The iPhone app view is not captured 1:1 in my vision which makes for difficult framing, if framed exactly right, the resulting image is cropped at the bottom vs what was on the preview. Had anyone else seen this? Can you change to an aspect ratio that shows the same as the FPV? I checked and the ratio of the image in large 4384 x 3288, 4:3, 14.4MP should be matching exactly the 640x480 preview 1:1 but it doesn't. Is this common to all PVs or is this something specific to my unit?
