Cellulo 2
Atvaark Development
Version 2.0.2 (September 28th, 2007)
  • Universal Binary
  • Script for the Linkinus IRC client
  • Minor user interface changes
Version 2.0.1 (December 16th, 2005)
  • Fixed an incompatibility with Mac OS X 10.4 (Tiger)
  • Minor user interface changes
  • New icon
  • Size of subtitles and other on-screen displays can be adapted to the size of the movie
  • Events like play, pause and time jump can have on-screen feedback
  • New audio codec column
  • Improved automatic detection of Unicode text encoding for subtitles
  • Improved compatibility with SRT (SubRip) subtitle format
  • Updated the Cellulo Simple Scheduler
  • New script for displaying in XChat the currently playing movie
  • A few other bug fixes and improvements
Version 2.0.0 beta (February 13th, 2004)
  • Highly extensible plug-in based architecture
  • New Preferences window
  • New contectual menu items
  • Reorganized information drawer
  • Bookmarks
  • Metainformations (like MP3 tags)
  • Cellulo now follows moved or renamed files
  • New columns
  • Improved textual search (you can use double quotes to search for expressions, and a minus at the start of a word or an expression means that you look for items which do not match that word or expression)
  • Information for each file is stored both in the Library and in the file itself (this is a security if the Library gets lost, and a convenience if you want to move your files to another disk or computer). Note that the information stored in the file is lost if the file is copied to a file system other than HFS or HFS+ (standard Mac filesystems).
  • Preferred decompressor can now be set for any media type supported by QuickTime
  • Scriptable with AppleScript
  • During playback, you can use the left and right bracket keys to align the previous or next subtitle on the current movie time
  • The computer won't sleep or dim the screen during playback
  • Cellulo can now act as a user interface to the mplayer command-line movie player (experimental)
  • Many bug fixes and improvements (and as usual new bugs... hence the beta version)
Version 1.3.1 (July 31st, 2003)
  • Improved loading time
  • Contextual menu is now available in full screen
  • Typing 'i' during playback to show the current item's name now always works
  • The screen used for full screen projection can now be chosen by placing the playback window on the desired screen before activating full screen mode (this feature was broken in version 1.3)
  • Fixed a bug that could make Cellulo crash when ejecting a CD containing catalogued items that have been removed from the library
  • "Smart DivX import" feature has been removed since DivX 5.0.6 makes it useless (DivX movies no longer have to be validated)
  • Preferences have been slightly reorganized
Version 1.3 (June 7th, 2003)
  • Improved overall performance (more reactive interface, reduced loading time)
  • Fixed issue that made MPEG-1 playback stop unexpectedly on some computers (this was and is still an Apple bug which I could eventually get around)

  • Many other bug fixes and improvements

  • .sub and .txt files no longer crash the application
  • Minor interface fixes

    FormatFilename must end with
    MicroDVD.txt, .sub or .mdvd

Version 1.1.1 (May 26th, 2002)
  • Fixed two bugs that prevented users of Cellulo 1.0 from upgrading to Cellulo 1.1 (one of these bugs also affected the Display Options settings)
Version 1.1 (May 24th, 2002)
  • New website :-)
  • Added undo/redo
  • Rewrote internal full screen system (this is a bit cleaner and should avoid some bugs)
  • Better support for multiscreen configurations
  • Corrected a bug that prevented subtitles in non-roman scripts to be correctly displayed
  • In full screen mode, the mouse pointer appears when the mouse is moved, and disappears after some seconds — it was previously always hidden
  • Added a per item zoom/ratio setting
  • File size appears in the list
  • User can now choose what columns to display
  • User can now choose subtitles text and background color/opacity
  • Added an option to make the movie window float above all applications
  • Added shuffle mode
  • Added dock menu
  • Added contextual menu to movie window
  • Volume is now saved
  • Double-clicking the name column no longer edits the name. This was rather confusing since double-clicking other columns plays the movie. Changing the name is now done by editing it from the information drawer
  • Many other bug fixes and improvements (and new bugs, but hey, that's how things go)
