Before copying the files, you will need to create the ~/Library/Java and ~/Library/Java/Extensions folders.CCNMTL: Project Portfolio: Using QuickTime on Macintosh 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. You can work around this problem by copying the files QTJava.zip and libQTJNative.jnilib, available here, into ~/Library/Java/Extensions, where ~ is your home directory. OS X 10.10 (Yosemite) and 10.11 (El Capitan) do not include key files required for running commands like File › Import › Using QuickTime and File › Save As › QuickTime Movie that use QuickTime for Java. In general, we strongly encourage scientists not to use MOV format for storing scientific image data, since Apple is not committed to maintaining backwards compatibility. It is likely that it will no longer be possible to use QTJ at all in future operating system versions.Īpple has also deprecated several old codecs (e.g., mjpb), with its QuickTime Player application no longer able to read them in current versions of macOS. QuickTime for Java has been deprecated for many years, and Apple is steadily phasing it out. QTJ is only available on Windows and macOS platforms, and only when running a 32-bit version of Java. ImageJ has built-in support for MOV files, but only via the QuickTime for Java (QTJ) library, which is Apple’s library for reading and writing QuickTime files from Java. See the Bio-Formats QuickTime supported codecs page for a list of supported codecs. The Bio-Formats plugins are bundled with the Fiji distribution of ImageJ.

It is written in pure Java, so those codecs will be readable within ImageJ on all platforms (Windows, macOS, Linux, etc.). The Bio-Formats library supports several, but not all, QuickTime codecs. There are several ways to import MOV files into ImageJ, each discussed below.

Whether you can open an MOV file in ImageJ will depend on several factors, including the codec used to store the movie, which version of which operating system you have, and which ImageJ plugin is used. QuickTime MOV files come in many flavors, which are known as codecs. The QuickTime movie format is a multimedia container format with extension.
