Mikesull Posted January 8, 2014 Report Share Posted January 8, 2014 I have a fairly simple stage set up Q. Stage is a projected image flanked by two vertical monitors. The verticals are basic Sharp HD monitors rotated 90 degrees, but the projector is projecting a 16X9 1920X1080 HD image onto a square 8 foot by 8 foot screen. We plan on blacking out the edges of the projection to prevent projection bleed, but as far as Watchout stage set-up how do I set up the center screen? Do I use the final 8X8 foot size or 1920X1080 pixel size? (Imagery will be flowing across the screens.) Quote Link to comment Share on other sites More sharing options...

So you still need to output 1920x1080, use a pair of simple black still images on the top layer (or on an aux timeline set to always on top) to mask the unused portions of the raster. There is a chance the pixel density difference between the flat panels and the projected images is outisde the magnification correction range of WATCHOUT (±300%), not enough info to make that determination.

Mikesull Posted January 8, 2014 Author Report Share Posted January 8, 2014 So using a 1920X1080 center display will allow me to use over size stills and have them move across the screens even though the center projection screen is physically much larger than the HD monitors to either side?

Jonas Dannert Posted January 9, 2014 Report Share Posted January 9, 2014 We are missing key info here. What is the physical size of your projected screeen and the visible surface on the monitors in question? /jonas Quote Link to comment Share on other sites More sharing options...
Mikesull Posted January 9, 2014 Author Report Share Posted January 9, 2014 The physical size of the screen is 8 feet X 8 feet. The monitors are fully visible. Quote Link to comment Share on other sites More sharing options...
Moderator jfk Posted January 9, 2014 Moderator Report Share Posted January 9, 2014 The physical size of the screen is 8 feet X 8 feet. The monitors are fully visible. You are missing the point. Please provide the exact hight and width dimensions of the projected size of the full 1920x1080 raster. In a pinch, you can get by with just height.What you crop out of it after that is not important to the calculation. Please provide the exact height and width of the visible area of the flat panel. Please provide / confirm the exact resolution of the flat panels. With that information you can calculate the number of pixels per unit measure (dpi) for each display type. Then, you can calculate the correction to make an image spanning both display types remain the same actual size. Open the Stage Display Dialog Uncheck Width and Height same as Display Resolution and Lock down the Display Resolution at the display's native pixel count. You then convert the above correction to stage size in pixels to achieve the desired result. Quote Link to comment Share on other sites More sharing options...
Mikesull Posted January 9, 2014 Author Report Share Posted January 9, 2014 The projection screen size is 8 feet by 8 feet. The monitors native display is 1920 by 1080 and is 34 8/32" tall by 60 26/32" wide. They are mounted on stands and rotated 90 degrees.

Moderator jfk Posted January 9, 2014 Moderator Report Share Posted January 9, 2014 Flat panel calculationsConvert to feet to keep all dimensions in the same unit measure.34-8/32" = 34.25" = 2.854166667'60-26/32" = 60.8125" = 5.067708333'since the panel is rotated 90°1920 / 5.067708333' = 378.8694758 pixels per foot projection — 8'H consists of 1080 pixels = 135 / pixels per foot.90° rotated 1080-p flat panel — 5.068' W consists of 1920 pixels = 379 / pixels per foot379 / 135= 2.806440562, a correction factor inside of 300% 1920/2.8 = 684 (684.140625) 1080/2.8 = 385 (384.8291016) The projector stays native at 1920 x 1080 stage size, The flat panels 1920x1080 output become 684 x 385 stage size. To do this correctly, you would also need the measurement from flat panel image edge to the corresponding edge of the actual projected image (not your cropped image). And you would need the distance from the top of the projected image to the top of the flat panel images. You may have to use stage tiers to deal with that. The stage Display dialogs may end up looking something like this ... Quote Link to comment Share on other sites More sharing options...
