The Blackmagic doesn't have a 4:3 sensor, does it?
Taken from the BMCuser forum

It won't be a 4:3 mode but rather a crop of the sensor so that a 2x desqueeze will produce 2.4:1 exactly, rather than 2.66:1 as 4:3 does (which requires cropping of the sides for 2.4:1). And yes, we demoed this at NAB on an URSA 4.6K.
I believe it's a 3k crop
