Thanks for the tip! Obviously the 1 pixel value applies to PAL/NTSC 576/480 vertical resolutions and if the vertical resolution of the input still is larger you have to increase the filter's pixel value accordingly. So for a 2048 x 1536 image I would use a 3 pixel 90° Motion Blur, right (1536/576 = 2.6)?
