2.39:1 (21:9) aspect ratio shooting?

Note that the sensor aspect ratio is 4:3, so if you shoot anything other than 4:3 (the default) only part of the sensor will be used, and you will not get full resolution images. You can achieve the same result by shooting at the default, then crop the image to the desired aspect ratio.

There are apps on iTunes / App store which claims to shoot videos using the following aspect ratios.

(I would refrain from naming them as that would be interpreted as advertisement. )

Look for it yourself.

Up to a dozen different resolutions and aspect ratios including:

• HD Widescreen (16:9)

• Super 35 (2.39:1)

• Letterbox (2.20:1)

• Digital Cinema Initiative (17:9)

• Standard Definition (4:3)

• Ultra Panavision (2.76:1)

• Square (1:1)
