Bigmouth... I'm using the term "false wall" for any wall that is not
one of the main permanent 4 walls of the room (i.e. the screen wall or the wall behind the last row of seats)."As for the consequence of doing 16:9 editing on a smaller image if you go constant height. Wouldn't the image be bigger than the size 99% of your typical audience views when you are sitting at you edit bay location?"
True...but with constant height on a 110 wide screen I'm only looking at a 3.9 foot tall image vs. a 5.16 foot tall image using a constant width system and unmasking the top or bottom. The total size of the image would be even smaller on 4x3 productions. I think the extra height of the 16x9 screen would really help out the display size of my 4x3 projects as well. I'm afraid I would feel I "cheated" myself out of the capability of using the full 110" (or 115") width for 16x9. I don't think I would feel this way if I were just using this room for 2.35:1 movies.
As for the constant width
setup...I was looking as something like this
It should then use the full projector panel for 2.35:1 when the U85 is in front of the lens. Full 16x9 would not require the U85. I could prob. rig a motorized mount for cheaper than the $995 price on the site.
I have been looking at the Sony Pearl, JVC RS1U, and the Panasonic PTAE1000U...it seems they all have pluses and minuses. I'll be looking at about an 18 foot throw distance for a 110" to 115" wide screen.
ARRRGGG. So much number crunching!
I also have to install the structured wire in the rest of the house...so I'm dealing with a lot more than just the theater and edit bay. All the wiring (including theater) is about 2 miles :-( LOTS of work ahead.
I should not complain now...I'll be happy when I'm done :-)
Thanks again for all of your input...it is really helping me in planning.
