Gary Adcock explains the benefits of ProRes utilizing variable bit rate in this way: "ProRes, being a variable bit rate (VBR) codec, allows the more complex parts of the video to be encoded at a higher bit depth for more detail, while the less complex areas are encoded at a lower bit depth, thereby allowing for overall smaller file sizes [than. Media Info still showed it as ProRes422 HQ, and I can't tell the difference in quality. That’s happened to me.
