There isn't a colour negative film that won't give you a picture if you process it in ECN-2. Besides, Orwo says that you can process NC500 in ECN-2, too.
But, you are probably right, that "Process ECN-2
Only" probably is a clue that this is a Vision 3 5207 or 5219 with remjet. And if you look at the picture the base does indeed look like it has a remjet.
Should be interesting if this film appears in US. CineStill obviously will be forced to defend their "Cine" trademark. This film might get a new name, like "Ilfocolor 400 Motion Picture Film Tone". Just rolls off the tongue...
TRADEMARK EXAMPLES:
Trademark: CineStill®
Descriptors: Motion picture film for still photographers
CINESTILL® is a suggestive trademark, comprised of the words
CINE (deriving from the Greek "kine" for motion) and
STILL (from a film STILL photograph taken on the set of a movie or TV show during production). It may seem like an oxymoron but it implies distinction from either meaning.
“CINE film” is the term commonly used in English and historically in the US to refer to 8mm, and 16mm home movie film formats. It is not used to refer to larger professional cinema formats such as 35mm or 65mm film. "Movie film" is the common informal term for "motion picture film", the standard formal way of referring to 35 mm or 65 mm cinema film throughout the industry. Therefore “CINE” has acquired secondary meaning in the photography market (in addition to its use as an abbreviated version of “Cinema” for smaller motion picture formats) as a nickname for CineStill films, and has become distinctive through CineStill’s substantially exclusive and continuous use in commerce.
Although CINESTILL® film coexists with other motion picture based film larger than 16mm in the photography market, those products would not be accurately described as "Cine film” (benefiting from the goodwill CineStill has generated around the phrase). Instead, the standard way of referring to these types of films throughout the industry is as "motion picture film.”
