video straight from Cubase. but at present, my exports are 4 times the size of my imports.
I was working on 15 second commercials today, imported a 15 MB video-when I sent it to the client it was 63 MB. A one minute video at 70 GB was almost 300 when sent to client.

Steinberg, can we pretty please have more export options?
