If you're really concerned about scope being bigger than flat, the solution is to get a special longer scope lens just for scope-before-flat previews. Of course, looking smaller might not be all that hot, either.
Which reminds me, I keep meaning to figure out what focal length (shorter) we need to show letteredboxed flat trailers (of scope movies) such that they fill the scope image area. We occasionally get stuck with them (and we don't always have the scope trailer to replace it with), and I figure even with a cruddy old cokebottle it would look better. A really small flat image is just pathetic sometimes.
(In our multipurpose theatre venue, we're neither common-height nor common-width, but somewhere inbetween, and lacking masking. A shift from scope to flat doesn't look bad.)

quote: Joel N. Weber II the lack of optical port glass probably means that even the best lens will look like a cruddy old cokebottle in that venue.
Actually, if there wasn't any port glass..the light output would be the better since the light output doesn't have to suffer shooting through an actual liquid that is in suspension.
Why, basically the of the port glass is to keep the machine noise from heading out into the auditorium.
But, there is a trick that can be used if on really wanted open port windows and the noise can still stay in the booth - and that is to construct a double baffled port opening. the inside baffle, which is constructed out of cardboard and adhered to the inside port frame, has an opening that just allows the light to exit out with the edges just barely touching the edges of the light on all four corners, and the outside of the port frame is another baffle that has a wider opening with the same cutout in touching the edge of the light, just for the light to exit out to the screen.. The inside baffle really keeps the majority of the sound from exiting out the port, and the outside baffle keeps the sound from going out altogether since that baffle keeps the sound inbetween the two baffles.
How, I figured this out was that our port window was accidently broken, and being special glass, had to send the framework in (a Kelmar port assembly) to install the new glass. In the meantime is when I came up with this double baffle idea...and it did really work...

Well, I ran 2 flat trailers through a 90 degree rotated scope lense last night. I warned the audience before hand, cracked a joke about it, and they were fine. We are a small, single screen theater - there is no home office dictating what we screen, no army of incompetent projectionists (just one incompetent: me), no lack of port glass, etc. There's only a loyal audience and two movies that really, really needed promoting.
When it comes down to trailering movies that I think our audience would appreciate, and benefit from seeing, I'll do anything I have to to get them on the screen.
Slightly off the topic, but I haven't had much luck in the trailer request topic. Are people still looking at that?
