Good question.
Quick answer:
Most of the still images you see are time exposures. Ibid saving lots of lights.
In reality, any one instant in time, they are not always that flamboyant.

The movement is so slow sometimes that time lapse photography is a better choice.

Yes, provided you use the correct exposure.
ISO, 800-3200
Aperture, between f2.8 and f5.6
Shutter speed, 1/30 sec. or 1/15 sec. (what ever that translates to in video)
Important, play with combinations of these settings to get the exposure right

I've been watching a lot of George Carlin lately. Your video camera takes 24 frames per second (lets say). How long is each frame exposed? Hmmmm. Let's try 1/24th of a second. Sounds good to me....

Check out Alan Dyer on Facebook. He along with Ronald Waldron do the auroras in Churchill at CNSC (Churchill Northern Studie’s Centre) and using expensive equipment got good results. But time lapse gives great results. I’ve been going up there February/March for the last 7 years for the lights doing stills and time lapse.

I attended a workshop on night photography by this person and she said video of auroras was one of her projects. I didn’t see any so can’t comment but I find her work to be pretty dang good.

Best of luck in your venture.
FWIW, she used Sony A-7s I think.
Edit: I just revisited her website and all I found was time lapse, so hmmm.... ?

My wife took a short video on her iPhone using the Night Cap app. It was a very intense Northern Lights night.

As long as one has a camera that does video, has a wide angle lense that opens up to f2.8, and operates well in the dark (not much noise at 6400 ISO) and cold, it should be able to get you the northern lights in video. Check in with our UHH astronomy section.
