CLamCam Video just released Timelapse Calculator, a companion app for both DSLR and video shooters allowing them to compute the key parameters necessary for creating time lapse videos. It can derive time lapse parameters for NTSC, PAL, and film frame rates. The maximum event durations is 52 weeks, although I suspect most users will use it for much shorter time lapse videos.

According to CLamCam Video, features include:

• Simple and intuitive interface
• Works for both video and still photography-based time lapse
• Multiple video frame rates possible (NTSC and PAL)
• Automatic unit conversions between seconds, minutes, hours, days, and weeks
• Save and retrieve computed values

Price: $2.99 from iTunes.
