ARRIRAW QuickTime Component
ARRIRAW is fully supported through QuickTime, which will preform all of the importing, playback, debayer, Exposure, ASA and color correction functions to the movie. All applications that use QuickTime can access all aspects of the ARRIRAW files. Applications including Final Cut Pro, Avid Media Composer, Compressor, can import and play these files without any sort of conversion or preprocessing steps. For the ease of portability with other users, you can quickly and easily convert an ARRIRAW image sequence to any other QuickTime movie format.
ARRIRAW Time Code
Time code is loaded right into any QuickTime application that supports time code tracks. Reel names (time code track labels) can also be added for applications such as Final Cut Pro. During export from Compressor, time code from the ARRIRAW image sequences can be baked into your destination media.
ARRIRAW Metadata
Many hardware and software vendors offer the ability to embed Metadata information directly into the ARRIRAW frames. A feature of these components is to retrieve these bits of information and make them available to your tools or applications. Final Cut Studio support is provided by the ARRIRAW Toolkit. With this package, Final Cut Studio will be able to embed the Metadata from the ARRIRAW footage, and preserve it inside your project files.
ARRIRAW Spotlight Plugins
The Spotlight Plugins enable your system to see inside the ARRIRAW image header. The Finder can extract specific information from ARRIRAW files when it does a "Get Info." You can search for time code, frame rates, encoding information or even "shot notes" from the "project" field. Simple shell scripts can also take advantage of the spotlight services and sift through frames for specific data.
ARRIRAW Anamorphic
Need to change the aspect ratio of your footage? The ARRIRAW Toolkit has
the ability to unsqueeze your imagery using a number of popular aspect ratios, without modifying the original. Preset Ratios include 1.78, 2.0, 2.35 or you can choose your own aspect ratio by entering a custom value.
