This update contains important fixes for issues affecting certain users

Version 2.0

Released May 2013

New Features

Sequence 2.0 is now a document based app with its own project file

Now you can save your adjustments and work on them later again, with full undo support and of course support for Mountain Lion's Autosave and Versions features. Photos can be added and removed from a project, even from multiple separate folders.

White balance adjustments using keyframes

Set one or more keyframes to adjust the temperature and tint, Sequence will then interpolate the values in-between the keyframes so you can ramp the white balance up or down over time.


  • Sequence now uses less memory and behaves better under load using an improved rendering and analysis pipeline
  • Faster photo analysis
  • No longer causes excessive CPU usage when idle for some users
  • Photos can be added and/or removed from an existing time lapse
  • Much better undo-support
  • The timeline tracks can be selected and metadata and track settings have been moved to the right-side inspector
  • Deflicker options are now shown in the track inspector
  • Click and/or drag anywhere in the timeline to move the marker, not just the top ruler
  • Faster preview rendering
  • Removed potential dead-locks from photo analysis
  • Moved the timeline editing menu items to the "Edit" menu
  • Moved the toggle timeline tracks menu items to the "View" menu
  • Movie export settings are stored between launches and exports
  • Gracefully handle H.264 export size limits
  • Improved and tweaked UI in every nook and cranny


  • Exporting to fractional frame rates (such as 23.976 and 29.97) now uses a constant frames, instead of rendering VFR videos
  • Make the timeline keyboard controls work when the project window first appears
  • Automatically dismiss the preview FPS popover when done with editing
  • Don't show an "Export finished" notification center notification when an export is cancelled
  • Much fast sorting of photos
  • Additional checks for invalid images during load
  • Additional guards against unreadable images and more graceful handling if an unreadable image was still loaded
  • Improved time remaining calculation during image export
  • Many other tiny bug fixes

Version 1.1.2

Released february 2013

A small update with speed improvements and bugfixes.

  • Faster analysis of images. Should especially be noticeable on longer timelapses.
  • Fixed a crash that could occur if an export finished while Sequence was in the background.

Version 1.1.1

Released january 2013

Sequence v1.1.1 includes the new "Aspect Fill" scaling mode when exporting, which will crop off just enough to fully fill the image in the export resolution, as well as a bug fix for aspect fitted exports

  • New "Aspect Fill" scaling mode. The old "Aspect Scale" mode is now called "Aspect Fit"
  • Fixed issue where cropped and scaled images didn't get a black background when exporting, but instead showed a garbled image as background

Version 1.1

Released january 2013

Sequence v1.1 introduces a better deflicker engine, an updated user interface and the ability to export a timelapse as individual resized photos as well a critical fix for certain kinds of embedded thumbnails and other bug fixes.


  • You can now export the timelapse as individual photos in TIFF, JPG or PNG (EXIF data is kept)
  • You can now toggle the visibility of the deflicker track, which dictates whether the preview and export should be deflickered
  • The export button has been moved into the timeline header
  • Added ability to change the previewed frame rate

Other Changes

  • Fixed an issue where the size of the embedded thumbnail would be used instead of the real size of the image
  • The deflickering engine has been tuned to give even better results for common flicker scenarios
  • Handle files and folders being dropped on the Dock icon
  • A "Timeline" menu item has been added, with keyboard shortcut for toggling the Deflicker track
  • Default scaling mode for video export is now "Aspect Scale"
  • If you're not using a trackpad, Sequence now draws nicer and less intrusive scrollbars
  • Better formatting of aperture and shutter speed in the metadata inspector
  • Limit flicker corrections to what roughly equals 2.5 stops, to avoid noise appearing for extreme brightness differences
