There are a horde of time lapse apps on the Apple iOS app store now. A while back I tested iMotion – Stop motion animation for iPhone and I’ve downloaded a few more.

Yesterday I noticed iTimeLapse had an update, listed in the fixes was – General crashy-ness fixed which sounded good and I decided to give it another try.

I set up my phone on the windowsill pointing at the trees and sky across the road. There is a choice of resolutions I choose 1280×960. I set the app to take a picture every 30 seconds and set it going. It seemed to be taking picture faster than that so I stopped, reset and started a few times (I even forced quit the app). Eventually I just let it do its own thing. After an hour or so it had taken 1333 images (Which the app tells me takes up 1339 mb on my phone) so I do not think that the Snap Interval is accurate/working! However the resulting video worked out fine.

On stopping the app you then have to render the video, my first attempt at one of the higher resolution settings failed, producing a block video, I tried again at a more sensible 640x 480 and this worked. The video was then watchable on my iPhone.

There are several export options, I tried the Vimeo option, which took a while but worked well and the Local WiFi Sharing.

I am a fan of a few other apps which have Local WiFi Sharing. Most apps that do this have a screen which shows an address to be typed into a browser, usually an IP address, although some support using bonjour in Safari. iTimeLapse does something different it show a link to with a 3 figure number. You visit TapShare on your desktop, type in the 3 figure number and that opens the local iP. TapShare is a service which offers this small utility to generate a 24 hour shortcode which can redirect to your local IP via an API which iOS developers can use. Being nosy I checked Safari and bonjour works too:

This video was 46MB in size and didn’t make it through my mail system to posterous, a quick export fromQuicktime, iphone setting, shrunk it to 9MB which upload fairly quickly: Evening Sky

Here is the Vimeo version:

I am sure this could be a useful app to use in the classroom for easily generating time lapse movies & animations.

I’ve illustrated this post with some screenshots, glued together in an animated gif, to save some screen space, please let me know if you think it is useful or annoying.
