Another Aurora Timelapse

Fantastic Bjorn. Having had my first experience of them in Iceland in March it just makes you want to see them more. These time lapses are much nicer than the ones I saw headlining on Yahoo News.
I wonder if you could half the interval for a smoother video for perfection?
I really wish I'd thought of timelapse at the time but I wasn't into it and I found at -9C I wasn't thinking that clearly!

Thank you so much Dave! Yes, I remember that you travelled to Iceland earlier this year, and shared some nice photos here at PU afterwards.
I am experimenting with the interval settings. If my memory serves me right, the settings were as follows:
First video sequence: ISO 1600, 13 sec exposure, 30 sec intervall
Second video sequence: ISO 3200, 10 sec exposure, 15 sec intervall
Third video sequence: ISO 1600, 13 sec exposure, 20 sec intervall
When making the timelapse, I set 10 frames per second in the encoder settings, which probably explains the lack of smoothness. The PAL standard is 25 f/s. The reason for me using 10 f/s is to keep the movement as slow as possible. I want to find a way to make timelapse videos with 25 f/s but rendered with slow motion. This can be done, but I guess it involves some advanced video editing software and $$$ I use Quicktime Pro on my Mac for timelapse, inexpensive and good enough for now. I have also seen Aurora videos recorded with very expensive pro video cameras (Sony), that can shoot one frame per second with high ISO, resulting in aurora videos that show the actual movement of the aurora. But I would have to sell my car (at least) for one of these video cameras, so I guess my K-5 will do for now.

PS: The vimeo videos have an HD video option. My video runs smoother on my Mac when NOT shown in HD.

Of course. I see the problem. You can't just shorten the interval as you need the long exposure.

I agree with you: Capturing the movements of the Aurora adds to the watching experience. Thank you for looking at my videoVery good idea making a video, much better than looking at static images. Thanks for sharing.

Yes, one needs the long exposures. I have just started recording and editing timelapse videos, I am sure there is still a lot to learnOf course. I see the problem. You can't just shorten the interval as you need the long exposure.
