OS X 10.10 (Yosemite) does not include key files required for running commands like File>Import>Using QuickTime and File>Save As>QuickTime Movie that use QuickTime for Java. You can work around this problem by copying the files QTJava.zip and libQTJNative.jnilib, available at <http://imagej.nih.gov/ij/download/qt/>, into ~/Library/Java/Extensions, where "~" is your home directory. Yosemite hides the Library folder by default, so you will need to open your home folder and check "Show Library Folder" in the View>Show View Options dialog. Before copying the files, you will need to create the ~/Library/Java and ~/Library/Java/Extensions folders.
