- If you put a larger film back on recorder, and still only feed it
a. 4K rez, no matter what the rez for the film recorder is set or
b. larger file rez, but film recorder only 4K capable
then yes, you will have same pixel dimensions as for 35mm, simply spread out over
larger film area, and hence, lower overall resolution.
However, the way the scanning beam (flying spot) exposes the image onto film, this is
a far cry from "photographing a monitor".

Again, you see that your first statement is very much correct:
"But recording to film is very much dependent on the quality of the Film Recorder
itself..."
And to echo that, must continue to state that there is little if any discernable diff
on
MY film
recorder onto 35mm, whether
-fed a 4K file/run at 4K
-fed a 4K file/run at 8K
-fed an 8K file/run at 4K
-fed an 8K file/run at 8K
yet, there is a big diff onto 120 film, if NOT
-fed an 8K file/run at 8K
(I don't have a 120 back, but have examples from one using my recorder)
Hence my contention that for 35mm, assuming:
- you have 4096 x 2731 real pixels
- film recorder can truly image those pixels
That this 4K resolution, 11.1MegaPixels, is within a MP or two of actual 35mm film
resoution (at
least as far as E-6 and C-41 films go).
