Below you can see a sample of paragliding video recording. As pilot I'm trying to fly straight, but my harness (and camera) keep moving back and forth, left and right, every 2-3 seconds.
What is the best way to do a smooth time-lapse video out of this clip? A "plane alike" effect? I assume that I could use 1 frame of every ~5-second clip, just not necessarly uniformly distributed.
