Time lapses compress pictures into a video that's faster than normal
First, go on to the app store and buy a time lapse app. I use iLapse for $1.99, but there's good free ones too.
Then open the app and position your camera so it's still without touching it (I use duct tape, but only on my case) and view anything from nature....
...Or anything else moving.
Next set how many seconds will go by before every picture. Use a short time frame (.5,1,2,5sec.) for a smooth, long video...
...and a longer time frame for very slow objects. (20,15,or12sec)
Now set the fps (top left). Fps is frames per second, so 30 frames make 1 second of video. 30fps is smoothest for picture compression.
Here's a video I made. Enjoy:-)
