I conducted a series of tests and found out that the image resolution should be with a certain aspect ratio (4: 3) or (16: 9). Try to comply with these rules.

this is the video modes list for v2 camera: 1 - 1080P30 cropped (680 pixels off left/right, 692 pixels off top/bottom), up to 30fps 2 - 3240x2464 Full 4:3, up to 15fps 3 - 3240x2464 Full 4:3, up to 15fps (identical to 2) 4 - 1640x1232 binned 4:3, up 40fps 5 - 1640x922 2x2 binned 16:9 (310 px crop T/B before binning), up to 40fps 6 - 720P bin+crop (360 px L/R, 512 px T/B before binning), 40..90fps (OC: 120fps) 7 - VGA bin+crop (1000 px L/R, 752 px T/B before binning), 40..90fps (OC: 120fps)

1640x922 and 1640x1232 does not work when raw image is enabled. can you fix it?
