Frosthaus ( has released Sequence 1.0 for Mac OS X (10.8 or later). It’s available for US$19.99 at the Mac App Store in the Photography category.

With Sequence, timelapse photographers and video makers can import photos in most image formats supported on the Mac, including RAW, and preview the timelapse using a imeline-based interface. The deflickering engine in Sequence can remove brightness flicker from the source photos before rendering to video in industry standard formats, such as H.264 and Apple ProRes and so much more.

The timeline also renders a graph of any brightness flicker commonly caused by shutter or aperture variations in the DSLR source camera. According to Johan Srensen, the app makes full use of multiple CPUs and rendering on the graphics card, along with full 64-bit support. This ensures Sequence will be able to handle both large and small timelapse sequences with ease, he adds.
