[Cin] removing letter boxing while preserving aspect

[Rob Prowel]

I have 3:2 content that is saved in a 4:3 frame with black bands at the 
top and bottom.

I want to remove the banding such that the output is a 3:2 resolution 
clip WITHOUT DISTORTING THE ORIGINAL CONTENT.

I've tried playing with the crop filter but the black bands remain, and 
the camera automation can remove the banding by zooming in, but then the 
left and right image sides get cropped out of the output.

Is there a tutorial for this exact scenario?
