ARRI's digital cameras can acquire metadata during recording. Metadata not only describes the file itself but can transport other information, like details on the camera settings, sensor speed, or a look file. These static types of metadata can be combined with dynamic metadata where the values change while shooting – like lens data information from the Lens Data System.
The complete metadata information is stored in ALEXA or AMIRA output formats: ARRIRAW, MXF/ARRIRAW, ProRes, and DNxHD. Also, the sidecar files *.ale and *.xml carry some of that information.
ARRI Meta Extract is available as a GUI (graphical user interface) for Mac OS X, Windows x64, Ubuntu, or CMD (command line) application for Mac OS X, Windows x64, Cent OS, Ubuntu, and SLES.
