It seems like the old Ektachrome ECO 40/25 would have been a better choice. It would work in all the cameras..
Actually the Ektachrome Commercial films 7255 and 7252 were ASA 25/16 but the 7252 could be pushed up to one stop and 40/25 could be adopted for the hypothetical normal new process. But: Kodak is extremely unlikely to make 7252 again as it used the hot and poisonous chemicals similar to the high speed Ektachromes, but with a different first developer and with the added soak and buffer for rem-jet removal. Reversal film is really not used any more in the larger gauges so it would be uneconomic to make it, and have a unique process for it, only for super-8.
I do agree that the film maker with less than a zillion dollar budget is better off with reversal film.
While negative might have somewhat better color and more latitude, transferring even 16mm and 35mm negative to video is a continuing battle with scratches and dirt. With negative, these flaws show as the whitest part of the picture. Negative cannot be run through an ordinary telecine.
I designed and installed the video equipment part of the original Rank and Bosch transfer suite at Alpha Cine. I recall that extreme measures had to subsequently be taken to have any chance of speck-free transfers. All film had to have extra long leaders and be cleaned at least once in an ultrasonic cleaner with full immersion in methyl chloroform. The transfer suite had to have micro-filtered air. The face of the Rank flying spot tube had to have ionized air blowing on it to keep microscopic dust specks off. An adjoining room had to be converted to an indoor waterfall to keep the humidity level high enough (even in Seattle!) to prevent static attraction of microscopic dust.
Customers and negative cutters had to be educated to wear white gloves, never touch the picture area of the film with anything, to handle it only under a clean air hood, and never let the film touch or drag on the editing table. And still it was (and is) a struggle.
Replacement flying spot tubes for the Rank cost $7,000 (the last I heard which has been quite a while) and do not last long. The technician to keep it working is expensive and the machine needs constant tweaking.
This is why reversal film can be copied to video for 11 cents a foot, while negative costs hundreds of dollars per operating hour.
