Does anyone know where I can cross reference the Kodak motion picture stocks to equivalent still films?

Athough Kodak's still films and motion picture films share some technology, they are distinctly different formulations. For color negative films, even the developing agent used in the process is different: CD-3 is used in the ECN-2 process, CD-4 is used for C-41.

There are a lot of differences between C-41 and ECN-2 not only in process, which John alludes to in his post, but also in intended applicaiton. For a long time, there has been a divergence in the needs of still and motion photographers. Flashbulbs and later electronic flash are different color temperatures than the tungsten lights that are favored by cinematographers, so even amongst a single film manufacturer such as Kodak, your still and cine films are going to be drastically different since they are designed for exposure with different light sources. I have seen ECN-2 that is custom processed in C-41 chemistry and the colors just weren't right on the subsequent prints. Also, if you were to compare the results from a still to a cine film, it would be difficult unless you were using daylight-balanced movie film. Kodak's fastest tungsten-balanced still flim is only ASA 100. Perhaps you should consider the possibility of spooling short lengths of cine film into cassettes for use in a 35mm SLR. It is more difficult to get processing now that RGB Labs has closed down, but I'm sure there are a few labs that'd help you out with doing tests if you told them that you would consider using them to process the footage you shoot for the film itself.

Regards.
