capture resolution: 3840x2160 lens is a 1.8x squeeze 1 / 1.8 = 0.56 2160*0.56 = 1210 3840x1210 Now multiply your new vertical resolution by the desired aspect ratio to get how many pixels to cut. Let's say 2.40:1 is the desired result. 1210*2.4 = 2904 new resolution is 2904x1210. 3840-2904 = 936 :: what needs to be trimmed from both sides. 936/2 = 468. ///////////////////////////////// 2160*0.625 = 1350 COS_11D_LINE_6_TRANSMITTER_RECEIVER
