Earlier tonight we saw the release of the ProRes Decoder tool for QuickTime. According to Apple, this tool will allow QuickTime to play Apple ProRes 422 files, using the codec that provides "visually lossless, uncompressed HD video at SD data rates" for Final Cut users. This is the first version of the codec that includes playback on Windows machines.
"It is an excellent choice for mastering and can easily be transcoded to distribution formats like H.264. With new support for playback on both Mac and Windows computers, Apple ProRes can also be used for review and approval of Final Cut Studio sequences," says Apple.
The Mac update/plug-in can be downloaded for free from Apple's support downloads website, and if you are using QuickTime on Windows, there's a separate download.
