The easiest way to make a time-lapse video is to purchase a camera which has this function – a time-lapse maker if you want. One of the cameras which has this feature is Canon Powershot G16.
I take this camera with me everywhere. With this camera, I capture most of my time-lapses and I am really happy with the results. Videos are ready to watch as soon the timelapse is complete; no computer or specialised software needed. Check this out:
