Do you use ND filters?
I realize that video, being a form of art, is mostly a "looks right, is right" application, but a general rule for videography is to have the shutter speed at double the frame rate.
For example, 30FPS should be shot at 1/60. Again, if it looks good, then I say go with it, but I do know this is a fairly rigid rule for professional videographers.
I generally set my WB to Sunrise/Sunset or lock in a better color. (I hope Yuneec adds the Kelvin WB feature soon)
I do use gorgeous mode, then set the ISO to 100 and Shutter Speed to 1/60. (I generally shoot 4K 30FPS)
I then use a corresponding ND filter from PolarPro to achieve the exposure I am looking for.
I have kind of been locked in to using the above shutter speed formula from handheld pro cameras.
With a typically camcorder, you will get a very unnatural motion if you have the shutter speed to high.
If others are getting good results from the CGO3+ with the higher shutter speeds, I may have to start experimenting with such.
