The problem is that a CIFormat data type is an integer based constant. So the question is, what key, and what object would I supply to the dictionary to specify this option?

I have no experience with Core Video but it looks to me like CIFormat is the key and the other three are the objects to supply.

CIFormat
Specifies the data type for a pixel format.
kCIFormatARGB8
Specifies a 32 bit-per-pixel, fixed-point pixel format.
kCIFormatRGBA16
Specifies a 64 bit-per-pixel, fixed-point pixel format.
kCIFormatRGBAf
Specifies a 128 bit-per-pixel, floating-point pixel format.


e.g. [NSDictionary dictionaryWithObject:kCIFormatRGBAf forKey:CIFormat]


Let us know if that works!
George
