I'll try to dig up my samples.  Rating at 25 is what I did.  3378 is processed in positive chemistry for soundtracks, but you can request it to be run in negative chemistry which would reduce the contrast by a noticeable amount, but you'd have to rate it even lower, maybe 12 ASA.  

 

Charles, you can email me at info@colorlab.com and I can get you a price for 400' of stock.

Here is a playlist of videos made from short test clips of 3378. The last one 3378 16 is where I got it right.

Another round of tests was given in order to develop 3378 as negative with lower contrast. Stand development was used. RO9 was the developer. This film is very sensitive to it. Development had to be adjusted. Time was shortened. Temperature was lowered. Agitation was deminished. Dilution was increased. Filters would help, too, but we're not used.

That stained glass is a good indicator of correct exposure. I determined Asa to be one click lower than 25.

BTW, I hand process in spiral tanks. The use of one ml of a premixed liquid developer in 400 ml of filtered water is very appealing to me.

I wanted to see the positive version of this frame. Looks pretty good to me. Decidedly green in some areas, but nothing that can't be corrected in-camera with the right filter (or in post, if you prefer).

Wow. I hope I can print it as well on PF2. Thanks. Silver IS green. Selenium gets rid of it

You're welcome. That's just Photoshop's Invert function. Certainly gives me hope for my own experiments with this stock.
