Hey All I'm interested in hearing any solutions for aspect ratio mattes for front projection systems. I've made them in the past for my RPTV but this is going to obviously be much larger in scale. I'm considering two aspect ratios: 2.35:1 and 1.33:1. 1.85 is too close to my 16:9 screen to even worry about, and extreme 2.70 widescreen amounts to a whopping one title in my collection. The idea I have in my head for 2.35 involves a matte cut to match the width of my screen frame (Da-Lite High Contrast Cinema Vision with ProTrim, 87" wide/100" diagonal). On the top corners they would have little ears that stick slightly beyond the frame borders and hang on pins poking out from the wall. For 1.33 they would be vertical mattes cut to height with width to match AR and use a similar type of hanging system. For materials I would use 1/8" MDF either painted flat black or wrapped in Duvetyne or similar black fabric. Other suggestions?
