You don't know what settings you need until you actually get out there and start shooting. I don't think I've ever taken an Aurora shot with less than a 6 second exposure. But others have. ISO can be 400 or 4000. So Start at 6 second shutter, your widest aperture and 1000 ISO, and the quickest interval your camera can handle. 1-3 seconds max. Not 5. .... then adjust from there. If it's fast moving Aurora you may need to have a faster shutter, like 3 seconds. If it's a horizon glow aurora then you can easily use a 10-15 second exposure. Again. It all depends. It's like asking somebody how to score a point in basketball, there's like 10 different methods. Layup, dunk, 3 pointer, free throw, fadeaway etc. Just know how to operate your camera and you'll figure it out.

It should start counting the delay AFTER the picture is completed. I think. So you would get one photo every 12 seconds or five photos every minute. So it would take you almost five minutes to get one second of video and a full hour to get you 12 seconds of video.

The overall goal is to collect light at all times! Weaker/slower moving aurora will require longer exposure times, while faster moving/brighter aurora work better in timelapses if you have a little shorter of an exposure time. In any case, it's best to match the interval to the exposure time. On Canon you can cheat a little by just using the continuous shutter mode and a remote trigger. Set your exposoure to 5 second, and then lock the remote down, you get your 5 every 5 or 10 every 10 etc without putting any thought into the interval!
