Very interesting Edouard. Indeed, time lapse is a neat feature, and this one was done very well. But doing time lapse has gotten much easier. I did one of a sunset, just for grins.
Go ahead. Click on me. I'm very short.And I've got an app now on both my iPhone, iPod and iPad that can do it automatically. My sunset video was turned into time lapse post production, using iMovie. With the app, it slows down capture to the number of frames per second specified by the user, thereby eliminating the necessity of post production. Though, I would still run it through iMovie to add sound (if necessary), titles, credits, etc? I haven't used it yet. When I first got it, I tested it. Since then, the opportunity for good subject matter hasn't arisen.
Thanks for sharing!
