I shot with red at 4k 16x9 mode. I brought it into FCP at 2048x1152 because of the down rez and set the pixel aspect ratio to square. Everything looks great, but when I export a web version I use 640x360 a 16x9 frame and set the pixel aspect ratio to square, and it comes out stretched. Actually, DV 16x9 looks closer than square. So why is it looks great in FCP with square set, and then when I export a web version it looks stretched? Is there a correct setting for Red 16x9 footage? I'll post some screen grabs below, Thanks
