As previously posted on my YouTube Channel, I did not get good results with a variable ND filter. I thought I try again with a better brand for a little more money, $79. It turned out pretty good, even though it’s color corrected/graded afterwards – and that’s what I care about, how the footage looks after post processing.
Editing to make it look like 2 cameras were used was a joy with Final Cut Pro. Doing something like this with a couple of tapes before the age of affordable NLE setup was nightmarish tedious. I don’t know how real film editor do it.
