Day for night filming JB

The YouTube video below explain how to do Day for Night filming on a camera. I would like to test this to see if it would work for my film. There are several different ways I could film it. It could be day for night using the camera, day for night using final cut pro, day for night using both, or I could film at night. I am going to test all of these options out and decide which one would be best for my film.
