Extended Time Lapse Camera

Take extended time lapse videos from hours to days. Allows you to specify time interval and playback rate. Runs on older iPhones that do not have a time lapse option as part of the built in camera app. Saves videos in camera roll.

Fault tolerant design saves individual frames during image capture. Frames are assembled into a video as a separate step. This insures successful creation of a video should the device run out of power.

Settings options:

  • Capture - immediate or delayed
  • Delay - 30 seconds, 1 minute, 2 minutes, or 4 minutes
  • Time lapse interval - 5 seconds, 10 seconds, 30 seconds, or 1 minute
  • Clear previous? - yes (starts a new video), or no (adds to the previous video)
  • Movie frame rate - 1, 8, 15, or 30 frames per second
  • Show date/time - yes adds a YYYYMMDD_hhmmss time stamp at the lower left corner of the video
  • Low (512x368) or high (1024x752) resolution video options

The latest version of the app provides an option for storing geo-coordinates (which can be turned off to conserve power).

There are two options for saving time lapse data:

  • Save as movie in camera roll (with or without location metadata)
  • Save as KMZ file for displaying data in Google Earth. These are typically large files that must be exported to a laptop using iTunes File Sharing, which is enabled for this app.

Examples

In the first example, the app was used to record time lapse imagery over a several hour period in an underwater device known as an AquiPod. Operating in low power mode, the app can run for over a day on an iPhone 4 with attached power pack.

In the second example, a hiker uses the app to record a 2 mile walk. Location data is automatically captured and stored. Time lapse data is exported as a KMZ file. The following figures from Google Earth show the full track, keyframes (every 10-th frame), individual frames over a short section of track, and a full resolution image at a specific location.

Here's the time lapse played back using our Trek Video app.
