(32/27) therefore the Sample Aspect Ratio that should be keyed in in MeGUI is 32x27 for NTSC 4:3 with resolution 704:480 480 ÷ 704 ÷ 3 x 4 = 0.88888...(10/11) SAR = 10x11 CROPPING without resizing won't affect the SAR Any comments on the way I calculate SAR? I took quite some time to understand that SAR is actually the ratio of every single pixel..not the ratio displayed by the video frame
