Final Cut Studio

Final Cut Studio is a professional video and audio production suite for Mac OS X from Apple Inc., and a direct competitor to Avid Media Composer in the high-end movie production industry. The suite was discontinued in 2011, and three of its primary applications - Final Cut Pro X, Motion, and Compressor - continue to be developed and were made available as separate applications for purchase through the Mac App Store. The legacy boxed version of Final Cut Studio is now only available to purchase through Apple's 1-800 number, therefore not online or in Apple Stores.

Components

Final Cut Studio version 3 contains six main applications and several smaller applications used in editing video. The major applications it includes are:

Cyclic redundancy check

A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents. On retrieval, the calculation is repeated and, in the event the check values do not match, corrective action can be taken against data corruption.

CRCs are so called because the check (data verification) value is a redundancy (it expands the message without adding information) and the algorithm is based on cyclic codes. CRCs are popular because they are simple to implement in binary hardware, easy to analyze mathematically, and particularly good at detecting common errors caused by noise in transmission channels. Because the check value has a fixed length, the function that generates it is occasionally used as a hash function.

The CRC was invented by W. Wesley Peterson in 1961; the 32-bit CRC function of Ethernet and many other standards is the work of several researchers and was published in 1975.
