I posted three time lapse videos in posts earlier this week. I used an app named Lapse It. Next time I will get the professional version because the free one only permits 240 p resolution with very limited special effect. The default period between photographs is five seconds. I eventually settled upon 22 frames per second when I rendered the films into mp4 format (abandoning the default of 30 fps). It was a pain uploading them from my tablet, but I eventually figured it out.
