Testing Startrc ND Filters

I used the DJI Air 3 with CPL, ND 16, ND32, and ND 64 filters to test whether the saying "You need an ND filter" is true. I've been hearing this every time I post a video. I've had these filters for as long as I've had the Air 3, but I mostly take nightly pictures. so I never use them here are the results.
