Time lapse aurora video question

[unsolicited_opinion]

Hoping some of you are experienced with time lapse videos.

I'm already planning for this winter's aurora season and will soon buying another camera, tripod, wide angle lens. I wish to have 2 camera setups next winter with one devoted to time lapse. I've already bought a intervalometer and I'm fooling around with it learning how to program it, and this summer I'm going to try doing some clouds and sunsets and that sort of stuff to get a feel for the process.

My main concern is finding a relatively simple software program that will merge all the photos into a video. Any help, suggestions, tips, advice anyone might have would be greatly appreciated.

Thanks,
