Caedium Release Notes

Release notes provide descriptions of enhancements and bug fixes for each release of Caedium and its add-ons.

If an enhancement or bug fix is specific to an add-on, the add-on is listed in square brackets, e.g., [Builder]. Note that all enhancements and bug fixes are included in the Professional add-on, which is a collection of all Caedium add-ons.

Known Issues

  • If a media player does not launch after exporting an animation file (.avi), select File->Preferences, and then in the Properties Panel select the Export->Movies property, right-click on it, and select Reset.
  • Windows
    • Preview and playback of an animation file (.avi) created in Caedium requires Windows Media Player.
  • Mac OS X
    • Preview and playback of an animation file (.avi) created in Caedium requires an AVI codec for QuickTime, such as that provided by Perian.
    • Mountain Lion 10.8 Gatekeeper prevents Caedium from installing. For a workaround see "Caedium Workaround for OS X 10.8 Gatekeeper"
  • Linux
    • Preview of an animation file (.avi) created in Caedium requires the Totem media player.
