may be a stupid question but...

I'm also a Duet bride, and I don't recall anything about a wedding trailer. I do remember on the video they showed us, that they do one, maybe two 'highlights' - these were like 5 minute overviews of the wedding, I guess something like a trailer.

But I don't think they do trailers like Pennylane. Those video companies were just out of budget for us.

if u pay for it anyone will do it
ask Duet when will the highlights video will be available
it is called either a trailer, or highlights. so its not something special one particular vendor does

my videographer is Halo and they do it too, I just paid a bit extra for that
