Before we walk though workflow for each camera, it's important to understand what a codec is. "Codec" is an abbreviated way of referring to compression and decompression. People who work at places such as the Frauenhofer Institute use color science and the psychology of perception to come up with ways to throw away data in a video signal in a way that only shows up a little bit on close inspection in ways we all hope our audience never sees, then reconstitute the video image into a much larger file when it's time to do something like edit it. QuickTime (.MOV) is not a codec but a container. An .MOV file, sometimes also referred to as a wrapper, may contain video made with one of a large number of codecs, including highly compressed codecs, such as MPEG-4 and its variant H.264, or very mildly compressed codecs such as Apple ProRes or DVCPro.
